The Climate of Skiathos – Month-by-Month

Being a regular user of various Skiathos-related social media groups and platforms, it’s common to see questions asking what the weather is like on the island at a particular time of year.  If you’re reading this, it’s almost certainly because you’ve asked such a question, and have been directed here.

It's important to be clear that no one can guarantee what the weather will be like on Skiathos in advance, but it’s equally true that you can be given a good idea what it will be like, along with some idea of the possibility that it might be different to the average.

The following information is in month order, so just scroll down to the month you’re visiting, and read on.  Please note, if you’re going at the very start, or very end of a month, it’s not a bad idea to read up on what the weather is like in the adjacent month, too.

All figures are averages based on

the 30-year period 1991-2020


Skiathos in January, February, and March

Cool/mild, rather than cold.  The average minimum temperature in January and February is 8°C, rising to 10°C in March, the average maximum is 12°C, rising to 14°C in March with the mean average temperatures being January and February 10°C, March 12.5°C.  Those are the averages – the warmest days of each month can regularly be 18°C in January, 19°C in February, and 22°C in March.  The warmest temperatures recorded in the 30-year period were January 22°C, February 22°C, and March an eye-opening 31°C. The coldest nights are usually around 2-4°C, though it can occasionally be as low as -2°C in January.  Sea temperatures are almost always below 15°C, so too cold for swimming.

Rainfall averages are 80mm in January distributed over an average of 10 days, 70mm in February over 9 days, and 60mm in March over 8 days.  Sunshine hours averages are 3.5 hours per day in January, 5 hours in February, and 6.5 hours in March.  On average, it’s sunny for 37% of daylight hours in January, 48% in February, and 54% in March.  It has been known to snow, and snow quite heavily in January, though most years it doesn’t.  If you visit for a fortnight, you’re almost certain to see some rain, and there’s a reasonable chance the rain could last for a significant portion of your visit.

IN GENERAL - You can visit Skiathos at this time of year, but it won’t be for the weather or the swimming.

Skiathos in April

Very mild.

The average minimum temperature in April is 13°C, the average maximum is 17°C, with the mean average being 15°C.  Those are the averages – the warmest day of the month can regularly be 23°C, whilst the warmest recorded in the 30-year period was 26°C. The coldest nights are usually around 7.5°C, though it can occasionally be as low as 5°C, so you’ll definitely need a jumper and/or coat in the evenings.  Sea temperatures are almost always below 15°C, so it’s still too cold for swimming.

The rainfall average for April is 40mm distributed over 7 days.  The sunshine hours average is 8.5 hours per day.  On average, it’s sunny for 65% of daylight hours. 

IN GENERAL - April’s climate is a small, but steady improvement over the first 3 months of the year, but whilst the odd day may feel like summer, you’re far more likely to experience weather which feels very much like spring.

Skiathos in May

The tourist season for Brits starts in May.  That is to say, the first direct flight to Skiathos from a UK airport, and the first package holidays available from the big travel companies usually depart on or close to 1st May.

Warm.

NOTE – There is usually a fairly large difference between temperatures at the start of May when compared with the end of the month.  The average minimum temperature in May is 18°C, the average maximum is 22°C, with the mean average being 20°C.  Those are the averages – the warmest day of the month can regularly be 28°C, whilst the warmest recorded in the 30-year period was 31°C. The coldest nights are usually around 12°C, though it can occasionally be as low as 9°C, so a jumper or even coat for the evenings is advised.  Sea temperatures are usually around 18°C, so still too cold for swimming for most, though doable for the more hardy souls, particularly towards the end of the month.

The rainfall average for May is 40mm distributed over 6 days, so not much better than April.  The sunshine hours average is 9.5 hours per day.  On average, it’s sunny for 68% of daylight hours. 

IN GENERAL – May sees a significant step up in temperature over April, but otherwise the average climate across the month is another small, but steady improvement over the previous month, and starting to feel like summer.  May is certainly a time where it’s relatively important to consider whether you’re going towards the start or end of the month, as the averages improve fairly rapidly.  Having said that, you’ll be fairly unluck to have a fully ‘bad week’, and extremely unlucky indeed to have a ‘bad fortnight’ if you go for the first two weeks in May, whilst a visit during the second half of the month won’t be too much different to June.  The end of May is a far safer bet.

Skiathos in June

Warm-to hot.

The average minimum temperature in June is 22°C, the average maximum is 27°C, with the mean average being 24.5°C.  Those are the averages – the warmest day of the month can regularly be 28°C, whilst the warmest recorded in the period was 40°C. The coldest nights are usually around 17°C, though it can occasionally be as low as 14°C, so it’s best to consider taking a light jumper for the evenings, just in case, though you’ll get less use out of it the later in the month you get.  Sea temperatures are usually around 22°C, so quite cool for swimming, though most will find it bearable, particularly towards the end of the month.

The rainfall average for June is 25mm distributed over 4 days, so a big improvement over May.  Sunshine hours average 11 hours per day.  On average, it’s sunny for 73% of daylight hours.  Occasionally you’ll see steady rain in June, but more often it’s a quick, heavy thunderstorm.

IN GENERAL - June sees a significant step up in average temperatures across the month over May, but is otherwise just another small, but steady improvement over the previous month.  It’s drier, and there’s steady improvement in other areas; it’s now unambiguously summer.  There’s not a significant improvement between June and July, so this is the last time of the season when the part of the month you go shows any considerable improvement.  Like May, June is a time where it’s relatively important to consider whether you’re going towards the start or end of the month, as the averages improve fairly rapidly.  The weather at the end of June should be very similar to July and August.

