F#^{++]g freezing 

Met office Twitter have 31.7c at Wisley.

This was a most unusual day.

It was predominantly cloudy, but the bright 'bloom' shining through the cloud seemed to irradiate everything so that walking was uncomfortable. Not sure if the RH was reasonably low as on previous days but it felt like one of those exhausting humid-hot days.

Reached 29.7 in the shade here but was sapping. August 2020 has some 3 degrees higher locally but was more 'I'm close to an open oven cooloing' heat and felt okay 9-ish0.

Run Norwich which was due to take place on Sunday has been postponed due to "extreme temperatures" being forecast

The BBC predict temperatures of 25c in Norwich on Sunday

It has been very humid today. Dew points at one point were just shy of 20C and have spent most of the afternoon above 18C.  Winds have been very light adding to the sticky feel.

It's ridiculous these decisions being taken on the basis of superseded forecasts. The Met Office should never have put the warning out for Sunday.

The iPhone app (which as I discovered uses the IBM model) has toned the temperatures down to 30/34/33 for Sun/Mon/Tue in London. In Norwich it's 27/32/34.

Really barely higher than yesterday and today. It seems a bit over the top.

BTW Spain max was 43.9C in Merida. Just 3.5C off their national record. Tomorrow should see a 44 or 45, with 45 or 46 on Thursday.

Until now, I haven't been paying a lot of attention to next week's possible record heat as I had been hoping that this would just be an England (and Wales) only event just like those earlier hotter spells during June but I am now starting to get a bit concerned about one or two of the model runs which have appeared just lately.

These are of course, the same model runs which are still showing the possibility of record breaking heat down south. Luckily for us, it's still not expected to get as hot as that here but even with that, one of two of those runs have started to indicate that we could see temperatures of over 30°C here in Scotland, possibly even as far north as the Moray Firth up in NE Scotland.

One thing to bear in mind here,is that our own record high temperature here in Edinburgh is only 31.6°C at Edinburgh Gogarbank and that was only set on 25 July 2019, the same day that the more famous record was set down in Cambridge. If those charts are right which I have just mentioned, there is the chance that this record could actually be beaten on either next Monday or next Tuesday.

One reason why this is important is because I will be making my annual summer trip to Hawick in the Scottish Borders next week to visit my family. When I was down there last year, the weather was sunny just about all the time. Even with that, the temperature didn't get any higher than 27°C at any time. That is what we had here in Edinburgh just a couple of days, and is more than hot enough for me.

This means that my upcoming trip down there has the potential to be even hotter than that, especially to start off with before it then becomes cooler and more unsettled for a short spell before high pressure possibly builds in again during the weekend before I return home.

When we had those really high temperatures back in 2019, I was lucky that we had a cooling breeze from off the North Sea which pegged the temperature at the botanic gardens in Edinburgh back to around 26°C on that same day.

During this summer so far though, we haven't had any cooling breezes from off the North Sea up until now because the wind has generally been from the opposite direction. Because of that, it is actually the north of Edinburgh which has been seeing the highest temperatures here in recent days, rather than the other way around.

Even if we did get those cooling breezes though, I'm not even going to be here to be able to benefit from that in any way. This means that if we do get temperatures of 30°C or above at the beginning of next week, I will then end up having to face the full brunt of that, which is something which I'm really not looking forward.

However, there are also a lot of model runs which still have us being a lot cooler at the beginning of next week, so I'm just hoping that it is those cooler model runs which end up being right in this instance.

Well I must say today was, to coin a richardabdn phrase, putrid. 

Heatwave conditions with 8 octas of cloud cover are awful. I spent most of the day shut away inside, with the darkness and sense of enclosure that you get in winter but without any of the bracing chill and coziness. 

One short walk with my daughter and after 5 minutes we were done and ready to head home. It was enervating, darkly foreboding, oppressive. The opposite of that feeling you get on a bright clear day when it’s heading towards 28C and there’s a light breeze off the river.

Hoping for less muck tomorrow. 

Was at work enjoying the clear air conditioning while outside very polluted in Langley.  Slough reached 31C and hottest under the clouds but NOT interested at all. If you felt the intense heat around you would estimated around 37 to 38C if was sunny today.  

Tropical night ! Overnight low was 20.9c. 

21.1C overnight low at Heathrow. And 22.1C at St James’s Park!

Does London City still not report. I have a feeling that would've been higher?

It reports half-hourly METARs to the nearest degree but I don’t think it is an official Met Office max/min station. 

The 0550Z METAR just dropped to 22C after being at 23C right up to 0520. 

See https://www.ogimet.com/display_metars2.php?lang=en&tipo=ALL&ord=REV&nil=SI&fmt=html&anof=2022&mesf=07&dayf=13&horaf=06&minf=53&ano=2022&mes=07&day=12&hora=06&min=53&lugar=EGLC

The Met Office still has an amber warning for Sunday, when temperatures will be lower than yesterday, and has no warning for Tuesday, which now looks to be the hottest day.
They are so slow moving sometimes, which is why you end up with events being cancelled unnecessarily. Anyone looking at the warnings would think Sunday might be dangerously hot. In fact it will most likely be about 80F in London.

Tbf GFS has 33c this morning,  you wouldn't want to be doing exercise in that. 

The warnings get posted only 3 days or so in advance, so expect one for Tuesday to appear soon. Presumably the MetO don't want egg on face if the modelling changes, and reckon that 3 days is enough for the public to prepare. But I agree that it looks odd for a yet higher temp not to attract a warning.

Not sure why the Jersey values are being discounted.  I know I am biased as I live here, but arguably it's more amazing that a small island surrounded by water regularly manages to reach the top spot in the 'British Isles' in the summer months.  We also topped 33c in June (breaking the Jersey June record).  Of course we benefit from proximity to a large land mass - it's why on a few winter days in the 80's we would max at -3c or so when the rest of the UK was above zero.  Regardless, I am getting excited about Monday when our record of 36c is under real threat!

You make a good point. I guess the size and depth of the water between Jersey and the Manche coast does not provide sufficient modification in the way the North Sea does for instance. 
There’s also the question of why the Jersey value is not counted as the UK maxima.

'Tropical nights' (i.e. min. over 20C) appear to have been recorded in several locations last night. Also Manston, Langdon Bay, Shoeburyness and Northolt. I'm sure there will be others too. 

I have nothing against Jersey and I am not trying to discount it as a high temperature, but it would be crazy to include it in the list of UK maxima, because Jersey isn't part of the UK. You might as well include readings from Gibraltar or the British Virgin Islands! (I appreciate that the Channel Islands don't have exactly the same status as those others).

I guess geographically the Channel Islands aren't part of the British Isles.

Seem not was forecasted to be that warm supposed to be cooler so if not the case then expect very warm week then very hot weekend.
