Mullaghmore Head Surf Season
County Sligo, Ireland · part of the Mullaghmore Head spot guide
Prime is October to March, peaking in December and January, when the Iceland Low and North Atlantic depression track — occasionally an ex-tropical transition — send big long-period swell across the open Atlantic. Summer is dead. Even in the prime months there are only a handful of genuinely big days each winter, and each one needs a large swell with an offshore lull behind the front.
Where the swell comes from
Deep Iceland Low and North Atlantic depressions with a long west-to-northwest fetch at Donegal Bay, occasionally seeded by ex-tropical systems.
Historic swells at Mullaghmore Head
Hurricane Epsilon swell
Widely cited as producing the largest wave ever surfed in Ireland — around a 60-foot face — as Epsilon stacked on a mid-Atlantic depression and waves broke roughly a mile out, drawing big-wave award nominations.