Skiathos in July & August

There’s not a lot of difference between July and August, with the climate being warm-to hot.

The average minimum temperature in July-August is 24°C, the average maximum is 29°C, with the mean average being just over 26.5°C.  Those are the averages – the warmest day of the months can regularly be 33.5°C, whilst the warmest recorded in the 30-year period were 43°C in July and 38°C in August. The coldest nights are usually around 20°C, though it can occasionally be as low as 16-17°C, so a jumper shouldn’t be necessary for the evenings, unless you feel the cold very easily.  Sea temperatures are usually around 25°C, which is the warmest of the year, and good for swimming.

The rainfall average for both July and August is 20-25mm distributed over 2 days per month, so similar to June.  Sunshine hours average is around 12 hours per day.  On average, it’s sunny for around 83% of daylight hours in both months.  The rain, if and when it comes, is usually in the form of very quick, dramatic thunderstorms.  You’ll almost certainly not have a whole day washed out.

IN GENERAL - July and August’s climate is a small step up over June’s average, with only sea temperatures being a significant difference.  This is peak summer.  There’s not a significant improvement between late June and July/August, and whilst some figures take a turn for the worse in September, that’s mainly caused by a dip towards the end of that month.  In short, the climate on Skiathos is very similar from 1st July through to 31st August.

Skiathos in September

The climate changes during September, being unapologetically summer at the beginning of the month, but nudging towards autumnal as you near the end.

The average minimum temperature in September is 21°C, the average maximum is 26°C, with the mean average being 23°C.  Those are the averages – the warmest day of the month can regularly be just over 30°C, whilst the warmest recorded in the 30-year period was 36°C. The coldest nights are usually around 15°C, though it can occasionally be as low as 12°C; a light jumper is advised for evenings, especially towards the end of the month.  Sea temperatures hold up well, usually being around 24°C, which is still good for swimming, and not far behind July-August.

The rainfall average for September is 40mm distributed over 5 days per month.  Sunshine hours average is around 9.5 hours per day.  On average, it’s sunny for 76% of daylight hours.  It can rain for extended periods, but whilst you may possibly see most of a week cloudy and rainy towards the end of the month, that’s relatively unusual.  Nonetheless, twice in recent years there’s been heavy flooding, caused by heavy rain over half a week, or so. Both times in mid-September.

IN GENERAL - September’s climate is a step down from July and August, with only sea temperatures holding up.  Importantly, this deterioration occurs during the month, so whether you’re going during the first or last week or fortnight makes some difference.  Having said that, you’ll be fairly unluck to have a fully ‘bad week’, and extremely unlucky indeed to have a ‘bad fortnight’ if you go for the last two weeks in September, whilst a visit during the first half of the month probably won’t be too much different to July/August.

Skiathos in October

The tourist season for Brits ends after the first week of October.  That is to say, the last direct flight to a UK airport from Skiathos, and the last package holidays available from the big travel companies usually ends on or close to 7th October.

The climate changes during October, from hanging on to summer at the start of the month, to being unapologetically autumnal towards the end.

The average minimum temperature in October is 17°C, the average maximum is 21°C, with the mean average 19°C.  Those are the averages – the warmest day of the month can regularly be 27°C, whilst the warmest recorded in the 30-year period was 31°C. The coldest nights are usually around 12°C, though it can occasionally be as low as 7°C; a light jumper or coat is advised for evenings, especially towards the end of the month.  Sea temperatures continue to hold up well, usually being around 21°C, which is still just about fine for swimming, especially at the start of the month.

The rainfall average for October is 70mm distributed over 7 days per month.  Sunshine hours average is around 7.5 hours per day.  On average, it’s sunny for 68% of daylight hours.  As with late September, it can rain for extended periods, but whilst you may possibly see most of a week cloudy and rainy, that’s relatively unusual.

IN GENERAL - October’s climate is another step down from September, with only sea temperatures holding up.  And once again, this deterioration occurs during the month, so whether you’re going during the first or last week makes quite a difference.  Having said that, and given that the tourist season for Brits only covers the first week of the month, you’ll be fairly unluck to have a fully ‘bad week’, and extremely unlucky indeed to have a ‘bad fortnight’ if you go for the last week in September/first week in October.

Skiathos in November and December

The climate changes from autumnal to ‘mild-winter’ over these two months.

The average minimum temperatures are 13°C in November and 9°C in December, the average maximums are 17°C in November and 13°C in December, with the mean averages being 15.3°C in November and 11°C in December.  Those are averages – the warmest day of the month can regularly be 23°C in November and 19°C in December, whilst the warmest recorded in the period was 27°C in November and 23°C in December. The coldest nights are usually around 8°C in November and 3°C in December, though it can occasionally be as low as 4°C in November and just 1°C in December; a ‘big coat’ is mandatory.  Sea temperatures hold up fairly well in November at 18.5°C, which would be doable for some were it not for the cold air once you left the water.  In December this falls further to 15.5°C, which is a non-starter for most.  It has been known to snow, and snow quite heavily in December.

The rainfall average for November is 65mm distributed over 10 days per month, and 95mm over 12 days in December.  Sunshine hours average is around 5.5 hours per day in November and 3.5 in December.  On average, it’s sunny for 55% of daylight hours in November, but just 37% in December.  If you visit for a fortnight, you’re almost certain to see some rain, and there’s a reasonable chance the rain could last for a significant portion of your visit.

