So what was the Hadley final figure.

Met office figure for May    13.3c.    Adjustment   of -0.2c. 15th Warmest on record.

That's pretty impressive.

13.25C in fact. http://hadobs.metoffice.com/hadcet/cet_mean_2018

Congratulations to redmoons who had the closest prediction this month with 13.20C.

The combined April / May CET is the equal 6th warmest on record

2011 12.00C
1892 11.70C
1798 11.65C
1865 11.60C
1788 11.60C
2007 11.55C
2018 11.55C

Despite the very cold March we still had the equal 40th warmest Spring on record. 2017 is of the course the warmest on record.

The warmest Apr / May / Jun CET averages are as follows:

1798 13.40C
1762 13.27C
1775 13.00C
1893 13.00C

To reach 13C this year we would need a June CET of 16.0C. To reach 13.4C we would need a June CET of 17.1C - i.e. we would need to beat 1976 by 0.1C.

There is every chance we could do that this year. Agree May was absolutly fantastic about the best the uk could ever hope for.Both bank holidays being scorching with plentyof sunshine. I wonder how long it will be before we get another bank holiday weekend like the last two,they certainly made up for the grim easter.

It seems like we bypassed spring this year one week the max temp was in the low teens then a week later it was in the mid 20`s.

Summer came early this year lets hope it doesn`t end early.

Warmest May since records began 100 years ago.

I must say I'm surprised at this.

Bear in mind they are only talking about maximum temperatures here not mean temperatures. 

For the CET series the maximum CET for May was 18.9C which actually is just short of the 19.0C set in 1992. The CET Max series goes back 140 years. The UK series goes back just over 100 years and for the UK as whole 2018 was just ahead of 1992.

Agreed; I posted a challenge to this slightly sensationalist Beeb coverage on the media thread the other day.

The CET is a more robust (over 300 years) and representative figure I would argue for England as a whole but, as you say, the key point here is that the maximum alone is not the best indicator of the warmth of the month as a whole. 

Here are the charts for May and Spring

A very warm month in May and overall Spring came out above average despite a very cold start.

Huge deviation between the maximum and minimum anomalies this month. Maximum CET more than 2.5C above average and the second warmest on record. Minimum CET only 0.5C above average and that was due to a very warm end to the month.

Annual CET competition - May update

No change at the top as Darren S remains well clear with Stormchaser in second. Snoeshoe moves up to third with Gusty remaining in fourth

Not completely ashamed of my 12th out of 45; hopefully I'll nudge up a bit in June? 

The only way is down. 

I’m happy to hang on in the top half of the table - just!  

Cheers GW, only just realised as I just got back from holiday. Stunning month after the cold winter :)

You are a consistent good predictor in this competition. You have proven your skill in this competition, having won it back in 2014/2015 ?

A runaway leader and hot favorite to take the 2018 title at this stage.

Thanks Steve, and Caz.

I'm wondering whether anyone has led the competition in a given year from April right through until the year end before? In my mind the lead seems to change hands quite a few times most years. It will only take one duff prediction to slip up, so I think staying where I am is quite a tall order.

No they haven't. But the year you won Darren, in 2014, you went top in June and after dipping to second in July went back to the top in August and stayed there until the end of the year.

Nemi was also at the top from August to December in 2013.

In 2012 Brummie Snowman went top in April and was top for 6 months between April and December, dipping to 4th in May and 2nd in October and November. That is as close as anyone has come to being top from April through to the year end.

I echo other posters comments regarding your consistency, and would add that you are in a very strong position and can afford to not take too many risks - while your competitors will need to take risks,  to just catch you, with all the attendant probability of guessing the "wrong way".
