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!

A
very dry month, ranking 4th lowest in last 66 years, with
precipitation predominantly 1st to 3rd, 19th
to 12th, but most falling on 26th, 27th
and 29th . Snow
was falling or lying on 27th to 29th. Mean
temperatures were overall only slightly below normal, it was milder 9th
to 20th, but colder 22nd to 29th.
Windiest days were 26th and 27th as storm ARWEN
passed the east coast.
Brightest days were mostly 1st to 5th, less so 7th
to 9th and 17th to 19th.
So not a very nice end to the month with the snow and wind, although
otherwise the month had not been that bad.
