A
lovely dry, warm and very sunny month with the middle of
the month dominated by anticyclonic conditions. Mean
temperature 0.1C higher than Feb 2007. Normally dry and
sunny Februaries would have been associated with cold
conditions, but not with this month.

10C. There was a high incidence of clear, calm starry
nights which led to many grass frosts (20 in total) but
only 4 air frosts. |

average with only 46% of the normal. There was a notable
dry spell when rain failed to fall for 20 consecutive
days from the 6th to the 25th. |
There was no snow lying or
falling at any point in the month, nor was there any
hail, thunder or fog. |
Sunshine levels were
above normal. No cloud was seen at all from the 9th to
the 14th. The 18th recorded 9 hours & 44 minutes of
sunshine, this was 95% of the theoretical maximum
possible for that particular day. |
Soil temperatures remained
relatively constant throughout and the month and were
above normal. |
This was generally a calm
and settled month though the month did start windy with
gales on the 3rd. Light wind conditions prevailed from
the 7th to the 20th. |
Only 34.8 hours had
temperatures below 0.0C despite the prevalence of calm,
clear nights. |
Sea temperatures remained
above normal throughout the month. |
Mean pressure was 6.9 hPa
above normal. |
Notably low dewpoints
caused by dry air from the nearby Continent. |
With a relative humidity
of 76%, this was 10% below normal. |
