Autumn was the only season of 2025 to record above average rainfall, following a drier than normal winter, spring, and summer

Northern Ireland experienced its third wettest autumn since records began nearly two centuries ago, according to figures from the Met Office.

Meteorological autumn (September, October and November 2025) saw rainfall 39% above the long-term average, making it one of the wettest seasons since 1836.

Only autumns in 2000 and 2011 were wetter.

Autumn was the only season of 2025 to record above average rainfall, following a drier than normal winter, spring, and summer. They recorded 70%, 72%, and 93% normal rainfall respectively.

Dull, wet and mild

The return of frequent Atlantic weather systems brought repeated spells of rain, with total rainfall for autumn reaching around 449mm - well above the long-term average.

Alongside the rainfall, autumn temperatures in Northern Ireland were around 0.35C above the seasonal average.

While not record-breaking, this continued the trend of milder conditions seen throughout the year.

Sunshine was also in short supply during the autumn months.

With just 80% of its average sunshine it was the fifth dullest autumn on record and the dullest since 1983.

Northern Ireland was affected by several named storms during the season.

Storm Amy, which arrived at the start of October, brought the most significant impacts locally.

Strong winds battered exposed coastal areas, with a weather station at Magilligan in County Londonderry recording gusts of 92mph (148km/h) - a new Northern Ireland record for October.
