Conditions at Sennen Cove in February
February: Gritty Midwinter Power
February rarely disappoints for size at Sennen Cove, with average swell heights of 8ft (2.4m) and a long average period of 11.7s. The wave rose remains dominated by WNW through W swell, with W at 19.3%, WSW at 13.9%, and WNW at 7.1% - a strong supply of Atlantic groundswell. The NW and NNW contributions (2.6% and 3.2%) are modest, so the best combo is a long-period W/NW swell meeting an offshore S or SW breeze. Ideal wind only blows 9% of the time, and many days are accompanied by cold, unstable westerly or northwesterly airflow that keeps the beach stormy and cross-onshore. When a transient ridge follows a cold front, light south to west-southwest winds often align with decent sized groundswell to produce clean, hollow peaks. Water temperature drops to 9.4°C, air averages 8.8°C, and precipitation remains high, so bring your thickest wetsuit and patience.
