UK overview

The cold dry weather of late March continued into the first few days of April. Temperatures did return to near the seasonal average as the month progressed, as the persistent easterly winds finally gave way to winds from a westerly or southerly quarter around 11th. Temperatures rose as high as 23 °C in some eastern areas on 25th, but it then became rather chillier once again, especially at night with some late-season frosts occurring quite widely on 29th and 30th.

Temperatures for April were below average everywhere. The UK mean temperature was 6.3 °C, which is 1.1 °C below the 1981-2010 average, very similar to 2012 but otherwise the coldest April for the UK since 1989. The month was drier than average across most of England and Wales, with a band from Cheshire to Humberside receiving less than 20% of average. In contrast northern and western Scotland received higher than average rainfall for the month. The UK overall had 87% of average rainfall. There was 113% of the long-term average sunshine for the UK overall, with most of Scotland and eastern areas of England above average.

A maximum temperature of 23.1 °C was recorded at Faversham (Kent) on the 25th. A minimum temperature of -11.2 °C was recorded at Braemar (Aberdeenshire) on the 2nd. In the 24 hours ending at 0900 GMT on the 18th, 84.8 mm of rain fell at High Snab Farm (Cumbria). A wind gust of 84 mph was recorded at Aberdaron (Gwynedd) on the 18th. At 0900 GMT on the 1st, a snow-depth of 22 cm was measured at Ballypatrick (Antrim).

Weather impacts

The cold weather of March persisted into early April with some ice and wintry snow showers. As mid-month approached some warnings of low-level impacts from rain and snow melt were issued for parts of central Scotland.

In the middle of the month some disruption was caused by high winds, particularly around the 17th and 18th for north-west Wales, northern England and southern Scotland.
