Seem Birmingham not reached 38C 100F? as there not on the list, nearest to me is Coleshill than Coventry which my app Nuneaton briefly reached 39C
Birmingham airport reached 37C and Winterbourne 37.4. Coleshill was the nearest to break 38 but didn't beat the old record, which was my cutoff for that list.
Incidentally, I have found a link to one of the other mystery manual stations, Denver Complex near Downham Market. It looks like they may only upload their data once a month as there are only figures up to 1 July!

So there's a very very outside chance we might have another challenger.
A better placed manual station appears on the Met Office list, Tetford near Horncastle in Lincs, but there is no sign of it on WOW.
