February 2009

The averaging period used for the following assessment was 1971-2000.

UK overview

A cold first half of the month followed by a mild second half resulted in mean temperatures for the whole month being close to the 1971-2000 normal over most of the UK. Temperatures over Northern Ireland and parts of north and east Scotland were slightly above average, by about 0.5 °C, whereas in parts of south-west England they were 0.5 °C below average. Rainfall was well below average in Northern Ireland, Wales, and western Scotland, all of which had the driest February since 1993. It was also much drier over much of western England. In contrast, rainfall was above average in East Anglia and parts of south-east England and eastern Scotland, largely due to the snowfalls early in the month. Sunshine was generally below normal across most of the UK, and it was the dullest February since 1998 over Scotland and Northern Ireland and the dullest since 1993 over England and Wales.

A maximum temperature of 16.2 °C was recorded at Faversham (Kent) on 27th. Aviemore (Highland) recorded a minimum temperature of -18.4 °C on 9th. Deancombe (Devon) recorded 52.8mm of rainfall on 9th. Balmoral (Aberdeenshire) recorded 42 cm of lying snow at 0900 UTC on 7th. A wind gust of 67 mph was recorded at Needles Old Battery (Isle of Wight) on 10th.

Sunshine duration was below normal; it was the dullest February since 1993. Rainfall varied from well below normal over north-west England to above normal over parts of East Anglia and south-east England.

1st to 7th: It was very cold during the first part of the month with snowfalls in many areas. This was the most widespread snowfall as a whole since February 1991. Frequent snow showers affected many eastern areas on the 2nd, especially south-east England where 15 to 30 cm accumulated in parts of London and the Home Counties. In the evening the heaviest snowfall moved northwards into north-east England. On the 3rd there were further heavy snow showers across south-west England. Overnight there were some sharp frosts in places with -9.6 °C at Odiham (Hampshire) and -9.4 °C at Mickleham (Surrey). On the 4th, a band of rain moved up from the south during the evening, turning readily to snow as it moved towards the Midlands, with 16 cm of snow at Upper Lambourn (Berkshire) and 11 cm at Boscombe Down (Wiltshire). Overnight on the 5th/6th a slow-moving front spread initially rain, which turned to snow across south-west England, and many inland areas recorded 15 cm or more. On 6th, places across southern England were very cold as temperatures struggled above freezing, with 1.7 °C at Writtle (Essex). The 7th remained cold, but was mainly dry with sunny spells.

8th to 16th: A mixture of rain, sleet and snow spread eastwards on 8th and further rain moved in to southern and central areas during the 9th. Overnight and into the morning of 10th wet and windy weather moved eastwards across southern England, with snow over the higher parts of the west country. Gusts of 40-50 m.p.h. occurred and the combination of rain and thawing snow led to flooding in places. The 11th saw sunshine and wintry showers. On the 12th snow gradually spread southwards across north-east England at first, then East Anglia and south-east England, with accumulations of 5 to 10 cm locally over higher ground. Daytime temperatures were very cold or cold across eastern parts of England, with maximum temperatures of 1 to 3 °C.

It wasn’t until the 16th that daytime temperatures rose above 10 °C.

17th to 22nd: High pressure was established in the second half of the month bringing milder and generally dry conditions for all, although mainly weak fronts brought occasional light rain and drizzle to many parts at times. Generally mild, with a top temperature of 13.3 °C at Boscombe Down on the 22nd.

23rd to 28th: A mild period with temperatures generally above the monthly average. Little in the way of any significant rainfall. The 27th was exceptionally mild with temperatures around 15 °C in the London area; 15.4 °C was recorded at Kew Gardens (Greater London).
