I wonder how long it's been since we last had a final week of August as warm (or indeed hot) as this in the southeast.
The mean maximum looks to be near 28 or 29 for the likes of Heathrow (having made adjustments for urban heat island effects), with a mean minimum of about 15 or 16, giving an overall mean of around 22 or 23 for the week.
I can't recall anything even close to that for the final week of the last 10 Augusts at least.
Time to do some digging - but if anyone knows some historical Heathrow stats I would greatly appreciate your insight
