Weather in April 2020


Its been a record month for sunshine across the UK which makes a change from the start of the year. April showers didn’t appear until the last two days of the month. With the country on lockdown, it has been so tempting to head for the beach, you just know when the lockdown finishes it will be constantly wet and windy weather. The Central England Temperature came out at 10.42c which was short of the warmest April on record by 0.8c. But it was still a very warm month with it being 2.5c above the long term average, it was the 3rd warmest April since 1667.

Looking ahead to May

Early signs for the first two weeks of the month is that it should be high pressure dominated but the position of the high could mean we get northerly winds and very chilly nights. The rest of May is also looking unsettled with the rain coming back and a fair few northerly plunges which could bring some snow to parts of the UK.
