November: Consistency Returns

Average swell height is 1.3m (4.3ft) with a 7.3s period, and while S (8.4%), E (9.7%), ESE (8.6%), SSE (7.9%) and SE (7.7%) share the swell pie, the favorable window still totals 33%. The wind is the big win: WNW (13.0%), NW (11.7%) and NNW (11.2%) dominate, and the 'ideal wind' percentage is 26%. This means frequent offshore grooming of the south/east windswell, producing clean, punchy, rideable waves. Water temps have dropped to 13.2°C (56°F) and air temps to 9.4°C (49°F).
