There were four named storms during the 2022/23 storm season. The storm season ran from Thursday 1 September 2022 to Thursday 31 August 2023 (inclusive).
The first named system, Otto, arrived in mid February, producing gale force winds in Donegal with gusts up to 96 km/h and over 27 mm of rain. Two months later, in April, storm force Noa delivered the season's extremes as pressure fell to 977 hPa, Sherkin Island recorded gusts of 122 km/h, heavy rain in Kerry was observed with over 54 mm in a day, and offshore seas rose above 17 m.
Antoni in early August brought gale force winds, gusts just over 100 km/h at Roches Point and almost 49 mm of rainfall at Dublin Airport. Later that month, Betty crossed the country, bringing 74 mm of rain to Valentia and a 12.7 m wave off the Wexford coast.