IN GENERAL - November and December are continuing steps down from October.  You can visit Skiathos at this time of year, but it won’t be for the weather or the swimming

I Tried DEET and I Still Got Bitten

Okay, that definitely happens.  What went wrong?  What are the possibilities?  And perhaps most importantly, based on my answer, what should I do next time?

Here are some possible reasons why you’ve been wearing DEET all holiday, but still got bitten.

For fun, try to rank them in order of likelihood.

1.     I didn’t apply it correctly.  Let's face it, that's certainly not impossible.  If you’re away for 14 nights and apply DEET 2 or 3 times a day, that’s a lot of applications you need to make sure you’ve performed perfectly.  Putting anything else on, do you ever ‘miss bits’?  Ever become distracted halfway through applying, and forgot which limb(s) you’ve already done? So, might I have missed a bit?  You don't have to miss a bit every time.  Just once.

2.     It got washed off.  Did I say 2 or 3 times a day?  If you regularly go swimming, you might easily up that to 5 or 6.  Or more.  And remember, for each application, you need to be as accurate and thorough as all the rest.  So, might it have got washed off?  You don't have to wash it off and not reapply correctly every time.  Just once.

3.     I forgot.  We’ve all done it.  Things we do regularly, day-in, day out, which you might think you'd never forget, but you just occasionally forget.  I’ve left my keys on my desk.  I’ve left my phone at home. I didn’t take my medication this morning.  Did I leave the iron on?  Did I put the bins out?  Did I turn the straighteners off?  Did I lock the front door?  Let’s face it, we forget things.  We’re human.  So, might I have forgotten?  You don't have forget every time.  Just once.

4.     I was bitten in-between applications.  True story.  In Florence recently I wore full length jeans and shirts (it was autumn) and I got one single, solitary bite.  It was on my left leg, near the top, over to one side, just underneath my front-left jeans pocket, that's the pocket where I always carry my wallet.  The mosquito would have had to bite through my jeans and wallet.  I wore DEET all the time, we had a plug-in in the room, so the only time I was unprotected was when I’d had a shower and went out on to the balcony to re-apply.  AH!  So there was a time, a small window of opportunity, where I had no DEET on, and wasn't fully clothed.  So, might I have been exposed for a short period?  You don't have to have been exposed regularly.  Just once.

5.     It wasn’t a mosquito.  Try this:

               https://www.prevention.com/health/g33011148/common-bug-bite-pictures/

So, are you absolutely, 100% sure it was a mosquito bite?

6.    The scientists who’ve tested DEET extensively and repeatedly for over half a century have all been lying when they tell us DEET works.  Or they’re shape-shifting lizards.  Or it’s something to do with Bill Gates, or 5G, or vaccines.  Or something.  So, are the conspiracy nutters right?

7.     There’s an omnipotent, all-powerful God, and I’ve upset her very, very much. So, are you out of favour with God?


Consider each of the above possibilities, and for each one, consider firstly the likelihood that it happened.  As I say, maybe put them in order.

Now, take each one in turn, and let's say that's what actually caused your bite.  Now, what would you say would be the most logical response to that happening.  For how many would that be “Stop taking DEET and try something else which is completely scientifically unproven.  Probably just something I read on the internet, because that has a track record of rock-solid accuracy."

For how many should it be “Continue taking DEET, I must just have made a mistake.”

I'd say, for numbers 1-5, the logical response would be that it wasn't a case of DEET not working, it's some other error, easily done.  In which case, it'd be daft to stop taking DEET, and for more sensible to try to eliminate the chance of error, as much as is humanly possible.

But if you're still not convinced, for how many would the logical response be “I’ll try something else which has been tested and proven to work, like PMD, picaridin, oil of lemon eucalyptus, or IR3535" and for how many would the logical response be to try something unproven, or something proven not to work, before exhausting all the ones already proven to work?

Actually, number 7 is my favourite…

It works for me

When discussing the efficacy of various anti-mosquito remedies, quite often someone will suggest one which has been tested and shown not to work, and when this evidence is pointed out to them they'll say "Well, it works for me!"  To be fair, that a compelling point - you get bitten, you try a remedy, you don't get bitten, therefore the remedy worked.  It's very easy to see how powerful that is in any case, and particularly when it's happened to you.

I think it's important to look at this claim.  In the first instance, and indeed almost certainly in every instance, the question should be "Did it work?" And there's no harm asking the question.

Scientific research into mosquito repellents has taken place constantly since the 1950s, and pretty much all suggestions have been tried and tested using accurate experiments and techniques.  The onus is, therefore, on anyone making a claim to others that  "It works for me" to explain why they believe it does, if the scientific evidence shows it doesn't.  You have a stack of science on one side, a few people's experience (possibly our own) on the other, I think it's valid to just pause and ask what might be going on.

Okay, here are the standards expected in statistical research.  Let's star with a binary claim - let's say a typical claim that taking a particular tablet (garlic, Vit.B) repels mosquitos.

A double-blind controlled test is necessary.  This would probably involve three people.  The first person wouldn't have any idea, or opinion.  We'd take 2 (we'll start with 2) people, give one a garlic tablet, and the other a placebo.  The two people involved wouldn't know which was which, nor which was preferred by the person conducting the experiment.  The person who gave them the tablets wouldn't know which was which, just 'Tablet A' and Tablet B'.  If we really want to get serious, we can make it a triple blind test, where the person who looks at the results doesn't know which is which either, they can just say A or B worked best.  Only after everything is completed is the truth revealed.

