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 has been 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 provisionally 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 +1.7 °C above average, the second warmest May in the series . This Spring overall was the UK’s second warmest in the series, with only 2011 having been slightly warmer.

Overall the UK had 104% 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 48% of average rainfall in April. In May the overall figure was 83%, 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 121% of average in March, 109% of average in April, and 115% in May.
