It would be interesting to know what the high at Humberside airport was. It has been reporting 40C on the METARS for a couple of hours now.

Cambridge botanical Gardens is potentially a challeneger because you won't know about it until tomorrow. It could have had 40.5 earlier today but we won't know. Same for Brogdale. I'm not talking about current temperatures. It's done now.

However, that is in line with what we had here in Hawick, so that looks like a perfectly valid record to me.

Charterhall is on the main list of stations which is normally found at weatherobs.com, and is one of the stations which I always refer to as one of the nearest stations to where I am here in Hawick, although I haven't been able to find any data for there recently.

Perhaps, that might be the reason why there might be some doubt in that data and why it needs to be verified.

Any final result from Doncaster yet? It reported a rounded 40c a couple of times but no clue if it actually breached that figure. 

Could be 3 if the airport counts

I don't think we can ever see the exact figures from airports unless the Met tweet them out.

yay, it's working after all! Result!

Sound, thanks!. That's a pity really. 

Actually kind of dissapointed. I didn't really expect 42C because of the sparsity of the stations, but I did expect at least one 41C

When I was outside in the shade I went up to 40.5C, I'm quite suprised nowhere has managed to get beyond 40.3C

No, just the Botanic Garden, Cambridge NIAB is in the nearby village of Histon and in 2019 measured 0.5C below the Botanic Garden's record of 38.7, so if the same happens again the Botanic Garden would give 40.4C.

If we will see this again in our life time or not long to wait for next time.  Today was the day we attempted to get to 40C after some attempts failed from 2015 onward.

35C and hazy sunshine, humidity going up also.

Humidity rising making it feel hotter than any other point of the day so far.

I think the sea breeze screwed us.

The hot land caused winds to become more easterly near the coast, while the front caused westerly winds further west. The result was a convergence zone which not only promoted cloud development but ascent that mixed some of the hotter air out of the boundary layer.

The GFS didn't pick up on this convergence zone, and while the UKV did it was further north in North Yorkshire.

That seems valid and in line with today's maximum temperature in Hawick since that is the nearest station to there.

The temperature has now dropped a bit and although it's still 29°C here as I write, it actually feels quite cool in comparison, and I'm not sweating as much as I was earlier on.

Yay!

It was bound to be hotter than 32.9 somewhere near the border

Carlisle got up to 34.4 (nd might have been higher in-between the hours) and I know the weather station used there is at the ex-RAF facility in the north of the city only 5-6 miles from Gretna across a flat plain near sea-level as the crow flies, so I reckon Gretna would have recorded the same figure +-1C

Carlisle used to belong to Scotland so we can just claim it directly too

Only Northern Ireland misses out on its record then.

I mean credit to Brian for calling the temperature as being somewhere between 39.5 and 40.5

I can't even really take credit for my 40.2C prediction in the competition thread. I just forgot to change it, I would have gone higher.

I think it's mightily impressive for a small island. 40 was always a huge step yet it has been breached and that relates to a warming world.

However i think the huge increases modelled earlier are unlikely. Whilst i don't doubt 42 - 45+C isn't possible with some model runs showing them recently it does take a real aligning of all variables and probably is a 1/1000 year event such as the Canadian heatwave. Even more so in our climate where we are so close to the sea and not large land mass

I got it bang on 40.3 but went for Cambridge, fingers crossed for the Botanical gardens figure. 

I thought the weather station was near huntingdon Road and not the farm near Impington/Histon only a mile or so difference anyway 

Long wait to see what botanical gardens show in the morning.

So are we just waiting for Cambridge?

Is there no chance of a lincolnshire site getting upgraded?

According to the Weather App, Sheffield topped 40 C. Certainly felt very hot but strangely not oppressively so; must be very dry air. Felt strange to have gusty winds, too, it certainly felt like being in Australia.