At each day's end the subject's arms/legs would be studied and photographed, with any bites logged.  The photos would be used to ensure any old bite wasn't counted twice.

For scientific standards of evidence we need to apply a little maths to the results.  The experiment should be completed on 10 separate occasions.  One of the two samples needs to clearly outperform the other at least 9 times out of 10; this could be done over 10 days. .At that point the efficacy of the successful product can be said to have been proven as working on that person (yes, it could then be said it "works for them") with a 95% degree of probability.

That's the maths.  That's what is required in a binary to test to say something works with more than a 95% degree of certainty.

Anything less than 10 separate experiments, and there's not enough data for the test to be statistically valid.  Anything less than 9/10 in favour of one product over the other is not considered to be proven.  We haven't proven to anyone, not even to ourselves, to any accepted standard that it "works for me".  To be clear, unless we've done the above, we've not even proven "it works for me" to ourselves.

Now that would be the basis for an experiment if, and only if, we expected everyone using a suitable repellent to never be bitten, and those without an effective repellent to always be bitten, but we know what's not true.  It'd also true that some people are effectively co0mpletely unattractive to mosquitos, and never get bitten, whilst yet others are very susceptible, or highly susceptible, to bites.  So we'd need to carry that experiment out with ten pairs of people, selected at random, and get the same at least 9 out of 10 times.

If you have no interest in carrying out the above experiments, that's fine.  Frankly, I wouldn't be prepared to do so either, so I've absolutely no criticism of anyone who doesn't fancy it themselves.  But in that case, the question is whether we should be offering "It works for me" as a counter-argument to properly conducted scientific trials.  What we'd doing in that instance is saying "Ignore the masses of evidence from hundreds of correctly controlled tests, and instead listen to my view, which I'm not prepared to test to any accepted standards of accuracy."

Unless we've done the above, we haven't proven to ourselves to the required standard of scientific accuracy that the remedy in question works, even just for us, let alone anyone else.  In that instance, we should not be making that claim to other people.  And we certainly shouldn't be offering it as counter-evidence to properly conducted research.

And finally, let's say we've done all of the above, and it does indeed work for us.  Even at that point, we've proven nothing other than that.  There are some areas where we're a little in the dark with on mosquito repellents, and one of the things we don't know about is why some people attract more bites than others.  We do know that there's quite possibly a genetic dimension to this, and that in turn may affect how different repellents work on you.  However, we do know from other research which repellents work best for most people.

So, returning to our first experiment, if we conduct that, and find garlic or Vit.B works for us, this does not discredit the decades of research on the matter, it just shows we're an exception to the rule, an odd one out, possibly a genetic aberration.

In that instance, we really shouldn't be offering "It works for me".  we should be saying "It works for me, but based on all the available evidence I'm the odd one out and it almost certainly won't work for you, and you should ignore my example - I'm the exception that proves the rule."

Avoiding and Treating Mosquito Bites - The Evidence

This blog post is a supplement to my other blog on the issue of avoiding and treating mosquito bites.  The other has a more conversational tone, but this one is just the evidence.  So this is just for the 'heavy reading' which supports what you'll find in the other blog.

DEET works.  It just does.  It's the best (or at worst the equal best) mosquito repellent, and in its higher concentrations, lasts longer than most others.  The other two proven repellents are Picaridin and Oil of Lemon Eucalyptus (or OLE).  Note - NOT 'Lemon Eucalyptus Oil' - that's something quite different.  Also, the rare IR3535 is good, though that's found more often in vaporisers (more on that later) than creams or lotions.

Links for DEET working, as well as Picaridin and OLE:

https://campushealth.unc.edu/wp-content/uploads/2016/07/InsectProtectionJuly-2016.pdf

And comparisons with IR3535:

https://www.medicaldaily.com/four-best-bug-repellents-deet-ir3535-picaridin-oil-lemon-eucalyptus-most-effective-says-ewg-247785

Link for 'Lemon Eucalyptus Oil' (sometimes called 'Lemon Eucalyptus Essential Oil') vs 'Oil of Lemon Eucalyptus' (OLE).  Please note the essential oil isn't very good.

https://www.hebebotanicals.co.nz/mosquito-repellents/

Note that DEET is often referred to as the 'Gold Standard', but different tests variously show one or other of these four as being marginally better than the others.

Regarding Avon Skin So Soft.  Avon used to sell this product under the sub-banner 'insect repellent'.  However, they've stopped doing so at the same time as they stopped using Picaridin as an ingredient.  You can check this yourself; just go to Avon's website and search 'Skin So Soft'.  These are the results.  None now say 'insect repellent' on the bottle, which in itself should flag up a warning.

https://avon.uk.com/search?type=product&q=skin+so+soft

Several of the products no longer state their ingredients, but those that do show that Picaridin has been replaced with 'citronellol'.

https://avon.uk.com/products/skin-so-soft-original-dry-oil-spray

Citronellol works, but only for a very short time, and is simply not reliable.  Given that there are several alternatives available, it would appear to be deliberately contrary to opt for a less effective repellent.  Details here:

By the way, whilst ultrasonic plug-ins don't work, you can buy vaporisers containing IR3535, and other repellents.  Scroll down here to "What else is bugging you" Q5.

Note, 'coils' that are left to burn slowly are effective, but there are concerns about their safety.  As there are alternatives, I see no point taking the risk.

