A varied April comes to a warm conclusion

April 2019 will be remembered for a combination of both cold and very warm conditions; the latest statistics show that the warmer spells boosted UK mean temperatures to provisionally 1°C above the long-term average when looking at the month as a whole.

After a cold, and in some places wet, start to the month, many will remember the exceptionally warm and sunny weather across the UK over the Easter weekend. A number of records were broken including it being the hottest Easter Monday on record in England, Northern Ireland, Scotland and Wales. Over the Easter weekend a total of 18 weather stations across the UK broke their April temperature records.

The Isle of Wight was the area with the highest average temperature, 10.2°C, with Middlesex, Cornwall and Anglesey closely following. The highest temperature recorded was 25.8°C at Treknow in Cornwall on 19th April. Scotland was also notably warm when compared to the long-term 1981-2010 average with mean temperatures 1.4°C higher for the month.

East Anglia has received just 25% of its average monthly rainfall. The former county of Huntingdonshire was the driest county, with just 9.5mm of rain through the whole of April.
