December 2009
A cold month overall having the 10th lowest December mean temperature here in the last 54 years, the coldest since 1996.
Although mild from 5th to 10th, mean temperatures were well below normal for the rest of the month,
especially between 18th and 24th.
Air frost occurred on 10 nights, and ground frost was observed on a further 6 nights.
Precipitation was 79% of normal, half of this falling before 10th.
Snow totalling 2.5cm fell on 3 days, but our locality was spared the problems experienced elsewhere, even though there were significant falls not too far away. Snowfall on 19th did not thaw until 26th.
It made a change having lying snow on Christmas Day, not seen since 1981.
