I think first chekpoint milstone shoudl be hottest July temperature pre-2015, which was 36.5C in July 2006. So we are close to breaking that one already.

Next is 1 July 2015: 36.7C. So nearly there too.

Then 37.7 100F. Then 37.8C which beats the July 2020 heatwave and puts us into second place for July behind 25 July 2019. 

Then 38.5C to go up into second place overall.

Finally 38.7C to equal 2019. 

yes, they are all f***ed but thats not weather related! 

The wind direction's been all over the place, really - I think what must have happened is I lost the modified-by-the-North-Sea air I'd enjoyed for an hour or so. It instantly went back up to where it would have been, hence the creaking.

(The fridge is now making a protesting loud noise, as is the portable a/c. As it's now above 35C, and the a/c only works up to 35C officially, I'm expecting the worst... I think I did the right thing in booking that hotel for tomorrow!)

It was hotter at this time of day a couple of days last week.

Dropped to 32.9C at Pett Bottom but humidity continues to dip. DP now 11.7C and RH 27.6%

Its 31.8C and it's surprised me how hot it is. After work swim will be fantastic!

Looking to break my all time high. Here are ten minute values here from July 25th 2019:-

1400 - 35.7

1410 - 36.1

1420 - 36.3

1430- 36.2

1440 -35.5

1450 - 35.0

1500 - 34.9

1510 - 35.3

1520 - 35.9

1530 - 35.9

1540 - 36.7  record 

Note there were two peaks, one at 14.20 and max at 15.40

Current temperature as of 14.10  is 36.3C so just 10 mins in front.

I think we have a surge of hotter and drier air from the continent in the past 45 mins. Something of note to those further NW in the course of the next two or three hours The dewpoint has plummeted.

Given the raging plume is still firing in I reckon it will be a 5.30pm peak today for most.

35.8° here. Just done a 30 minute very slow walk around the locale. A beautifully hot Mediterranean heat. Come back into the house at 26.2° and it initially felt air conditioned. All blinds and windows shut. Love it. More please.

Just noticed, humidity at 18%. Wow.

Remember though, cloud rapidly built up in the afternoon in 2019 to keep temps down. If somewhere can stay clear today then it could be game on.

I think we may have peaked here, down from 33.4 to 31.9 and rather grey.

My DP has also dropped in the last half hour to 0.1c !! 

Yup, now losing this relative coolness by climbing quickly to 29.4 C (39% H). Starting to feel it indoors too at 31 C in my still shaded west-facing hobby room.

EDIT: Just touched 30 C. Think it'll get to a point where the outside is warmer than indoors. 

Hope they come asap to remove the nasty clouds that forming around here giving shade up to 10mins ruining the rise, very poor today so far.

33c on phone.

25.3c ground floor.

26c upstairs.

Down to 31.8C and still falling. It really hasn't actually felt notably hot here today - we peaked at 33.5, which is a fair bit lower than in 2019 and 2020, but then today was never going to be a south-central England kind of day. Temperature inside is very bearable, with curtains and windows closed.

I think we will now see the peak of the heat move northwards, so don't discount a record yet in the Cambridge/East Anglia area.
