The country had its highest wind gust on record during Storm Ophelia, according to Met Eireann’s latest weather summaries.
Roches Point, Co Cork recorded a gust of 155.6km/h on October 16th as well as the highest 10-minute mean speed on record of 114.8 km/h.
Met Éireann said this autumn was characterised by “unsettled weather” mainly due to Storm Ophelia, which claimed three lives.
“Storm Ophelia developed near the Azores late on the second week [OF OCTOBER] before tracking rapidly north-eastwards with hurricane force winds,” the autumn summary states.
The storm made landfall as an “extra-tropical cyclone” and produced violent storm force winds in Munster, strong gale force winds in many areas and destructive gusts widely, Met Éireann said.
Storm Brian affected the country to a lesser extent later on Saturday, October 21st.
Gales and strong gales were reported at “many stations” on October 16th and October 21st. Violent storm force winds were also reported on October 16th at Roches Point and Sherkin Island, Co Cork.
Dublin Airport had its wettest autumn day since 2011 last month. The weather station recorded 52mm of rain on November 22nd, the wettest day over the last three months.

“A ridge of high pressure brought a mainly dry start to the first week with some of the higher temperatures, but the south-westerly Atlantic regime dominated the weather for much of the rest of the month,” the weather summary for November states.
