Mine too

There is an option in the settings to show amateur stations from the CWOP (citizen weather observation programme). My screenshots above  had that turned off.

My goodness, you then realise how sparse our network is.

2 in east London is an utter joke and so sparse in some of the other regions expected to be hottest.

5pm (1600Z) update:

Cambridge 38c (r)
Lakenheath 37.7C
Santon Downham 37.5C
Mildenhall 37.3C
Cavendish 37.3C
Brooms Barn 37.1C
Stansted 37C (r)
Norwich 37C (r)
Jersey AP 36.9C
Coningsby 36.8C
St James's Park 36.7C
Marham 36.2C
Wittering 36.1C

Guernsey 34.1C so very close to the record

Here 34.3C a new high for the day and still going up

Just climbed up to 33.6 C.

Again, this is based on my vantage davis station perched on a pole atop a concrete wall so it's probably off - but then again I thought it was under reading earlier on today.

35.3c high here, smashing previous record by 1.2c. Dropped a bit when a chunk of cloud came over but now sunny again and 35.0c.
Leeds uni 36.7c high. If there was an official station in Leeds still you would think 36c or more was reached , especially as rural Bramham was at least 35.9c.
.

37.9C seems to be the final max for Jersey

Surprised by that - probably a record CET day though!

Some areas may still peak in the next hour or so. There is also the possibility of heat spikes between the hourly records that push it over 38.7C but I think we'll come just short today

We probably had too much ground to make up after a relatively cool night. Amazing that we've even come close considering that. The widespread heat today has been truly remarkable. 

Maxed at 25.9C here which is in no way noteworthy but was 4C above the forecast despite a period of unforecast overcast spoiling things during the morning.

If it's the same tomorrow then the record will be smashed but at least it's looking likely the ridiculously long period of 16 years without a 28C reading will come to an end.

Santon down to 37.5C

Looks like the record might have survived.

Still creeping up here - currently 32.3c

Booo!  Imagine if it doesn’t go tomorrow either. Talk about an anti-climax!

Are we still on for a hotter day tomorrow?

My ammeteur cambridge proxy is down to 36.6C from a high of 38.8C earlier

Genuinely think the record might have survived. Not much left now in the tank.

Derrylin 30.9C very close to the N Ireland record of 31.3C set almost exactly a year ago

Will definitely go tommorow.

But it will be somewhere in Yorkshire or lincolnshire.

Cambridge may have lost its day in the sun