Interestingly, if you've ever wondered why you get bitten but your partner doesn't, your attractiveness to mosquito bites may be up to 85% genetic.

https://www.webmd.com/allergies/features/are-you-mosquito-magnet

But there's nothing you can do about your genes.

Mosquitos appear to be attracted to CO2 and alcohol.  I strongly advise not exercising too heavily whilst on holiday, but avoiding alcohol is not an idea for which I'm prepared to offer the oxygen of publicity.  

Taking one-a-day antihistamines may reduce swelling and itching if you are bitten, with cetirizine being best:

https://pubmed.ncbi.nlm.nih.gov/8094995/#:~:text=These%20results%20indicate%20that%2C%20in,and%20delayed%20mosquito%2Dbite%20symptoms.

Applying various treatments after being bitten can help reduce swelling and itching, including ammonium solution (as found in After Bite):

https://pubmed.ncbi.nlm.nih.gov/9689301/

Or try calamine lotion or hydrocortisone cream:

https://www.geelongmedicalgroup.com.au/2018/11/how-to-get-rid-of-mosquito-bites-asap

I prefer the After Bite 'pen' as it's easiest to carry and least messy to apply.  You just take the top off and press the exposed 'pen' on the bite.  No need to run cream in, getting it all over your hands, etc.

I hope I've covered everything.  In each case I've chosen just one or two links, but you'll find many more in most cases.

I've tried to limit links to reputable studies and reliable sources.  If you want, you'll e able to find sites proposing quack remedies, and some look both professional and plausible.  But if something claims to work, look to see if there's been repeatable, peer-reviewed, double-blind test to support it.

Covid Conspiracies - The Questions That Need Answering (before you're daft enough to believe in them)

Many of us look on in bewilderment at the spate of ridiculous Covid conspiracy theories out there, and spend an inordinate amount of time trying to defend the perceived wisdom.  It's time to get off the back foot and take the challenge to the tinfoil hat brigade.  Before anyone even starts to argue that there's some sort of conspiracy, the following questions need to be answered.

What?

What is this conspiracy?  What is its purpose?  If there is a conspiracy here, then clearly it's quite massive, and has taken a lot of time and effort.  So why would someone do that?  What did we have before that they didn't like which will have disappeared if this conspiracy is successful?  What will we have afterwards that we didn't have before?

If we're really being fed vaccines full of microchips, what exactly are they going to do with that?

How?

How has this been perpetrated on us?  How do you manage to bring the world to a halt, economies to their knees, travel to a standstill?  How do you fill the wards of hospitals with people who are not ill, and statistics full of new cases and deaths which aren't actually happening, without someone being able to very clearly and easily shows that to not be the case?

Who?

This is the biggie.  Who is involved and who is to benefit?  As far as I can tell, if there is a conspiracy, all of the following must be in on it, and with a united purpose.

  1. Extremely nasty right wing dictators like Bashar Al-Assad of Syria, and Teodoro Obiang Nguema Mbasogo of Equatorial Guinea
  2. Very right wing, nominal 'democracies' like Jair Bolsonaro of Brazil.  Not particularly 'on message' with Covid, and currently playing catch up, but he admits it exists and is dangerous
  3. Centre-right democratic leaders like Trump in the US or Johnson in the UK.  Again, not always as 'on message' as you'd like, but spending (for Trump, 'spent') billions, and curtailing freedoms in a way which doesn't sit well with their general political philosophy.  But they're still on board.
  4. Centre-left democratic governments like those currently in power in France, Italy and Finland
  5. Progressive left wing governments like Jecinda Ardern's in New Zealand.
  6. Hard left democratic governments like those in Greece
  7. Very left wing nominal 'democracies' like Venezuala
  8. Extremely nasty left wing dictatorships like North Korea
And then there are the odd ones out like China.  What is that?  A communist, capitalist dictatorship?  And Iran.  A theocracy?

Let's not leave it there.  Look at opposing world views.  Israel's government and Hamas might immediately spring to mind.

What do they all have in common.  They all believe there's a threat to public health from Covid, to the extent that they've brought in unusual and extraordinary measures.  That's right.  The communists agree with the nazis.  The Thatcherites agree with the Corbynistas.  The Israelis agree with the Palestinians.  The religious Islamic leaders agree with the secular west.

Let's not stop with governments, what about the media?  Again, we might look at state controlled media in China, or North Korea.  Or we might look at media owned by capitalist, hyper-rich owners.  Or we might look at 'the mainstream media', which is, apparently, a bad thing.  And completely beholden to the establishment.

And yet this is the media who brought us Watergate, at the time of Nixon.  Who broke the news of secretly smuggling Cruise Missiles into Greenham Common in the time of Thatcher.  Or who railed against the MPs' expenses scandal.  Or who continuously scrutinise Boris Jonson's personal and financial affairs.  A media demonstrably NOT beholden to its leaders.

Outside of that, I need to go local with the UK here.  Any conspiracy, quite aside from the UK government of Boris Johnson's Conservative Party, would have to include the SNP in Scotland, Professor Chris Whitty, Sir Patrick Vallance, Jonathan Van-Tam, all of their subordinates, high-to-middle ranking health professionals under them, high-to-middle ranking civil servants, and thousands of administrators and scientists, not to mention the epidemiologists, virologists, and public health data collectors.

And what about the security services?  Where are the MI5/MI6/KGB defectors (and there are usually a good number) blowing the whistle?

