10-day surf forecast with Strike Scores for Mullaghmore Head, County Sligo, Ireland
Mullaghmore Head is Ireland's premier big wave slab—a terrifying left that combines Teahupo'o's thick lip with Shipstern's mutant steps to create one of Europe's most challenging waves. When massive North Atlantic swells wrap around the Irish headland, Mullaghmore produces ledging barrels in the 30-50 foot range that defy physics. The wave breaks close to shore, allowing dramatic spectating from the cliffs. Cold water, hostile weather, and serious consequences make this a proving ground for Europe's bravest.
