Aileens is Ireland's most dramatic big wave—a right-hand reef break that detonates beneath the towering Cliffs of Moher on Ireland's west coast. The setting is almost unreal: massive Atlantic swells breaking in front of ancient sea cliffs with birds circling above. When it's on, Aileens produces some of the most powerful waves in the Atlantic, with the added challenge of freezing water and hostile weather.

Aileens is a big-wave spot in Cliffs of Moher, Ireland, that mostly breaks right. It's on our list of the world's 100 best waves.
In 2007 Easkey Britton became the first woman to ride the big wave below the Cliffs of Moher. The cliffs above starred as the 'Cliffs of Insanity' in The Princess Bride, and around 30,000 pairs of seabirds, puffins included, nest on them at peak season.
Aileens picks up swell from the WSW round to the NW, and it's best when it's coming straight out of the W. It starts working at around 7.6m and keeps going up to about 15.2m, with the sweet spot around 9.7 to 12m. Period matters too: aim for 16s or longer, as anything under 14s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An E wind is dead offshore at Aileens, and anything from the NE round to the SE keeps it clean. The morning is typically the best window, roughly 6am to midday. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Aileens isn't especially fussy about tide and generally works through the cycle, so swell and wind matter more here. Big tides can still change how it breaks, so it's worth checking before you paddle out.
The most reliable run of swell at Aileens comes Sep to Mar. There's a second window in Apr too. Rare/inconsistent.
No. As a big-wave spot, it's strictly for experienced surfers. The lineup is usually quiet (crowd 3/10). Things to watch for: shallow water at low tide and sharp, shallow reef (booties help).
The nearest airport on our list is SNN, then it's roughly a one-hour drive. Jet ski or paddle.
The closest breaks we track are Lahinch (6.6 km) and Riley's (9.1 km), handy when Aileens isn't working.
