Dublin Airport posted its dullest summer on record this year, according to the national forecaster, after its sunniest spring earlier this year.
Met Éireann launched her 2020 summer climate statement, which he described the past three months as “wet and boring with a stormy ending.”
From a relatively dry start, June saw two intense storm outbreaks, between the 13th and 16th and the 25th and 26th, when warm, humid air rose from the southeast over the country.
Strong air currents, known as the jet stream, were most active near Ireland in the last third of the month with the Atlantic low pressure systems bringing rain or squalls on most days.
The jet stream weakened for a while after the first week of August, which brought some nice dry days, but slow-moving fronts and stormy low-pressure continental systems kept it mostly cloudy with heavy rain at times.
The last third of August brought two named storms, Storm Ellen and Storm Francis, over the country with widespread gales and heavy rains causing some flooding.
Sunlight levels were below their long-term monthly average (LTA) for the season at all locations.
Casement Airfield, Co Dublin, had its most boring summer since 1987 when it logged 361.2 hours of sunshine, 78 percent of its LTA. Meanwhile, Cork Airport had the highest seasonal total sunshine at 89 percent of its LTA, accounting for 451.2 hours.
Seasonal sunshine totals were lowest at Gurteen, Co Tipperary, at 275.5 hours.
The highest number of hours of daily sunshine on record this season was on June 1 with 15.6 hours of sunshine at Johnstown Castle, Co Wexford.
The number of boring days ranged from 15 days at Johnstown Castle, Co Wexford to 30 days at the Valentia Observatory, Co Kerry.
Dublin airport logged 22 boring days. After its sunniest spring on record this year, Dublin Airport had its dullest summer since records began 78 years ago, with just 331.4 hours of sunshine.
Rain totals across the country were above their LTA for the season.
Oak Park, in Co Carlow, had the lowest seasonal precipitation at 217.1 mm, while Valentia Observatory, Co Kerry, had the highest seasonal precipitation at 561.1 mm, making it the wettest summer since 2009.
The wettest day of the season was also recorded at the Valentia Observatory, Co Kerry with 54.5mm on Wednesday July 29th.
Up to 11 stations had their coldest summer in the past five years, with most average air temperatures across the country below their LTA for the season.
The highest temperature of the season was reported on June 1 in Newport, Co May, with a temperature of 27.1 degrees.
