Not sure if the Netweather feed has minute-by-minute data for all stations, but it has't picked up any 30s yet. Might have to rely on a manual station (and most of those in the southeast don't provide data on WOW any more)
Temp is still climbing here, 28.6 is the highest of the day.
And there it is, good old Heathrow with 30.0C at 1620Z.
Or perhaps not. Weatherobs said 30 but Ogimet says the 1620 reading is 29.0.
