My calculation for the 25th was 11.4C which equals the 1846 date record. So will be touch and go whether the final figure breaks the record or not. But as you say very close to an all time record for January.

For the 27th I only get a figure of 10.7C but that is still a date record (current record 10.4C 2003).

My figure of 10.4C for the 24th is only 0.2C off the date record. 

So some very mild weather in the first part of this week.

Met Office Hadley                5.6c.         Anomaly     1.8c.    Provisional   to  28th.

Metcheck                            5.33c.       Anomaly     1.8c.

Netweather                         5.81c.       Anomaly     1.62c.

Peasedown St John              5.9c.        Anomaly      0.2c.    

Hmm I feel I could be close but a no cigar situation 

We now have the final data from the Met Office for daily temperatures in December. I have summarised below all of the date records for maximum and minimum temperatures in 2015. We had 9 records in November and December alone. There were several other days in December that came very close to date records. We also managed to beat the long standing date record for Christmas Day.

Here are the maximum date records for January. We have broken two of them this month.

This means there is now only one day in January where we have never recorded 15C - the 8th where the record is 14.9C.

Here is the winter CET tracker. I have added in for comparison 2013/14 (a recent very mild, wet and stormy winter) and 1868/69 (the mildest winter on record).

You can see that we are currently on track for the warmest winter ever. But we still need a relatively mild February to achieve this.

In order to beat 2968/69 the CET needs to average 5.2C for the rest of the winter.

Met Office Hadley               5.7c.           Anomaly          1.9c.    Provisional    to  29th.

Metcheck                           5.43c.         Anomaly           1.28c.

Netweather                        5.98c.         Anomaly           1.79c.

Cheadle Hulme Weather      6.1c.           Anomaly           2.2c.

Clevedon    Weather          7.4c.           Anomaly            1.0c.

Mount Sorrel                      5.6c.           Anomaly            1.4c.

Peasedown St John             6.0c.           Anomaly            0.3c.

My Annual     6.0c.   Difference   0.3c  NOAA  Monthly...  

To beat the seasonal record of 6.77 we need a sum of the 3 means to be 20.32. Assuming Jan finishes on, say, 5.7 that's 15.4; we need a Feb CET of 4.92 - although with Feb having fewer days the actual mean per day (not an official measurement I know) would require slightly less. 4.92 might still not be reached.

I did wonder about that - but February only needs to be a repeat of what we had this January which I wouldn't thought was too hard to get.

But February can throw up some surprises.

Nearly the same as yesterday.

Met  Office Hadley          5.7c.           Anomaly         1.9c.   Provisional to  3oth.

Metcheck                       5.39c.         Anomaly         1.24c.

Netweather                    5.98c.         Anomaly          1.79c.

There is also the very real possibility that this meterological winter could be warmer than the meterological spring of 2013!

The Met Office have updated the finalised value for January as 5.45C

http://www.metoffice.gov.uk/hadobs/hadcet/cet_info_mean.html

4 punters got 5.50 so well done to Devonian, Gezm, Duncan McAlister and Spring Sum Winter Dread - 4 yellow jerseys to start off the new comp for 2016

Also of interest the CET Mean for 25/01 has been revised up from 11.5 to 11.6C so it now is the equal highest January value for mean CET along with 23/01/1834 and 03/01/1932

Here are the final charts for January. Another very mild month.

However, we did have one decent cold spell. The 7 days from 15 to 21 Jan had a CET mean of 1.5C which is 3.3C below average. The other 24 days of the month had a CET mean of 6.6C which is 2.3C above average.

Overall the CET for this winter is well above the record winter of 1868/9.

As lanky noted above the CET mean for 25 Jan equalled the all time January record. 

Also the maximum CET of 13.7C on 24 Jan equalled the all time January record set on 9 Jan 1998.

I was a bit out with 6C. But not too bad really.

Annual CET competition - January update

Here are the first tables of the year. Congrtsatulations to pace setters including first timer Spring Summer Winter Dread (abbreviated to SSWD in the table for space reasons).

I should add that I have been very generous to start the year and have waived all penalties for late predictions in January. I will start adding on penalties for February onwards.

Don't know if you saw my PM GW about my name change.

I was ErghKommol, just in case you didn't.

Ah sorry yes I did see it but forgot to update my spreadsheet. Will update for all future tables.

thank you

Thanks for the table Simon. 

Thank you GW and congrats to all those on the top table for predicting so closely.  Lots of room for improvement for me though.

Oh gawd, another year of mid-table mediocrity beckons. Not for the first time, I was looking like getting it close as we moved into the second half of the month, only for the models to flip (away from cooler, towards much milder) conditions.

Bloody weather!

As the starter used to say to Franze Klammer "it's downhill from here"

Oh, you know you want to be generous with Feb as well, don't you! 

Thanks so much for your efforts on this!
