Was looking at an article in the Independent about the current heat wave.
This caught my eye as the article progressed to medium term forecast
"There is a normal chance of drier-than-average conditions, with the chances of above and below-average rainfall fairly balanced."
What a load of old Obblers

Ironically I am off to Spain for a holiday tomorrow, Its cooler there.
|
Only low 80s today in upper Ribblesdale, and unfortunately cooling down tomorrow onwards.
When I arrive in Turkey next weekend if it isn't 100F every day I shall want a refund....my mother explains it by saying that I was born on the warmest day of the year, so I just soak up the heat. My best friend, who is 3 hours younger than I, is exactly the same.
Enjoy Spain... already got 6+ 2 weeks booked in Moraira early 2018.

Rode into work - body armour, leather pants and waxed cotton jacket. Felt like I'd been boiled in the bag on a mere 7 mile journey....hot...
|
Bit of warm weather and the British go to pieces......
Yet they pay good money to go abroad to get "some sunshine"..." !!
|
Currently in Crete and I gather the weather at home is much the same as here around mid 30's C at sea level but we still have some snow on the mountains where we were yesterday.
Bit of cloud over the mountains today but still plenty warm enough here at sea level to be off for a swim
soon to clear the head of last nights ouzo..

Currently slating a 45 degree pitched roof. The temp' feels much the same🌞

Why go abroad when Penzance is over 30degress and has been all week so far?
Huge top floor all round balcony is brilliant and perfect for the middle of the night hours we keep!
Can sleep with all the full length/width bi-fold doors open all night up here and know it's safe too.

Why go abroad you ask Pat?
Because the temperature here in Crete is still in the 30's and will be for the foreseeable wheras I see Penzance is projected 18/19 degrees next week...30 degrees there is a five day wonder.....
Enjoy your holiday.

That's true and it's been down to an agreeable and comfortable 20 degrees today.
Some like it hot but some like it just nice and warm!
30 degrees for the foreseeable would be a nightmare for us.

If I want to cool off inside then the apartment is air conditioned, we have a pool and the sea within 20 metres to swim in Pat.....
If I want to I can be 2000 metres up in the most spectacular White mountains in less than an hours drive with only eagles and goats for company where it is considerably cooler and there is a silence you rarely find these days and you have the beautiful smells of wild herbs ..
Acres of olives,orange and lemon trees, fabulous food made with fresh ingredients ....I had the most delicious seafood risotto last night...even the chips and roast spuds are better , freshly dug potatoes , cooked in olive oil and sprikled with herbs and sea salt.
I love it here ..

I love the Greek Islands. Never been to Crete though have been to a dozen others. You are making me want to check the airline schedues.

>> Why go abroad when Penzance is over 30degress and has been all week so far?
Because when I booked mine I knew it would be 30c, when you booked yours you had no idea what weather to expect. My 30c is a nice dry comfortable 30c, yours is a nasty humid oppressive 30c,
Oh and your 30c is probably over now, mine will still be around for the next two weeks

Because you can get a month abroad for the price of a week in the west country. I have been travelling around the west country for the last week or so. It won't be believed by the thermal expert troll on here but my cars external temperature has maxed out at 34°C for four days running, dropping to 25°C today. I believe it is accurately calibrated.

So has ours ON, it's been unbearable.
A month abroad I didn't enjoy would never compete with two weeks n somewhere I love though!

These past two days it's been overcast here in Ribblesdale. Nobody sat outside the pub the last two evenings @ early doors. Fleece & long pants weather.... 12 degrees this evening. Neighbours have their stove lit the last two evenings.
Roll on Turkey & Tenerife
Friends with two kiddies were looking at booking a nice apartment in Carbis Bay, near Penzance. They decided to book a nice 2 bed apt with sea view on the Costa Blanca, with flights and car hire on top it was only 65% the cost of travelling down to Cornwall... guaranteed sunny days on the beach, cheap supermarket wine for Mum & Dad, meals outside daily, drives into the mountains and the experience of a foreign culture in the small villages for the children.
Hope it isn't too warm for them!

