Hadley December 2009 CET is confirmed at 3.1*C, (3.10), which makes it the 18th coldest in the past 100 years.

I'm surprised the figs have already been posted, before they have taken a few days to round up or usually down

Why so quick this time ??. Anyway comes in at 99 coldest December out of 352 !

The adjusted figures also show that the 7 days 18-24 December inclusive were all below zero, the first full week of sub-zero CET days since the 12 in a row of Feb 1991.

December 2009 is the first month to be 2.0c below the 71-00 and 1.5 below the 61-90 (actually 1.6) this century and is the biggest negative anomoly this century and against the prevailing 30 year average since May 96 (2.1 below the 61-90 average) and for a winter month since Dec 95 (2.4 below the 61-90 average)

18-24th December = -1.09C

First time five or more consecutive sub-zero CET days have occurred since January 2001. Quite a run!

Latest CET results in and a big well done to Terminal Moraine who got 3.1 spot on, North Sea Snow Convection was 0.1c out and Polar Side was 0.2c out.

From that you can probably guess it was a cold month.

Thanks again Jackone for a fantastic job with the results.

I don't have the figure to hand (because the metoffice is slow at releasing data) but provisionally Scotland and N.Ireland has had its coldest December since 1981! (beating the frigid 1995)

Wow! Didn't expect them to have had a colder December than 1995!
