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!