If you have time to spend in Alicante Zeddo ( we try to spend a weekend there when staying up the coast) rather than just using the airport, the Museo Volvo Ocean Race is worth a few hours, as is the hilltop castle, and Museum of Contemporary Art. We normally dine outside at one of the small restaurants on Calle San Pascual. We found one serving Alhambra beer and that area is full of similar restaurants frequented by the locals.
Buenas dias

All winter I've been calling on customers who were telling me they couldn't wait for summer and they hoped it would be a really good one this year.
Now, three or four days into a brief hot spell the same people are crying, "I can't take any more of this, I wish it would cool down!"
Me, I love it. Out all day and as brown as a berry.

I hope you will not regret that later. Earlier over-exposure to the sun led in later years to removal of an actinic keratosis (from my nose) as well as two nodular basal cell carcinomas (from one leg). Various other suspicious minor growths have been zapped with liquid nitrogen in the interim but I am due to have 7 suspicious new ones (on my face and legs) inspected shortly.

Drove into Cardiff yesterday, on the M49 between the M5 and the Severn crossing the car recorded 32.5deg, over the bridge it dropped to 30deg and then slowly crept up peaking at 36.5deg between Newport and Cardiff on the A48.
The car thermometer usually aligns with the forecast so cannot be too inaccurate - the highest officially recorded temperature yesterday was 34.5deg at Heathrow though I guess it's possible to have hotspots elsewhere where there is not an official weather station.
|
Official temperature is in the shade, your car wasn't, and all car temperature guages over read that shade temperature
Hate to tell you this, even yours
|
>> Official temperature is in the shade, your car wasn't, and all car temperature guages over
>> read that shade temperature
>>
I have found car temp gauges to be quite consistent car to car over the years, but for a 2ltr Dynamique S Clio that we had for a couple of years that would sometimes read -9deg on a summer's day and +40deg with ice on the ground (fundamentally a good car and good to drive though a succession of problems almost shook my faith in Renault).
However the questions is whether they record shade temp or not and in my understanding the location of the temp sensor is designed to do that when the car is moving and also not allow wind-chill to be a factor so they should, when moving, present an reasonably accurate shade temp reading.
|
They don't, they can't even get close to a shade reading. It's a giant hunk of metal radiating heat, it has an engine dissipating 100,s of degrees of temperature within two feet,
It works reasonbly in the cold, but heat? Forget it is tens of degtlrees out at 30/40
|
I have found them to be very consistent with weather reports as long as the car is moving, even in the sun.
The sensor itself is in the shade within the mirror housing, and provided it is dry the housing itself will reach ambient temperature quite quickly in the airflow.
It's certainly true that heat build up gives ridiculously high readings while parked but it's difficult for the housing to remain at that elevated temperature with a gale blowing over it.
|

Agreed, though I don't think they are all in the mirror housing.

The car is traveling in artificially high temperatures at road level. Caused by the road. I can even recall sitting in a ditch in a SAAB, some 25 years ago having slid off on ice, and while contemplating the folly of my ways the guage suddenly dropped from +6 to-1
They can never be accurate, it's just impossible given the application

They may just as well house one of their met stations within a steel foundry to record high UK temperatures.

i would imagine it's their highest recorded temperature and airfields use weather readings. Unless airfields should be exempt but then you might well start exempt other places.
|
Cities are hotter than the surrounding countryside, i.e. they are at a higher temperature. No need to adjust for it, that's the temperature.
Same with roads. The car will read higher because it's hotter there especially if there is no wind.

Eh, It's the hottest in July though not Jan, Feb etc? and July is the second hottest month so it's significant.
Though rather like first past the post electoral systems Heathrow could well be the 2nd, 3rd, 4th etc hottest ever and the hottest on other days rather than the overall hottest which is Faversham so it needs charts for all stations to be truly meaningful.

