Met Office Hadley Center CET

18.2c      Anomaly     2,2c provisional to  19th.

Minimum yesterday: 18.9

Maximum: 37.3 (!!!)

No mean released, but my maths says 28.1. Hottest day ever by 2.8C!

I am not sure how they got 37.3 because the mean of the stations was 37.2C and then it is supposed to be revised downwards by 0.2C isn't it?

Mean has also been updated on the website to 28.1C, as you calculated.

Is that a record for all three then?

That minimum, if it is retained, beats the highest 2 I can see in the series by 0.1C: 29/7/1948 and 11/8/1997 - 

unless anyone is aware of other higher values- I checked 2018,2006,2003, 1995, 1983, 1976, 1975 (3rd I think with 18.5 on 5th)

A search of https://www.metoffice.gov.uk/hadobs/hadcet/data/mintemp_daily_totals.txt gives the follow 18.x figures:

1948-07-29   18.7

1949-09-05   18.4

1975-08-05   18.5

1997-08-11   18.8

2001-07-29   18.3

2004-08-09   18.5

2006-07-26   18.0

2020-08-12   18.5

2020-08-13   18.0

2022-07-19   18.9

but also....

2016-07-20   19.5

So July 20 2016 seems to be the record minimum, if that is accurate.

Another great analysis Rob; thanks. Didn't think of 2016 but I remember now that was our Sports Day- absolutely blistering evening.

Yestrday's provisional CET max was 37.3C and (apart from yesterday's 34.8) beat the previous record max of 34.2 by over 3C

In stats terms that is just about 1 sigma (1 standard deviation) more than the previous outlier (from about 4 to 5)

In terms of return periods that is a huge difference and despite the dire forecasts of climate change I doubt there will be anything to match this CET max for a very long time to come (probably not in many of our lifetimes)

There may well be more regional records broken but the CET covers such a broad swathe of the country

That was a very hot day as well so surprised the CET wasn't a record breaker

July 19 2016 was a 30.9 CET max - the real heat was confined to the SE with Wisley hitting 36.4C.

Metcheck           18.71c       Anomaly      2.24c

Netweather        19.4c         Anomaly      2.91c

Peasedown St John   10.01c   Anomaly    1.71c.

Yes as I just noted in another thread, that CET max would have been a new UK temperature record on its own before 2003!

18.3 CET to 20th.

Edit: also interesting that 19th July was the heat peak in 2006 as well.

CET prov (hopefully not too prov now they've changed the system) 18.2°C so back a pip.

This month has been quite remarkable locally.

I have not recorded a maximum temperature below 21°C and that temperature was on the first. It was 22.9°C on 5th and every other day has been >23°C. Yesterday was the first day < 25°C since the 7th. There have been 8 days of 27°C or more.The first week had fairly cool nights but the rest have been above average. Highest max however was a (comparatively) modest 33.1°C.

Hadley

I wonder where we are now.

I wonder where Art is?  

I wonder where Art is?  

I was thinking the same.

I wonder where Art is?  

I always look out for Arty on the daily CC and monthly rainfall threads, but I have also just noticed he has posted anything on either or those two threads either in recent days that I know of.

Hopefully, he will just be enjoying a well deserved break and is perfectly OK.

If that is the case, I'm sure that he will be back before too long, all nice and refreshed from that (albeit, with him making fewer of his famous typos as a result).

I wonder where we are now.

Only up one notch, 18.3C to the 24th.

Another 0.1C would put us in the top 10 Julys, joint 10th with 1757 and 1808. A 0.2C increase would tie us with 1976 (don't tell GB News!)

I see that since the Hadley figures were revised, July 2006 has gone up to 19.8C. It used to be 19.7C.
