UK climate video
At the start of April, the UK's weather was unsettled and dominated by low pressure, with frequent showers and some longer spells of rain. This unsettled regime continued into the second week, with low pressure to the south-west in the Atlantic drawing in an easterly airstream. The second half of April was mostly cold, bright and showery with frequent northerly winds, although there was a brief warm sunny spell in central and northern areas between the 19th and 22nd. Sleet and snow fell unusually widely for late-April between the 26th and 29th, with some accumulations even at lower levels in the north-east accompanied by sharp frosts.
The UK mean temperature was 6.5 °C, which is 0.9 °C below the 1981-2010 long-term average, and all regions were colder than average. Rainfall was 107% of average, and it was generally wetter than average in eastern areas, particularly near the east coast of Scotland, but it was drier than average in south-west England. Sunshine was generally near or slightly above average, and the UK had 109% of average sunshine overall.
The UK monthly extremes were as follows: A maximum temperature of 20.3 °C was recorded at Porthmadog (Gwynedd) on the 21st. A minimum temperature of -5.6 °C was recorded at Kinbrace (Sutherland) on the 28th. In the 24 hours ending at 0900 GMT on the 2nd, 86.6 mm of rain fell at Seathwaite (Cumbria). A wind gust of 57 knots (66 mph) was recorded at High Bradfield (South Yorkshire) on the 6th. A snow depth of 9 cm was measured at Leadhills (Lanarkshire) at 0900 GMT on the 29th.

Thunderstorms affected north Essex, south and east Suffolk on the 12th, and lightning strikes and torrential rain affected the activities at Ipswich Hospital. A lightning strike caused the failure of the hospital's pager system and flooding affected some computers. Thunderstorms also affected parts of Kent on the 13th, and a Morrison's supermarket in Canterbury was evacuated after the building was reported to have been twice struck by lightning during the afternoon.
On the 15th, localised surface water flooding from heavy downpours was reported to have caused traffic disruption and long travel delays in parts of Greater London during the evening rush hour.
During the last week of April, a cold, northerly airflow introduced arctic air across much of the UK bringing wintry showers and overnight frosts. From 25th to 27th, some high level routes had some limited snow, with the temporary closure of a couple of the highest and most prone routes.
An Atlantic low pressure system introduced some more persistent snow across parts of Scotland on 28th and 29th. Very difficult driving conditions were reported as the band of rain, sleet and snow moved across northern parts of the UK, with the combination of snow and wind leading to blizzard conditions on some main routes. The island of Mull was badly affected by lying snow, with reports of cars being trapped in snow and ferries unable to run due to the closure of the access road. Some road traffic collisions were reported on higher routes in Cumbria, and snow was also reported to have caused some limited travel disruption in Lancashire, Greater Manchester, Derbyshire, West and North Yorkshire, and north Wales.
