UK last month

May 2015

At the start of the month, the UK was in a rather unsettled weather type, with some heavy rain in western and northern areas. This set the scene for the month, with a predominantly north-westerly airflow bringing rather wet and cool conditions - especially during the first half. There were only occasional short fine spells mainly in the south. Daytime temperatures were particularly suppressed, and nowhere reached 24 °C during the month.

The provisional UK mean temperature for May 2015 was 9.6 °C, which is 0.8 °C below the 1981-2010 long-term average. For maximum temperatures, this was provisionally the coldest May since 1996. It was coldest relative to average in northern and western areas. Rainfall was above average, with more than double the average in a number of places, and near-normal totals were restricted to southern and eastern areas. The overall UK rainfall total was 157% of average - this being the fourth substantially wetter than average May in the last five years. Sunshine was slightly below normal in many areas, especially across North Wales and Northern Ireland, and the UK received 95% of average sunshine hours.

A maximum temperature of 23.8 °C was recorded at Faversham (Kent) on the 11th. A minimum temperature of -5.6 °C was recorded at Tulloch Bridge (Highland) on the 1st. In the 24 hours ending at 0900 GMT on the 3rd, 101.3 mm of rain fell at Trassey Slievenaman (County Down). A wind gust of 75 mph was recorded at Needles Old Battery (Isle of Wight) on the 6th.
