February got progressively colder until 15th, with significant frosts 9th to 14th, and snow from late evening on 7th until the 11th. After that it became milder, so the overall temperatures were nearly normal.
Rainfall was above average, with 7th highest number of raindays and 9th highest number of very wet days (in 66 years records here).  The first and third weeks of the month were wettest, and the 2nd and 4th fairly dry. A quarter of the month's rainfall was on the 1st and 2nd .
It was dull for much of the month with occasional sunshine, the best proper sunny days were from 25th to 28th. It was windy at times, especially from 18th to 24th, the highest windspeeds being recorded on the 23rd.
So after a wet start to 2021, at least the end of February brought better sunshine and a breeze which has started to dry out the the top layer of the soil in the garden!
