needs updating.


The 28 June 76 max CET of 30.3 was beaten last year (30.6 on 29th June)


Incidentally, the July max record also went on 25th last year (34.1), so that also needs updating from the 33.2 stated, also in 1976. 



Good spot Bert !


It looks to be as though this is a "dead" page from a Met Office point of view as it has a last updated date of 2012 on it and it doesn't seem to have any links into it.


The data it shows is quite interesting, however, and can be easily recalculated from the daily CET files they still maintain as shown below


The updates since 2012 have all bar one been in the Max's area apart from the "Beast" of March 1 2018 and these are in red


No Minimum Mean CET has been beaten for any month for over 100 years !

Plugging in the GFS 00z numbers gives a final provisional CET estimate of 15.5°C. Adjustments may then knock a few tenths off that.


June came so close to being a warm month overall. Tropical cycles pushed it in that direction last week but it was not a strong enough push for prolonged 'high summer' weather.


Now, we wait in hope that the next push, taking effect next week, will achieve more. In the meantime, a very changeable week ahead and signs of another difficult weekend for outdoor plans.


We're not on a 2012 or 2007 path but instead something more typical of a more unsettled type summer. Those two years were exceptional.

It'll be interesting to look at the final scores for temperature, sunshine and rain and then place this in the summer index. My feeling is that whilst it's been a bit warmer than average, it will also have been marginally duller and a fair bit wetter. So a mediocre summer month salvaged by a very hot spell towards the end.

Indeed the fifth summer month in a row that meet the criterion "mediocre summer month salvaged by a very hot spell towards the end.

It does seem to be very common for a so so June to be massively uplifted by a late heatwave.
How cool would Junes 2011, 2015 and 2019 have been if you removed the final week from each ? Alot cooler than they ended up that's for sure

Thought August 18 had its heatwave at the start Tim?

Yes it did. I was getting confused with last year. The stats I showed on the moaning thread show this - first week.

Pretty sure that makes 6 consecutive months where I have guessed too low! Think I might need to check the algorithm.

Here are the Met Office charts for June


Temperature


Warm just about everywhere


Mean temperature https://www.metoffice.gov.uk/pub/data/weather/uk/climate/anomacts/2020/6/2020_6_MeanTemp_Actual.gif


Mean temperature anomaly https://www.metoffice.gov.uk/pub/data/weather/uk/climate/anomacts/2020/6/2020_6_MeanTemp_Anomaly_1981-2010.gif


Rainfall


Wet in the west, drier in the east and south-east. Many places saw average or above average rainfall. Western areas, especially the SW of England were anomalously wet. Only the far SE of England and Orkney and Shetland were much drier than average.

Rain anomaly https://www.metoffice.gov.uk/pub/data/weather/uk/climate/anomacts/2020/6/2020_6_Rainfall_Anomaly_1981-2010.gif


Sunshine


Most places average or below this month. Exceptions were East Anglia, Kent and Shetland.

Sun anomaly https://www.metoffice.gov.uk/pub/data/weather/uk/climate/anomacts/2020/6/2020_6_Sunshine_Actual.gif


It seems to have been a rather nice month in Shetland.


Lerwick had 151 hrs of sun which is 118% of average and 31mm of rain which is 53% of average.


Shoeburyness was the sunniest place this Spring in the list I posted in the Spring sunshine thread (although not the sunniest as I think it was confirmed that the Isle of Wight broke 800 hours).


Shoeburyness tops the list of SYNOP stations again for June with 249.4hrs of sun. This means the station has now recorded a phenomenal 1,045hrs of sunshine in the past 4 months. 


Looking back to the earliest months of the year Shoeburyness managed 103.6 hours in February (second only to Aberdeen Dyce that month which had 125.4hrs). 65.4hrs were recorded in January.


So Shoeburyness sunshine total for the first 6 months of 2020 is 1,214hrs. Not bad really! Surely it must be on course to smash the annual record if it keeps this up.

I very much believe the CET does not show the whole story of the month, bring skewed by 2 or 3 hot days, the rest being average or below.

England and Wales stats: 14.9C, 95mm, 182hrs sun. On my summer index that scores 124.93 making it 25th out of 49 so mid table. Much lower than May (153), only a little ahead of April (120).

Thanks for that stats roundup GW .


Some truly amazing sunshine totals there. More modest where I am but still as sunny as I've ever known, 966.2 hours in the past 4 months and 1084 hours for Jan-Jun 2020. This despite June being extremely average with 99.7% of the normal hours.


 


The short but potent hot spell, setting two date records here, had a dramatic effect on the June-to-date temp anomaly (v. 1981-2010), which rose from +0.02°C on 23rd to +0.71°C on 26th.  However, a cool finish then mostly countered that with the anomaly to 30th coming in at +0.19°C.


I imagine it may be a similar story for the CET when comparing with 1981-2010 (as severnside implies), as opposed to the 1961-1990 baseline that's displayed in the current year Hadley CET stats.


 


Looking at the model projections for the next 10 days or so, I wonder if July 2020 might display a similar tendency to be mainly near average but with a few markedly warmer interludes. Much depends on the 2nd half of the month, when several sources including the Met Office and the CFSv2 long-range model are keen on breaking us out of this pattern, with some longer warm spells developing.

5.5c!? I hope you don't mind me saying but I think that's a tad pessimistic for June, even in the UK
