Cork Airport recorded 251.7mm of rainfall in January 2016, more than 100mm more than any other month of the year.
High rainfall was also measured at Roches Point, Sherkin Island and Fermoy Moorepark as over half of stations nationally reported their wettest winter on record.
Storm Imogen brought the season's highest gusts to Sherkin Island, where wind speeds reached 135km per hour on February 8.
Despite the wet start to the year, spring proved to be mainly dry and cool. Sherkin saw lower rainfall through March and May than in 2014 or 2015, though April was notably wetter than the previous year in all four Cork stations.
Summer was reportedly "mild and dull" with some stations in parts of the West, South and Southeast reporting only three-quarters their normal rainfall for the season.
Temperatures were up on 2015 levels by about one degree on average across Cork, though we didn't see as much sunshine as other parts of the country.
Summer also saw Sherkin Island experience its wettest summer day in 18 years on August 1, when the highest daily rainfall total for summer nationally occurred with 57.9 mm.
September weather was affected by the North Atlantic Jet Stream which made for a mild, wet and windy month. Skies were overcast in Cork, where the lowest monthly total sunshine anywhere in the country during the month of September was recorded at Cork Airport. The station only saw a daily mean of 2.3 hours sunshine per day throughout the month, 52% of their long-term averages.
Later in the season, temperatures were slightly cooler than normal across the board, and while there was heavy rainfall at times, Autumn was "dry overall everywhere".