What about the technology which controls our lives.  Apparently this has all been controlled by Bill Gates.  And yet it would also include the cooperation, not only of his old pals at Microsoft, but also his sworn enemies at Apple, needed to get the app on our phones.

So here's the question in short.  Why has this conspiracy happened, how on earth was it perpetrated, and who is responsible who had the power to cover it all up?

Because any conspiracy would require every single one of those nations, those politicians, those public officials, those scientists, those doctors, and those media to be involved, or at least consent to turn a bind eye...

...without a single one of them, anywhere on the planet breaking ranks.  Because none has.

None of those conspiracy theories has come from a country with a different political outlook to most others.  Or a genuine, proven independent reporter.  Or a high-ranking scientists.  Or any of the many tens, if not hundreds of thousands of credible voices which would have been potentially raised throughout the world had this all been a scam.

None of the conspiracies come from data officials in Belgium, or a team of doctors in Bolivia, or civil servants in Chad.

And here's the kicker.  I know that no one can possibly answer the massive, insurmountable weight of evidence I've offered here, but let's suppose they could.

That in itself would in no way prove a conspiracy.  It would only prove that a conspiracy were theoretically possible.  It would prove that it could be planned, perpetrated and hidden, but not that it had ever happened.  It's possible I'm in a conspiracy with Jeremy Corbyn, the manufacturers of Curly Wurly, and the bloke from the Go Compare adverts.  It doesn't mean it's happened.

And despite this lack of evidence, there are people out there prepared to believe conspiracy theories spread by Chuck, a 34 year old posting on FaceBook from his bedroom in his mum's house in West Virginia, who lives on a diet of delivery pizza and Cheerio's, and posts whilst sat in his soiled boxer shorts and t-shirt.

So, before you ever think about mentioning to me that there's any sort of a conspiracy about Covid, be prepared to answer all of the above first.

Why It's Important to Have a Covid Vaccine

When I first opened this blog, I said it was because the space constraints of FaceBook made it difficult to discuss some matters in the detail they require.  The necessity of having a Covid vaccine is one such instance.

It can be a tricky, emotive, and complicated topic, so I'll try to keep this as honest and simple as possible  So the following numbers are purely illustrative.  They're not be taken as accurate, pure science, but as an idea of why vaccination is important.

Firstly, let's look at a virus, any virus.  There's a lot of talk about the 'R' number.  That's just a measurement of how many people a person, on average, will pass the virus on to.  So, if a virus has an R of 1, what does that mean? It means that. if we don't change our behaviour (social distancing, etc.), if 10,000 people have it today, then 10,000 will have it tomorrow, and 10,000 will have it in a week, and 10,000 will have it in 6 months.

Some of the original 10,000 won't have given it to anyone.  Some will have given it to 3 or 4 people.  But, on average, each one person will have infected one other person.

But what if it's a nasty virus and the R number is 3?  That means that each of those people gives it to 3 more.  So now, those 10,000 people become 30,000.  That then becomes 90,000.  That becomes 270,000.  That becomes 810,000.  That becomes 2,430,000.  That becomes 7,7290,000.  That becomes 21,870,000.  And that becomes 65.5 million.  The entire population of the UK infected from a starting point of 10,000 people, in 8 steps.  Of course, it'd never come to that, but that's just to illustrate how fast things can change.

But let's say we could reduce that.  Let's say the R number was reduced to 0.75.  10,000 would become 7,500.  Then 5,625.  Then 4,219.  Then 3,164.  Then 2,373.  Then 1,780.  Then 1,335.  And then 1,001.  That's what we've done with the Coronavirus with lockdown.  We've not got R down to 0.75, but we've got it below 1 by closing the pubs.

So how do vaccines help?  Some say that there's no point in being vaccinated against a virus if it's not 100% effective.  Well, let's say vaccines reduce your chances of getting the virus by 75%.  3 people out of 4 who would have got the virus no longer do.  But 1 out of 4 does.  That means those 10,000 people, instead of passing it on to 30,000 people, will only pass it on to 25% of those.  Which is 7,500.  So the R number has come down from 3 to 0.75, because of the vaccine.  So for a virus with an R of 3, if the vaccine is 75% effective, it reduces the R to 0.75.  Instead of growing by x3, it's shrinking by a quarter.

But what it some people aren't vaccinated?  How many people do we need to be vaccinated to control that virus?  Well, we know that we need enough for the R number to fall below 1.  Remember, an R of 1 means the numbers are stable, above 1 and the numbers with it are growing, below 1 and numbers are shrinking.  We said that the virus has an R of 3.  So  200 people  give it to 600 more people.  If everyone were vaccinated with a jab that's 75% effective they'd only give it to 25% of those 600, so that's 150.  200 becomes 150, that's an R of 0.75.

But let's say a quarter of those 600 weren't vaccinated.  150 would get it from not being vaccinated, and 112 (25%) of those vaccinated would get it, that's a total of 262.  So 200 people pass it on to 262.  So if the virus has an R of 3, and the vaccine is 75% effective, and only 75% of people get jabbed, the R remains above 1.  And if we don't want the virus to spread, we need to keep the pubs shut.

Let's try some more sums.  If 90% are vaccinated, 60 of the 600 would get it because they weren't vaccinated, and 135 who were vaccinated would get it.

60 + 135 = 195.  200 people pass it on to 195.  The R has just dipped below 1.

So we would need 90% of people to be vaccinated to bring the R below 1.  Or alternately, keep some lockdown measures in place.

