I am intruged to see whether it would happen in July or August.. seeing as our July is warmer than August on average.. I am surprised that our highest temperature came in August.. I think the highest July temperature was 37.8C at Cheltenham? Early 90s some time..

The warmest part of the year is late July to early August, with 6th Aug being the warmest day of the year on average at 24.6C (compared to the July avg of 23.5 and August 23.2).
Greenwich recorded 38.1c in July 1911, but the temperature was discounted
10th August 2003, the day that recorded 38.5c, actually has hazy cloud form around 1:30pm and prevented temperatures from climbing further. As the high is normally recorded around 4-5pm in London in summer, I'm fairly confident it would've hit 40c had the skies remained clear.

Ahh where do you find this information? Sounds interesting!
I was going to say, 1911 was a pretty severe heatwave, what was the highest official recording from then? It's a shame that many stations have shut down since then, and stations such as Heathrow only opened 60 odd years ago
Also agreed about 2003, our plane events from the south always seem to have hazy skies though due to pollution from the continent

(1)Greenwich recorded 38.1c in July 1911, but the temperature was discounted

(1)There's also recordings from the 18th and 19th centuries recording 38 in the shade... But obviously these are also disputed! LOL
(2)Imagine if it was full sunshine... I reckon it could have reached around 42C or something?

Haha, vote UKIP! LOL
No, in all seriousness, if the high pressure came further north then I reckon that 40mark would have been well exceeded. Like in Northern France and Paris
That is an excellent point. Precipitation and dew points have been steadily increasing here in the Midwest making it far more difficult to see the long duration, and extreme temps we witnessed during the Dust Bowl.
Here are two graphs illustrating this
I don't think thats the case in the British isles during the summer. Its definitely a lot sunnier here, I mean this September it rained like 2 days.
