Yes, however that is not what Rob was asking. He asked if it was 34.9 or 35.0 and not 34.9 or 35°C.

In that case, it might be possible to check that at somewhere like ogimet.com or weatherobs.com if that is a major station (even if that is one with a prefix which starts with 99 rather than 03, that might still show up at weatherobs.com).

That would then help to remove any confusion and clarify the situation.

EDIT:

I've just did that check myself and according to Meteomanz, Charlwood is a major station with a WMO code of 03769, so it should send out detailed SYNOP/BUFR codes similar to what goes out from Gogarbank here in Edinburgh.

Yesterday's maximum temperature was sent as part of the raw SYNOP code that station for 18z, and went out again as part of the 21z raw SYNOP code.

That raw SYNOP code shows that yesterday's maximum temperature at Charlwood was actually 35.0°C even to the nearest 0.1°C, and not 34.9°C.

I had done before posting, although somewhat ironically it has been update to 35.0°C since then.  The SYNOP report below is for Charlwood.

Indeed 26c already at my nearest WS Stansted.

That's weird since I've never known of any raw SYNOP data to be altered at such short notice, or even at all.

I guess that it that can happen at Charlwood, it can also happen at somewhere like Edinburgh Gogarbank as well, so that is something else to look out for when I'm compiling my own monthly or seasonal statistics for there, as these changes can add up to quite a significant difference in those actual statistics if this was to happen on a regular enough basis.

It's good that we have those 21z (and 09z) reports though.

That is something which was only fairly recently added to the available data from ogimet/Meteomanz whereas previously, you only got the minimum temperatures at 06z and the maximum temperatures at 18z from that data, whereas the official observation day as defined by the UK Met Office is usually from 09:00 UTC (which is either 9am GMT or 10am BST depending on the time of year) on one day to 09:00 UTC on the next day.

Because of that, I would probably say that the minimum temperature as obtained from the 09z report along with the maximum temperature as obtained from the 21z report are probably more likely to be in line with the values for that, which are then officially recorded and reported by the Met Office (although I could well be wrong there of course).

Last night was perhaps the most uncomfortable of the summer, felt worse that last month, perhaps because the humidity is rising. Will be a welcome relief when this ends now

A tad cooler than yesterday so far at the vineyard. I think today will be better in the Midlands and North of London compared with recent days. More of a Southerly flow. 

EA has quite a few 31s at 11am

Some 32s but temps seem to  be plateauing somewhat already. We have cloud bubbling up here as well first for awhile. 

Cavendish 33.4c is the highest 1pm I can see. 

Whatever happens now, this will be the best August since 2003 here. Hopefully a few sparks over the next few days (though I'm not holding my breath) and hopefully another warm and sunny spell later on would secure it as the best since 1995.

Be very interesting how this August pans out. If this nice weather runs through the August Bank Holiday then I think we should have a nice September.

Indeed. I certainly wouldn't rule out another heat wave in September. Given the current state of things, I'd say the chances of a top five September for warmth are higher this year than in a more typical year.

A hot August BH weekend would just perfectly round off this month, though.

I used to love hot weather in my younger years. But I really am fed up with this heat now, as it’s just energy sapping, so the days are not useable.  I have so much to do but it’s just too hot.  

A remarkable summer indeed, and quite possibly the first to have two months above 18C in the CET since 1995. Indeed a kind of hybrid of 2003 and 1995 in many ways. 

A hunch (and a few other things - the SSTA pattern, the phase of the solar cycle, the warming trend, the better state of Arctic sea ice and so on) tells me perhaps we have seen a secular shift this year and we could see several hot summers in the coming decade. And several very mild and possibly dry winters. A dry winter followed by another 2022 spring-summer = 1976 revisited. Let’s see. But Europe has already seen the shift. It just seemed to be muted in Britain by multiple summers of southerly tracking jet and Greenland high.

We will pay for this prolonged dry spell for sure.

Hot weather loses its appeal very, very quickly. I can't wait for this endless, endless summer to end. 

The only good news really is that we're losing 3 and a bit minutes of daylight a day, so it gets increasingly harder to sustain the really unpleasant temperatures for very long. Several days with dewpoints in the high teens / low 20s is utterly sapping! And to think, it used to be 17 or 18C DPs that were as high as you would see... it's as if we've all moved a few hundred miles south.

I wouldn't mind as much if it was followed by a 1995/6-style cold spell at Christmas (the last widespread White Christmas in the SE of England with snow falling and settling was 1970), but there are two downsides to that thought: one, it's clearly not going to happen, as it never does and two, if by some fluke it did happen, although I'd be dancing with happiness I know most people would be the exact opposite, for a variety of reasons.

I do wonder, though, whether given the atmopshere's tendancy to get "stuck in a rut", how many more plumes we'll manage to import before it finally becomes cold from the mainland of Europe, as opposed to hot...
