April the rainiest since 1940, but weekend is likely to be a scorcher

Parts of Ireland experienced the wettest April since World War Two, while the rest of the country endured above average rainfall and below average sunshine.

In the monthly weather summary from Met Eireann that was published yesterday, the Valencia weather station in Co Kerry recorded the wettest April since 1940.

The 197.9mm of rain that fell there was more than twice its normal long-term average for the month.

The same station also rec- orded the greatest rainfall in one day when 46.2mm was recorded on April 16 - the wettest April day there since 2003.

Cork Airport also endured a soggy month, recording rainfall for 24 out of 31 days, while also recording rainfall under 0.2mms for 28 "rain" days, compared with Malin Head, Co Donegal, which had 11 wet days with rain exceeding 1mm and 14 rain days.

Both Cork Airport and Valencia also recorded seven very wet days.

Unsettled

The only consolation to a wet and dreary month - which was largely unsettled except for a few fine days during the third week - was that the monthly mean temperatures were slightly above average.

Dublin's Phoenix Park and Malin Head were treated to a blast of warm air and sunshine on April 18 when temperatures soared to 20C.

At the other end of the scale, the mercury dipped to -5.3C in Mullingar, Co Westmeath, on April 5 - its lowest daily temperature since the same date in 2013.

The amount of sunshine nationally was also below the monthly average, with Cork Airport receiving only 65pc of its average monthly sunshine at 104.9 hours - its dullest month since 1987.

By contrast, Casement Aerodrome in Dublin recorded 165.4 hours of sunshine for the month, with April 20 having 14.9 hours, the most recorded on that day since 1964.

While the start of May has been marked by unseasonably cold and blustery weather, that is set to change from tomorrow, according to Met Eireann meteorologist John Eagleton.

"The weather is pretty optimistic for the bank holiday," he told the Herald.

While today will start off "a bit misty and drizzly", conditions will start improving and get progressively better over the weekend, with more dry and sunny weather kicking in from tomorrow.

Monday will be the best day, with temperatures soaring to 22C, though it will be cooler along the eastern coast.
