Proof we did see very mild winters in days of yonder, in an era without 'global warming' - quite a remarkable season that one. What happened in Spring 1869?

Really topsy turvy.

March was cold :3.8

April was very mild: 10.1

May was chilly with 9.6

May colder than April.

As you know, it was the mildest winter of the 360 years in the CET records. Dec was 7.2, tied 12th warmest, Jan was 5.6 which was tied 33rd warmest and Feb was 7.5, 2nd warmest. However, the winter of 2013-2014 came close to matching that at the lower end -- Dec 2013 was ranked tied 35th while January was tied 30th and February tied 31st. 

The summer of 1976 had three months that beat the performance of winter 1868-69 though, both June and July were 4th warmest on record and August was tied 12th warmest. The summer of 1826 also beat winter 1868-69 for "ranks all better than x" with tied 28th (July) being its least warm ranking. June was 3rd and August was tied 12th.

The best spring in terms of staying above a given rank was 1893 which managed tied 38th for March, tied 6th for April and tied 20th for May. 

And the best autumns in this regard include three that outdid winter 1868-69 for staying above 33rd, these were 2011 and 2014 (both had tied 19th in September as their least extreme ranking) and 2006 with 24th (for November).

Hope I didn't confuse readers here, I was thinking, "what do you call the least extreme, a high rank or a low rank?" ... could not decide, to my mind, a "high ranking warm month" would be 1st rather than 33rd. So I settled on "least extreme" as my wording.

Since I had this file open, I could mention that the "all colder than" measurement would be winter 1683-84 where December was tied 11th coldest, January 2nd and February 6th coldest. For spring, the coldest set was in 1887 where all three months were at least (tied) 32nd coldest, then for a dire summer we go to 1725 (worse than 1816 or 1912) which managed to stay top ten coldest (9th June, 7th July, 4th August). The autumn candidate is 1786 where September tied 28th coldest, October 18th and November 8th. 

By the way, if anyone from Hadley looks in, your current version of the monthly ranking table (CET) has a glitch -- there is a phantom 0.0 added for each month with a ranking. This alters the rankings at the cold end of the table (and gets into the action of the winter months). Here's the link, I have tried to get my rankings accurate after removing those from consideration.