Understandable in your case you, as you often write "their" for "there" or vice versa!
Now for the bullies above:
I thought you had all decamped to the GOF pub to drown your sorrows there, and one or two had even promised they were flunking off on a permanent basis but obviously can't be trusted to keep a promise.
Never mind, I understand that after having had a few too many, your brains might be too fuzzy, in need of a brain bypass, and it explains your irrational incoherent and sometimes thuggish behaviour.
For the benefit of those who may now be sober enough to understand, I'll try one more time.
Say the ambient temperature of mass of air is 5C. That mass of air may be stationary or moving at varying speeds, but for the purposes of this physics lesson I am telling all you children (pay attention at the back, Zero, it included you) that the air temperature is a uniform 5C and we are at liberty to speed it up or slow it down as will.
If you place a human being in the midst of it, that human being (if he/she is not in need of brain bypass) will sense the temperature to be cool, very cool, cold or very cold - depending on the speed at which the 5C mass of air flows past the body. That perception of different "degrees of cool" from the real temperature of the air at 5C is what gives rise to the concept of "wind chill". The actual temperature of the air remains at 5C. Wind chill is a human "feel" perception thing.
Got it?
If not, I despair for the general population - because by all accounts the visitors to this forum are supposed to be more intelligent the general population.
You can name call me and slag me off as much as you like if that gives you satisfaction, but it doesn't change the laws of nature.
In the meantime the heat wave is over. It feels like 10C in the cool gentle breeze outside of my house just now.
The keyboard warriors might wish to try to pop out and chill a bit.

|
>>Got it?>>
As I started this by using the term wind chill out of context let me see if I can end it.
You're not wrong though you're missing half of the story.
Yes wind chill is a perception, the movement of air can cause us to perceive temperatures as lower than they really are.
Though as Manatee says the movement of air causes evaporative cooling which actually takes heat way from the skin, or any other surface containing water, to the extent that it actually cools. This because heat is lost from the moisture as it evaporates so the moisture left behind is cooler.
So in addition to the perception of the air being cooler than it really is, the movement of air does actually cause a temperature change in the skin.

I live just a few miles from Heathrow and there seems to be lots of weather stations just west of London, Kew Gardens, RHS Wisley, Hampton Water works, West Ewell, Chessington
Bracknell,
Heathrow is not always the hottest of that bunch.
Faversham area seems to be the hottest in the UK.
The National apple place at Brogdale has a weather station.
Gravesend area is also often very hot.

That's not my experience over many years with a number of cars but for the occasionally errant Clio III.
We had a hire car in Biarritz some years ago, a Citroen C4 Picasso, it was a very hot day, much too hot, the car reading went up to 43deg which we simply didn't believe until we passed various pharmacies with their illuminated temp sign that confirmed that it was verrrrry hot and then the locals, including our French friends were talking about it, and then it was in the media that specific conditions caused a short temperature spike of over 40 deg.

The most faithfully reliable car we have ever had was a '98 Clio that we bought nearly new, ran through to 2011/12, sorned and left in the drive for two years cultivating moss, put a new battery in it, it started first time, passed it's MOT and did good service for a son for another three years including many long trips up and down the country. Even the aircon worked until the end and it had never been regassed.
The Clio III 2.0 did not live up to the expectations set by this though same son now has a Clio III 1.2 TCE that is fine, going strong at 80k miles.

Just in case you really didn't know what I meant - I meant that the temp sensor is not directly in the air flow so is not affected by wind chill. Stick you little finger or of the window at 20 or 70 and see which one feels cooler ...
And I am talking generally about temp sensors in the oceans of car that out there, not BMWs pacifically ...

Hmm, not entirely sure about that though I know what you mean.

Wind chill is not a factor in this scenario, unless the housing/sensor is wet.
If you were sticking a part of your body out of the window at 50mph and the ambient temp was materially lower than 37C then it would be.

