September: The Cleanest Window of the Year
September is the sweet spot of the dry season. Average swell height is a solid 6-7ft (2.0m) and period remains a powerful 14.3s. The swell direction is heavily favored to the SSW at 70.9%, with S adding 11.3% and SW 3.4%, so the beach is constantly in the firing line. The wind is the real star: ESE 36.6%, SE 37.5% and SSE 12.9%, but without the extreme wind speeds of July and August. That lifts ideal wind to 75%, the highest of the year. Rain is minimal at 1.14mm/day and water temp is 26.8°C. Expect clean, lined-up sets stacking on the sandbars, with plenty of long rides and rippable walls from first light through the afternoon.
