Mullaghmore.

Mullaghmore Head juts into the Atlantic at the edge of Donegal Bay, on Ireland’s north-west coast in County Sligo. Classiebawn Castle, completed 1874, sits on the headland above the reef. The wave breaks roughly 100 m off the cliff base, a left-hand slab over a barnacled rock shelf, and one of the heaviest tow waves in Europe. Richie Fitzgerald and Gabe Davies first towed it in the late 1990s. Conor Maguire rode an 18.2 m wave here in October 2020. The bay has nothing else like it.

Peak runs December through March, when North Atlantic depressions send long-period west to north-west swell into Donegal Bay. The reef switches on at 3 to 4 m with period 13 s+. Headline days run past 6 m with the lip thickening to 2 m, tow-only territory. South-east wind is offshore. The take-off jacks fast off the reef and the channel is short. January is the most reliable month, when storm sets line up for days at a time.

Water sits at 8 °C in February and 16 °C in August. A 6/5/4 mm with hood, boots, and gloves through winter; 5/4 mm spring and autumn. The reef is the hazard. The take-off boil sits over a barnacled ledge that nearly dries at low tide. Locals have broken bones in the impact zone. This is not a visitor’s paddle-out. Without a ski and a partner who knows the boil, watch from the cliff. On smaller swells, Mullaghmore Strand has open beach peaks. Bundoran, 15 minutes south, is the call for The Peak and Tullan.