OK, that makes sense and of course on a car moisture can be a factor which must be accounted for in the design.
|
|
I don't think wet is really much of a factor. Water will blow off in the rain rather than evaporate, which it would only do slowly in high humidity anyway.
|
In my 4 recent cars with outside air temp display (Xantia, Berlingos Mk 2 & 3 and Roomster) all were broadly consistent with Met Office or Meteo France observations.
Xantia's sensor was in n/s door mirror housing. Driving through France with temp around 40 it would drop to 35 every time washer was operated to shift bugs. Windchill/evaporation cooling the sensor as the screen wash went back in the slipstream.
|
>> Wind chill is not a factor in this scenario, unless the housing/sensor is wet.
>>
"Wind chill" by definition is human perception of temperature. The ambient air temperature remains the real, true, temperature.
If the sensor is kept wet as in a wet bulb thermometer, you are then talking about the difference between "dry" and "wet" bulb readings - nothing to do with "wind chill".
|
Wind chill is not just perception (of the actual air temperature being colder than it is) it is also a real difference in cooling. The body is warmer than the ambient air and the higher the wind speed the greater the heat loss for fairly obvious reasons.
The point about wetness is evaporation which causes cooling. Related to what you are talking about with your wet bulbs and dry bulbs which is measurements related to humidity.
Your wet bulb will practically always read a lower temp than the dry bulb, which is showing the actual air temperature. If your sensor or its immediate housing is wet, wind or no wind, it will generally read a lower temperature than it would if dry. For the same reason as the wet bulb v. dry bulb thermometer.

Fully accept that wind chill was not the right term in respect of a temp sensor being in the airflow, rather evaporative cooling would be a factor if the sensor were to get wet.
I recall a discussion on here many years ago, or perhaps on HJ, about spraying water onto intercoolers, some said it would make little difference to the temperature of the air in the intercooler unless the water was chilled and in volume, whereas others understood the evaporative cooling point, that the liquid cools as it evaporates, just found this on BBC Bitesize - "The particles in a liquid have different energies. Some will have enough energy to escape from the liquid and become a gas. The remaining particles in the liquid have a lower average kinetic energy than before, so the liquid cools down as evaporation happens. This is why sweating cools you down. The sweat absorbs energy from your skin so that it can continue to evaporate."
|

real difference?
I bow to your superior knowledge over that of experts at the Met Office.
|
Your sarcasm aside, do you not agree that one will lose more heat in an ambient temperature of say 0C and a wind of 10mph than with no wind at all, relative humidity being equal?
I didn't say it wasn't a perception, I said it wasn't just a perception. One will feel colder - that's perception. One will be colder - that is more than perception.

Met Office explains how it calculates "wind chill" to account for perception of temperature by humans compared to actual temperature.
Actual temperature remains actual temperature.

Doesn't matter whether you ar anyone else agrees. It is what it is as described by the Met Office.

I don't disagree with the Met Office as it happens so I don't know what your argument is.
The temperature is the temperature. But you will still feel colder and get colder if there is a wind, and the chill factor is not an absolute or even an exact science. The actual effect, on perception and heat loss, will vary according to how well insulated the subject is so the calculation is standardised.
|
Two different things;
- the temperature is the temperature, it doesn't incorporate wind chill.
- wind chill reflects an approximate representation of the combined [cooling] effect of the temperature AND the wind will have on someone's body. Its entirely real, just not part of the temperature measurement.
|
|
Or, more briefly, "What Manatee said".
|
>>"Wind chill" by definition is human perception of temperature.
It would be extremely important in the winter months to check the wind chill index before going far on foot in places like Newfoundland. Even on a lovely sunny day.

Which is why the Met Office goes to great lengths to forecast wind chill. It takes account of how "heat is lost from the human body".

I was at Ascot on Wednesday and it was very, very, very hot! Got sunburn even with factor 50 slapped on.
Champagne not imbibed promptly got warm :-(
Lots of fillies in pretty dresses. :-)
Lost under £100 on the horses so not too bad a day!

I had a better day then. Bought a new dishwasher last weekend at John Lewis. Sales now started and the dishwasher has gone down in price by £110. So JL refunded the £110. But I had to go in with the receipt which was a bit of a pain.
I'll have to check if it comes down anymore because I might get it a bit cheaper.

