The averaging period used for the following assessment was 1961-1990.

UK overview

A very mild and sunny month across the whole of the UK. It was also a fairly dry month across Northern Ireland, England and Wales, with only central parts of Scotland and the Northern Isles experiencing above average rainfall.

With gusts of over 60 knots on the 9th over Norfolk, a marked 'Fen Blow' was experienced as the strong winds lifted the topsoil. Boltshope Park in Durham reported 10 cm of lying snow on the morning of the 10th.

England and Wales diary of highlights

Mostly mild and mainly dry. Changeable at first, then a notable gale on the 9th, with a little snow in the north. A wet third week, then dry sunny and very mild by day, but with some frost and fog overnight.

1st to 8th A changeable, mainly dry period as weak fronts crossed the region between low pressure to the north and high pressure to the south. There were sunny periods but it was rather cold at first with some overnight frost and fog patches and some occasional wintry showers in the north-east. From the 5th onwards it was mild or very mild, however the 6th was windy with some rain in the north.

9th to 13th
Generally changeable with occasional rain and mostly mild. A small intense low moved eastwards across northern districts during the 9th bringing gales to many areas and some snow to high ground in northern England. With gusts over 60 knots in Norfolk a marked 'Fen Blow' was experienced as the strong winds lifted the topsoil. A gust of 67 knots was recorded at Mumbles Head in south Wales. The 10th was also windy with more gales in western and northern areas, while Boltshope Park (Durham) boasted 10 cm of snow that morning. As low pressure transferred to Biscay during the 12/13th a quieter interlude developed. Northern areas were sunny but with overnight frost, Shap (Cumbria) falling to -6.5 °C early on the 13th. Rain affected extreme southern areas from time to time.

14th to 20th
Unsettled with periods of rain heavy at times. An anticyclone over Scandinavia fed chilly easterly winds at first, but falling pressure in the south-west approaches brought rain on the 14th and 15th, especially to southern areas. Thundery showers affected the Norfolk / Suffolk coast later on the 15th. Low pressure centred in mid North Atlantic brought mild southerly winds on the 16th and 17th but rain heavy at times spread in later, with thunder reported along the Channel coast. The 18th was wet as a low moved from the Severn estuary to the Wash, while rain with hill and coastal fog were the uninvited guests to southern parts on the 19th and 20th.

21st to 31st Mainly dry, sunny anticyclonic weather prevailed as pressure rose over the region and drifted east. It was mostly very mild by day but with some overnight fog and frost later. On the 28th early morning fog caused multiple accidents on the M40. The 29th and 30th saw temperatures reach 18 °C in the London area, making it the capital's warmest March Good Friday, although scattered showers affected places in the Midlands, East Anglia and south-east England later. As the high pressure lost ground Atlantic fronts brought patchy rain and drizzle to many areas on the 31st.

Scotland diary of highlights

Mostly mild and unsettled, but with two fine spells.

The weather in March was varied, with no particular spell of weather lasting for a long time. Mild weather predominated, with relatively little frost and snow.

The month began with a cold and clear northerly outbreak, but winds soon backed into the west, allowing mild and cloudy weather to advance across the country.

Strong westerly winds blew between the 4th and 6th, with gusts reaching 64 knots at Muckle Holm on Shetland on the 4th. Mild and humid air brought torrential rain to the West Highlands on the 5th, with several gauges recording over 80 mm.

Westerly winds continued for the next few days, but it became colder, with snow extending to low levels between the 9th and 10th. The precipitation took the form of showers on the 9th, with more general snow for a time early on the 10th. Gusts reached 69 knots at Barra on the 11th.

An anticyclone that developed over Scotland gave the first fine spell between the 12th and 14th. The clear skies and light winds allowed the temperature at Corgarff to drop to -7.3 °C on the 14th.

Southerly winds covered Scotland between the 15th and 19th as the high moved away to the east. After a period of cloud with some rain, milder and brighter weather arrived.

From the 19th to the 25th, a contrast in weather across Scotland was brought about by a slow moving front. The north-east was bright and rather cold, while the south-west was cloudy with outbreaks of rain.

An anticyclone, which became slow moving over Germany, gave the second fine spell over most of the country from the 26th to 29th. In the north-west it was rather cloudy, with south-westerly winds gusting to 61 knots at Stornoway on the 26th. For the bulk of Scotland there was much sunshine, with frost at night and pleasantly warm days. On the 28th the temperature at Fyvie Castle rose to 18.5 °C.

As the high retreated, the last couple of days saw the return of cloudy weather with a little rain.
