Sea swimming is no longer just for the hardiest among us. In recent years, it has become one of the most popular outdoor activities across Ireland—for health, community, and connection with nature. From icy winter plunges in Dublin to long summer swims off the Wild Atlantic Way, Ireland’s coasts offer world-class swimming spots for all levels.
According to Swim Ireland, participation in open water swimming has more than doubled since 2020, with over 500,000 regular sea swimmers nationwide by 2024. The physical and mental health benefits have been widely recognized, with studies linking cold water swimming to improved mood, circulation, and immune function.
Having personally swum in everything from calm coves in West Cork to choppy surf off Donegal, I can confidently say that Ireland’s sea swimming culture is as strong as its waves—and growing every year.