I've had a bad Ascot too. Best one of my donkeys could manage was a very poor third :-(

Man tells his friend he is broke.
What do you put that down to?
"Running 2 cars"
BUT you don't drive!
One for the bookie & 1 for his wife.

Thought the figure was how long the effects of the sun cream lasted from a particular base point i.e 50 would be twice as long as 25?
Might well be wrong though.

No, it's nominally how many times longer you can stay in the sun for the same amount of UVB. So SPF50 should let through 2% of UVB. Recommendation IRRC is that it should be reapplied every couple of hours anyway, regardless of SPF.
There is a separate star rating for UVA, usually found on the back of the bottle.
I am more or less up on this as I have two baby grandchildren whose mother, and I wish to protect from harmful exposure.

Some pretty obvious points; egg sucking and all that, but we've had young children in somewhat sunny conditions for years.
Use SPF 50. But covered is better.
Don't think clouds offer any protection, they don't. Reapply every two hours certainly, and if they're swimming, or diving around on a bouncy castle, or anything else that might rub it off, then every hour.
Always a hat. Its cheaper to spoil / lose / damage / destroy a cheap hat then it is to get your skin repaired.
Shoulders covered when walking around.
If lying around reading, dozing, whatever, then under an umbrella.
If they are sitting around reasonably still, eating lunch for example, then always under an umbrella.
Remember water reflects.
Don't think the temperature or how hot you feel is related to the potential for sunburn, with or without windchill. Just because you're cool, doesn't mean they won't burn.
Once the look like they are beginning to get a bit red, its too late. Go inside and stop it getting worse.
Don't forget the areas close around the eye and the toes.
The best stuff is cream. However, you can get little 50ml pump action spray bottles which are great just to keep in the pocket for urgent need.

We're a pale freckly lot with a large sun hat collection, a bottle of SPF 50 in every car, and we slap it on before we go out. Sun tans are not us:)

Basically correct, I know because a daughter was involved in the 'sun safe' campaign last year.
She got threatening posts from sun-bed shop owners, but not nearly as scary as being interviewed by John Humphrys on Today!

SPF50 should nominally let through 2% of UVB, SPF25 4%. So to get the same amount of UVB you would get in 1 minute unprotected, you would need 50 minutes exposure with SPF50 or 25 minutes with SPF25.
In that sense the SPF50 lasts twice as long before you have got the same dose BUT any SPF should be reapplied every couple of hours.
These 'factors' are of course suspiciously precise - slap more on, you might get better, spread it thin and you won't get as much protection.

>>I am due to have 7 suspicious new ones [sun damage sites] (on my face and legs) inspected shortly.
Turned out to be 12, including one on the back of my hand which will likely need an operation.
I have deliberatively avoided direct sunlight for the past 48 years...so its gonna get you, in the end.

It was so scorchio in Turkey these past 10 days that most daylight ( non swimming) hours were spent under awnings on the gulet ( reading, snoozing, playing genga, drinking Efes beer, rose wine and even water).
When swimming I wore sunglasses and baseball cap, only taking them off when the sun was below the horizon. Despite a decent tan I always use factor 30, and with the heat...just over 40 most days, peaking at 46, the low humidity meant my hip pain completely disappeared.

Gracius LL, the Museo de Arte Contemporáneo de Alicante Maca was a good call. Just been, now having a cafe con leche in Placa de Ajuntament.
Done the Castilla on a previous visit

32 degrees today in Vendee (west France), lovely jubbly. I didn't enjoy the 13 degree temperature this time last week in Warwickshire..!
Even more surprising to me is how quiet it is here; I expected the holiday season to be in fill swing already!?
Rental car is a petrol Corsa, perfectly adequate for the job for a week. Bit thirsty at motorway speeds perhaps, like those 1.0 Ford engines...

It's not school holidays here yet, nor is it August when the natives throng the holiday spots.

The heat wave - Zero
