Latest CET tracker for December shows a finishing number of 6.27C.


The CET mean for tomorrow (NYE) could get above 13C. The date record for 31 Dec is 11.1C set in 1859 so we will easily beat that. The all time December daily CET mean record is 13.1C set on 19 December 2015. We could get close to that tomorrow.

Highest temperature today was Cambridge NIAB at 15.6C


Yesterday was Exeter AP at 15.7C


Both days have a date record of 16.1C so we were fairly close.


Tomorrow the date record is only 15.6C so a very good chance it will be broken.

At least the new record (15.8, but I wouldn't be surprised to see higher after the 18z SYNOP reports) is non-contentious!

I'd have nailed this one if that cold spell had materialised.


Missed this one out by miles - went for 4.75C ended up over 6.0C

I think that means I win the annual CET competition as I predicted 10.32C!


You were second with 10.10C.
