UK overview

March was quite a contrast to the three wet and stormy winter months which preceded it. At times, the weather was dominated by high pressure, particularly around the middle of the month, and there were several warm days giving an early taste of spring. Some areas, most especially western Scotland, did have wetter weather at times.

It was another mild month, with the UK mean temperature 6.7 °C, which is 1.2 °C above the 1981-2010 long-term average, and the number of air frosts was below average. The UK overall received 85% of average rainfall: East Anglia was the driest area, and only a few small areas exceeded their monthly average. It was sunnier than normal everywhere except the west of Northern Ireland; the UK overall received 127% of average sunshine hours.

A maximum temperature of 20.9 °C was recorded at St James's Park (Greater London) and Santon Downham (Suffolk) on the 30th. A minimum temperature of -6.8 °C was recorded at Redesdale Camp (Northumberland) on the 24th. In the 24 hours ending at 0900 GMT on the 20th, 78.8 mm of rain fell at Cluanie Inn (Highland). Wind gusts of 75 mph were recorded at Fair Isle and Sella Ness (Shetland) on the 7th. A snow depth of 7 cm was measured at Spadeadam (Cumbria) at 0900 GMT on the 22nd.

Weather impacts

Although there were spells of fine early spring weather, there were also incidences of dense fog during the month. This caused some travel disruption on roads, with a number of accidents reported across parts of the South West, particularly Somerset on 13th, and flights were delayed at airports across the country.

England diary of highlights

The month opened with a few days of unsettled weather, but by mid-month high pressure dominated and the country saw a welcome respite to the rain and wind that had defined the preceding winter season. However, dense - and in some places persistent - fog were a problem at times. Some fine and at times warm weather was enjoyed by many, heralding the first spell of more than one or two dry days together since early December. Often sunshine was plentiful, giving rise to some warm days, although nights remained chilly in places. Somewhat more unsettled weather returned later in the month.

The temperature for the month overall was 1.2 °C above the 1981-2010 average. Warm sunny days led to daytime maximum temperatures 2.0 °C above average, and these were particularly high in the east, with Suffolk and Kent having their 2nd highest March maximum temperatures in a series from 1910. In contrast night time minimum temperatures were closer to average. Rainfall was 77% of average, and East Anglia had less than half of average. It was a sunny month everywhere, with 134% of average hours of bright sunshine.
