And the heat burst gave the highest temp of the day by more than 6 degrees! The 6am-6pm max was 26.1C.

Yes was just reading that tweet. Apparently it's a phenomenon known as a "heat burst".

Perhaps we should archive the Historic Heat Watch in a few days' time?

Do the hourly readings not count towards the daily max then ?

I was told the Faversham data hasn't been looked at yet. I've not been able to validate the 38.4C that is being casually bandied around. The Met Office don't appear to be mentioning it.

Looking at all the max data from yesterday, although we seem to have just missed out on the all-time record (or tied it, if you discount Brogdale, which when analysed was considered to be unrepresentative by a about 2C!) there must be a good chance that it was the hottest day in England overall in history?

Not sure how you would work that out, but in terms of the widespread heat it was remarkable. Maybe the mean of all weather stations, or of course the more basic CET - was it the record daily CET, anyone?

Its a bit of a shambles. Bedford breaking down and other stations being offline as reported by Rob K.

Perhaps the Met should invest some more money in reporting stations rather than constant revamps of their website, which I have to admit contains less info than ever. But that’s another discussion for another day.

On another note it was wonderful to share in the experience of the day with so many great people on here.

I'm eagerly awaiting Brogdale's result, although I expect that 38.4C would be right (it'd be most odd for the Beeb to misreport something like that.)

Brogdale is only a few miles away from me and as it was cloudless most of the day I wouldn't be at all surprised to see it take the maximum temperature recorded yesterday.
