The 1813 one is very interesting as that occurred just before start of the severe winter of 1813-14, it wasn't until the 28th of March 1814 before that daily CET value was beaten.

Pardon my asking, but where is 1987 in this chart? I recall we played cricket on the lawn that day in Surrey and I'm sure the mean would have been at least 8.0C that day.

CET mean  was 7.3°C  that day and therefore didn't meet the criteria.

London Gatwick recorded a maximum of 10.7°C but the minimum was only 3°C

Somewhat mild air aloft but the south was under a ridge so perhas people's perception of Christmas Day 1987 being very mild is somewhat warped by the fact that I heard that it was quite sunny, and mild, sunny weather in the first half of winter is fairly rare. Explains why the nighttime temperatures, while above average, weren't particularly mild.

2015 also, came in at bang on 8C mean.

One of the coolest days of that month!
