The 12 month rolling CET mean now stands at 10.69C. 

The last major peak for this dataset was in November 2014 at 11.03C.

Of the last 48 months, 29 have been more than 0.5C above the 1971-2000 mean. Only 7 have been more than 0.5C below that benchmark.

England as a whole likely to see the second warmest Spring on record (behind 2011) since 1910. UK temperature as a whole should be in the top 5. Northern Ireland - warmest Spring on record.

Sunshine in the top 10 ranking by year and most places also drier than average.

So overall a very decent Spring indeed. Just a shame that a couple of late frosts caused some real damage for growers.

 

Provisionally I have the Spring CET at 10.25C.

Previous highest was 10.24C in 2011. So it will be touch and go. Depends on the extent of the final adjustments to the May CET. 

The Spring CET has only ever been above 10C on five previous occasions. Here are the top 6

2017 10.25C PROV
2011 10.24C
1893 10.20C
2007 10.10C
1945 10.07C
2014 10.03C

OK thanks GW. Very 50:50 then.

Yes, 13.21 the final answer. Congrats to Lanky!

And congratulations to Lanky for taking  the overall  lead to date!

Here are the charts for May. Another very warm month.

Spring as a whole finished at 10.27C which is the warmest on record beating the 10.23C of 2011.

For your amusement; this is how wrong GFS got the first half of May this year.

Even accounting for such typical bias I was still left expecting too low a CET return for that period... and then came the exceptional warm spell in the second half of the month.

Oh well - it's a nice way to be wrong