So that's a theoretical virus.  What about the Coronavirus?

It's very difficult to say with any degree of accuracy where we are with Covid, because we're nor completely sure of the virus's true R number, nor exactly how more infectious the new variants make it, nor exactly how much the vaccines prevent spread.

But we do know that the virus has an R above 1 (a long way above 1).  And we do know the variants increase this.  And we do know vaccines reduce your chances of passing it on.

And we also know that we've only been able to bring the R down to below 1 with some pretty hefty changes to our lives.

And we do know:

  • The R number needs to be below 1
  • This virus has a natural, unchecked R of way over 1
  • There are only 2 ways to bring the R number down (a) lockdown measures, and (b) vaccination
  • The more people who are vaccinated, the fewer lockdown measures are needed.
  • The fewer people vaccinated, the greater the number of lockdown measures must remain
So if anyone thinks "I'm 25 and healthy, I've almost ZERO chance of getting ill, why should I bother getting vaccinated?" this is your answer.

If you want to go to the pub, or a gig, or on holiday, or visit your family & friends, or go to the shops, or see businesses re-open, or the government getting into greater debt, or return to a normal life, then we need enough people to be vaccinated to keep the R below 1.  If we don't get enough people vaccinated, we'll need to keep some lockdown measures in place.

Put another way, if enough people refuse to be vaccinated, the pubs may remain closed.

Avoiding and Treating Mosquito Bites


How to avoid mosquito bites is a regular topic of discussion for people visiting affected areas.

THE BLOG ARTICLE BELOW WAS UPDATED IN JUNE 2022 AFTER AVON REFORMULATED THEIR SKIN SO SOFT RANGE.

I was badly bitten in 2017 at Koukounaries on Skiathos, and almost chomped to death last spring on Crete. I decided to do something about it for my Skiathos holiday last autumn, and research things a little.

In the past I've simply not bothered with creams, and just stuck to taking my usual antihistamines.  I don't know why, when it clearly hasn't worked!  For this holiday I resolved not to suffer like I had in April.

But I didn't want to hear old wives tales, I wanted solid, scientific evidence as to what really works.

The Research

Firstly, the lotions/sprays/creams.  I've read quite a few online scientific/medical reports, and watched a few videos.

Here's a good one showing just how good DEET is.


That really does seem to work.  Reading a few articles in scientific/medical journals, the scientists appear to think DEET, PMD, picaridin and oil of lemon eucalyptus (NOT Lemon Eucalyptus (Essential) Oil) are all pretty good.  There's a story that the SAS use Avon Skin So Soft, which sounds bizarre, and old-wife-tale-y, but there's nothing secret or magic about it, it just happens to contain picaridin.  ** Please see the footnote about Avon Skin So Soft.

Looking at all of the tests combined it looks like DEET is maybe just slightly better than the others, though there's not a lot in it.  The % concentration of DEET in a product above 15% doesn't appear to make that product 'better', it just lasts longer, between 15% and 50%.  However, some people get rashes and other side effects above 30%, so that looks like the best bet if you think you might not react well to it.

I know some people say "Nothing works for me!", but when you look at the tests which have been done, I think anyone wearing 30% DEET who still gets bitten is most probably not applying it correctly, not applying it often enough, or applying it correctly but then inadvertently washing it off. 

The little buggers hate it, and I don't care how juicy and/or nice-smelling you are, they're simply not going to land on you if you apply that correctly and frequently.

Next up, toiletries.  To help not attract the mosquitoes, it's best to use un-fragranced ones.  There's no use wearing something which effectively negates the lotion.  So that's soap, shampoo & conditioner, antiperspirant and shaving cream.

Because it's not always practical to apply a repellent just before bed, or one that lasts all night, a plugin has been proven to help.  But one that emits a repellent liquid, not an electronic signal, or high-pitched whine.  They've been shown to be useless.

If and when you are bitten, antihistamine can help stop or reduce itching.  I know that already, but what I didn't realise is that there are different types of antihistamine, and that some work better than others when specifically reducing mosquito bite irritation.  Apparently cetirizine is best.  By the way, it's not as effective taking one AFTER you've been bitten - preferably start well in advance of your holiday,  As a hay fever sufferer I take one-a-day between March and October anyway.

Finally, when I'm bitten, I find applying AfterBite is a big help:

It stings like mad for a few seconds, but I always think that's a good sign.  It certainly feels like it reduces the itching.  Again, like the above, there's plenty of good science behind using it.

Anyway, that's the theory.  In summary:

- Take the antihistamine cetirizine daily.
- Cover exposed skin with a product containing 30% DEET (or up to 50% if you don't get any adverse reaction).
- Apply an ammonia-based insect bite pen if you're bitten.
- Use a plug in at night.
- Wear un-fragranced toiletries.

I decided to take the lot and see how it went.

Having looked at the science I decided to IGNORE:

- Garlic tablets
- Vitamin B1 and/or B12 supplements
- Marmite
- Plug-ins which emit an electronic signal or noise
- Wrist bands
- Citronella Candles
- Lemon Eucalyptus (Essential) Oil 

All have been tested, time and time again, and have been shown to have absolutely zero benefit.  Please note that, whilst Lemon Eucalyptus Oil/Lemon Eucalyptus Essential Oil are very poor, Oil of Lemon Eucalyptus does work - check the labelling carefully.

