September: Great Swell and a Return of Cleaner Wind Windows
September is an often-overlooked gem at Boca Damas. Average swell height holds at 1.4m (4.6ft), average period is 13.1s, and the directional mix remains excellent: SSW 84%, SW 14.6%, with just a touch of S. Wave-height percentages are among the strongest of the year - about 69% are 3-5ft (1-1.5m), 28% are 5-6.5ft (1.5-2m), and 1% are 6.5-8ft (2-2.5m). Best of all, ideal wind conditions rebound to 26%, the highest figure since April, as early northerly pulses mix with the tropical flow. This gives September a rare combination of wet-season size and more frequent offshore N/NNE/NNW opportunities. Rain is still significant at 8.68 mm/day, and water cools slightly to 28.7°C with air at 25.5°C. For experienced surfers, this is a sleeper month when the quality can be excellent.
