Open-water swimming weather in Cork

If you're planning anything outdoors in Cork, the city's south coast Irish position makes it one of the wetter places in the UK and Ireland — well above 200 rainy days a year, with December the wettest month and summer fog a regular feature. The trade-off is mild: winters are gentle thanks to the Gulf Stream, snow is rare, and the growing season runs long.

If you're swimming open-water around Cork (Sandycove, Fountainstown, Garrettstown), the south coast sea temperatures benefit from the mild climate and the season runs longer than further north — but Atlantic swell, currents and summer fog all need careful planning, and conditions can change fast.