What I Did

So, what did I do?  Firstly, I switched my daily antihistamine to the Cetirizine.  As the effect can be cumulative, I started a month in advance.

Secondly I switched my toiletries to un-fragranced ones.  Simple Pure Soap.  Simple Shampoo and Conditioner.  Simple Soothing Antiperspirant.  King of Shaves AlphaGel.

Thirdly, I bought a Jungle Formula plugin for the room.

Fourthly, I took to wearing a 50% DEET formula on exposed skin.  Superdrug brand.  DEET is DEET, you don't have to pay extra for a 'named' brand.  However, Superdrug's own brand appears to have been discontinued, so you might have to splash out a bit more for Jungle Formula.  I have now found that Sainsbury's Extra Strength Insect Repellent (50% DEET) is the best value, at only £4 for a 100ml ca, vs £7.49 for Superdrug's Buzz Off and £10 for Jungle Formula at Boots (though that is a slightly larger can, and they sometimes do a 'buy-one-get-one-half-price' deal.

Finally, I carried AfterBite for if/when I was bitten.

The Results

First night didn't go well, but all my fault.  I plugged in my plugin, and checked the light underneath to ensure it was on.  However, I was unaware that the plug, positioned underneath the room's large, back-lit mirror, turned on and off with the switch to the backlight.  Subsequently, when turning the light off for the night, I also turned off the plug in. Result - 3 bites on my left hand.  I sleep on my right, so it was pretty much the only exposed part of my skin, other than my face.

From then on, I ensured that the plugin was on every night, and that I always sprayed exposed areas with DEET before going out.  This involved moving it to a different socket.  The unit worked well, but it became apparent after a few days that it was dripping in to the carpet below, leaving a stain, so watch out for that.

The result was zero bites * all holiday.  Bearing in mind that I'm usually a mosquito magnet, and used to ending up looking like I've had a bad case of chicken pox (particularly on my legs) I consider this a triumph.

* Now, the one exception.  On the penultimate day of my holiday I went on a 4x4 jeep trip up into the mountains.  It was during a similar trip in April on the Crete holiday that I suffered worst.  Subsequently I decided to wear a long-sleeved shirt and long trousers, treated with picaridin.  That lasted for 5 minutes, I didn't even leave the room.  Just too warm.  So, I applied plenty of DEET, and ensured my shorts, socks and shirt were covered in a clothing-based repellent.

The results were spectacular.  I will not lie, I did receive 1 (one) bite to my right forearm, but that was it.  Why?  I can only guess that I either missed a bit when applying, or that part of my arm was rubbed at some point.  That aside I was completely bite-free.  I cannot express just how much this enhanced my holiday.

One more thing.  I regularly see people claiming that one of the proven fails (marmite, B12, realigning their chakras) 'works for them'.  Without being rude this information is of no use at all, and could be dangerous.  Firstly, without a thorough examination and controlled testing, there's really no way to say that the remedy genuinely does work for them.   Secondly, even in the unlikely event that it does indeed 'work for them', then if the science says it doesn't work in properly controlled tests, then it's almost certainly not going to work for anyone else, or at best for an extremely small minority.  Perhaps that wouldn't matter if we were discussing something else.  But if someone is genuinely persuaded to avoid a proven repellent, and instead slops on something shown to NOT work, that could cause a very nasty illness, and is quite likely to result in unnecessary discomfort spoiling your holiday, or at least taking the edge off it.  At worst, mosquito-transmitted illnesses can be fatal, and even in relatively low-risk countries like Greece.  You might want to Google 'West Nile Virus'.  So whilst I'm sure some people mean well, and some perhaps genuinely believe they're passing on helpful information, this really isn't something with which we should be playing a game of chance.  No offence intended.  Playing heavy metal might help you reduce your headache, but that's no reason to recommend it to others.

In conclusion, I can only say that my experience supported the research.  I thoroughly recommend that anyone who suffers from mosquitoes follows the expert advice referenced in this blog.  Whilst I've included my own experiences, but ultimately it's the science that counts.

**A word of warning about Avon Skin So Soft.  It USED to work.  It used to contain picaridin, which is a known, tested mosquito repellent.  However, Avon appear to have changed the ingredients, swapping out picaridin, and replacing it with cirtronellol.  Now, the latter does have some repellent properties  However, effectiveness isn't quite as good as DEET and lasts for a mere 90 minutes, so if you go to the beach at 10:00 and return at 17:00 you're looking at an initial application just before you leave the room, then top ups at 11:30, 13:00, 14:30, and 16:00.  That's five applications.  That's awkward and time-consuming, the multiple bottles required are bulky, and expensive.  Similarly, if you're out for the evening, leaving at 20:00, expect to be topping up at 21:30 and 23:00.  In comparison, the lowest strength DEET on the market (if you can find it this week) is around 6-7%, which will last you for 2 hours.  15% DEET is good for 4 hours, and 50% DEET will last you most of the day, and a reapplication all night.  That's 2 applications of DEET vs 8 of Avon Skin So Soft.  Four times as much.

One 100ml can of DEET will cost you £4 (see above), whilst a 100ml travel bottle of Avon costs £3.  But as we've seen, you'll need 4 times as much Avon SSS as DEET so that's £4 for the DEET vs £12 for the Avon, which isn't quite as good anyway.

To be fair to Avon, their site does say that ingredients may change.  Please feel free to let me know if you see a change in formulation.

Okay, that's it.  But don't take my word for it.  Rather than clog up this blog with numerous links, I've kept those elsewhere.
