Surprised to see it drop again.

Must be the cool nights.

Oddly when Hadley was last at 16.0 a week ago Metcheck was at 15.59 and 10 station mean at 16.22. So the others have risen while Hadley CET has gone down then up to the same place. Suggests the downward adjustment at month end may not be so big this month.

Just another 0.2C to stick us in the top 10 Junes.

I was hoping that June may settle at 16.5C, which would give it tenth position all by itself!

Just anyone have stats for July at hand? only 48hrs to go till July kicks off ......year is flying!

Mean Temperature Of My 10 Watched Stations   17.06c.          

I've got an idea what I'll go for when Simon puts on the July CET watch.

So uh... I used the ECM raw numbers to estimate what the 00z run did for the CET. 

It sits in the 20s for 1st-9th. That's an impressive start, but GFS continues to produce some much lower temps for the middle part of next week due to more of a HP circulation to the N/NE bringing drier air back into play plus some low cloud at times, really holding the temps down for the east of the triangle.

UKMO 00z sided with ECM so I see that warmer outcome as the favourite - but temps might not get quite so high of the diurnal shower potential is being underestimated (there's hardly any on the 00z ECM run).

Oh and - the raw ECM numbers for my location place my mean at around 22*C for the first 9 days. That's not far off the sort of weekly mean I saw during the hottest spells of July 2006! 

The minimum CET for June is provisionally 11.4C which is 1.4C above the 1981-2010 mean

The maximum CET for June is provisionally 21.4C to yesterday which is 2.5C above the 1981-2010 mean.

The maximum CET could end up the 4th highest on record. Still way below 1976 though.

Here are the years with a maximum June CET of 21C or more:

22.6C 1976
21.9C 1940
21.7C 1970
21.4C 2018 (prov)
21.3C 1899
21.2C 1960
21.1C 2003
21.1C 1957
21.0C 2006
21.0C 1896
21.0C 1893
21.0C 1887

July thread coming shortly.

Thanks; an interesting league table GW.

That tallies well with mine for that period SC: w/c Monday 17th July 2006, through to and including Sunday 23rd- mean maximum 28.5, brought down by a slightly cooler weekend; and mean minimum 15.7 (with some hot nights 19th-21st). 22.1 the mean, pretty well maintained for the few days afterwards too with just a 0.3 drop until the following Friday.

The combined Apr - June CET for 2018 will be the 3rd warmest ever and only the 5th time that the CET for these 3 months has reached 13C

Highest Apr - Jun CETs on record:

13.40C 1798
13.27C 1762
13.16C 2018 (prov)
13.00C 1775
13.00C 1893

It's a real surprise that the other four leading values should have been set so long ago.

No doubt partly (or mostly) due to the hottest Junes occurring before the twentieth century. Top four hottest Junes are 1846, 1676,1826, and 1822. I would like to know what on earth was going on in 1846 with a CET value of 18.2C? 1976 at 17.0C was ridiculous enough but 18.2C in June must have been amazing. Put in context, June 2018 may come out at around 16.4C but that again is totally eclipsed by all these pre-20th Century Junes.

Interestingly, of the three summer months, both July and August all hold the top records for the CET series in recent years, but June still lags far behind in the CET series league table as far as Junes in recent years are concerned. I often wonder why that is? 

Final June figure is 16.10C

Several people, including myself predicted this figure.

Congratulations to Norseman, marting and Devonian

My perception is that the seasons seem to have shifted a bit later in recent times, with the coldest winter weather often coming in late February and March, and "Indian summers" often having the best weather after a poor midsummer. Of course the trend for warm Aprils and Mays sort of messes up that theory, but June (and August) have often been poor in comparison recently.

Final official maximum CET for June is 21.62C so fourth place it is just behind 1970 but still 1C behind 1976.

Minimum CET was 10.59C which put it in equal 20th place
