Climate Statement for April 2020

April 2020 was very dry, mild and sunny

The very dry weather, which started in the final third of March, with high pressure dominating, continued through most of April. This led to absolute drought, partial drought and dry spell conditions being reported at many stations between the 18th March and the 29th April, most especially in the Northwest and East. Atlantic weather fronts broke through from the south and southwest at times, such as on Sunday the 5th, between Friday the 10th and Easter Sunday the 12th and between Friday the 17th and Sunday the 19th, but pressure stayed relatively high and rainfall amounts relatively low, apart from a few heavy falls in the South and Southwest. It was cool and cloudy at times, especially at the start of the month, in a northerly airflow, when high pressure was located to the west of Ireland. There were also numerous warm sunny days, especially during the mid-week periods, when high pres-sure built directly over or to the northeast of Ireland. It was warmest in the western half of the country during these periods, as the winds were mostly from the east off a cool Irish sea. The weather finally broke on the 29th as a complex area of low pressure brought active weather fronts across the country from the south and southwest, followed by showers on the 30th.
