I think the cloud will break, especially the further east you are.

Temps have certainly shot up today here - not surprised that Mildenhall is reporting 28. Bit of mid-level cloud making the sunshine a bit hazy from time to time.

Dodgy exposure, and it’s a lot higher than most surrounding stations. Then again, Gravesend was often much higher than other local stations.

The reading of 38.1C - 100.5F - claimed at Greenwich on the 22nd is now not accepted, as the screening conditions at Greenwich were nonstandard; it is more likely to have been about 36.1C - still quite a temperature, and the record for July (until 2006). 97F (36.1C) was also recorded at Epsom, favoured because there was shelter from the light southerly breeze."

In reality most days where Heathrow is the hottest location (and it’s not actually as common as you might think, even when London is the warmest region) the nearby sites of Northolt, St James Park, Kew, Wisley - and sometimes down to Charlwood- are there or thereabouts. I am pretty sure this is human intervention by the Met Office. I think when most apps search “London” they get Heathrow.

My point exactly on the date record thread. Qu (me):

This is very interesting because, as you say, 38 is forecast for Heathrow, and also for Kew, with 37 for Northolt.

Yet other locations in the area are forecast to be 5 or more degrees lower- for example, Wembley, Twickenham, Richmond, Kingston, Chertsey and London only 33; Staines 32.

All three locations are often hot spots and are all located within close proximity of each other. Perhaps a combination of urbanisation & local terrain play a part? The heat equivalents to say Braemar & Altnaharra are for cold?

Just another day then.

However, the text forecast goes against it - which seems unusual and presumably rules out human "tweaking" to the automated forecast?

"Another mainly dry day with some long sunny spells, although an isolated shower is possible later in the day. Very hot inland, but onshore breezes keeping coastal areas cooler. Maximum temperature 35 °C."
