Sunniest Day: 5.6 (on 1/12)
Sunless Days: 10

Conclusion:

An absolute disaster of a so-called "winter" month which was completely snow-free without even a single flake of snow throughout the entire month.

It was a milder than average month with an abysmal number of official air frosts.

It was also slightly wetter than average both in terms of the actual rainfall amounts and in terms of the number of official rain days but in both cases, it was nowhere near as wet as it was in many other parts of the UK.

When we take the missing data for 9/12 into consideration, December probably comes out slightly sunnier than average as that missing data was probably enough to bring the total for the month up to above the 1981-2010 average as that was quite a sunny day, but we can really just say that December was a fairly average month in terms of sunshine.
