It was the wettest August in parts of the country in more than 170 years, according to figures released by Met Éireann.
The heavy rain last month lead to flooding in many areas and misery for those hoping to enjoy the summer sunshine.
The Met service said low pressure close to or over Ireland brought a succession of Atlantic frontal systems across the country, giving some significant falls of rain.
It was the wettest August on record at Dublin’s Phoenix Park weather station, where rainfall records began in 1837. Birr had its wettest August since 1917, while Dublin Airport had both its highest monthly total (190mm) and highest one-day fall (76.2mm on the 9th) for August since the station opened in 1941.
In Shannon, Co Clare, a 60-minute fall of 38.4mm of rain on August 6th was the highest for any month in the station’s 63-year history.
The number of wetdays (days with 1mm or more rainfall) recorded during the month was also well above normal; there were between 14 and 21 wetdays at most stations this month compared with the August average number of between 10 and 14.
Mean air temperatures for the month were between half a degree and one degree higher than normal generally, Met Éireann said.
Sunshine totals were exceptionally low, with between 20 and 40 per cent less sunshine than normal at all stations.
