The following represents an assessment of the weather experienced across the UK during Spring 2017 (March to May) and how it compares with the 1981 to 2010 average.
This was a warm and rather dry spring. It was generally warmer than average during March and early April, but the second half of April was cooler, with some cold nights and numerous late frosts. May was predominantly warm, especially early and late in the month. April was much drier than average for most areas, but parts of north-west Scotland were wet. May was somewhat wetter than average in some south-eastern parts, but quite dry in much of the north and west. Sunshine was above average for Spring in most areas, though not in the far south-west.
March 2017 was warmer than average in all areas, by well over 2 °C over parts of East Anglia and south-east England, and the UK monthly mean temperature was +1.8 °C above the long-term average. This was the joint fifth warmest March in a series since 1910. April continued warmer than average for the first half, but cooler weather later in the month meant that the overall mean temperature for the month was just +0.6 °C above average. May was another warm month, with only short cooler spells, with an overall mean temperature +1.8 °C above average, the second warmest May in the series . This spring overall was the UK’s equal-warmest in the series (with 2011).
March was somewhat wetter than average over Wales, much of northern England and south-east Scotland, but slightly drier for north-west Scotland and also drier than average in south-east England. Overall the UK had 103% of average rainfall. April was drier than average in most areas, with less than a third of the average rainfall in many places, and some stations near both London and Edinburgh received only around 5 mm in the whole month. The UK overall had 46% of average rainfall in April. In May the overall figure was 82%, but southern and eastern parts of England did have a rather wet month.
Most areas were sunnier than average during each of the three spring months. The exceptions were south-west England and south Wales in March, Northern Ireland and western and northern Scotland in April, and much of southern England in May. Sunshine totals for the UK overall were 118% of average in March, 107% of average in April, and 112% in May.
