With long-period groundswell, Mullaghmore starts to show its true colors: thick, heavy, barrelling reef waves that demand respect. Wind conditions are active but workable - S (9%), SSE (10%), SSW (8%), SW (9%), and WSW (9%) provide plenty of offshore and cross-offshore windows. Ideal wind is at 32 percent, so there are consistent opportunities between Atlantic fronts.
