September: Big Swell Months, Hidden Windows
September continues the pattern of strong swell and tricky local winds. Average wave height remains at 1.4m (4.5-5ft), with the average period easing to 13.0s. Swell direction is still excellent: SSW accounts for 84 percent and SW adds 14.6 percent, making this the month with the broadest SW mix of the green season. There are plenty of waves in the 1.5-2m range - 22.8 percent from SSW and another 4.4 percent from SW - so the power is there. Ideal wind improves slightly to 22 percent, and NW and WNW winds appear a bit more frequently, which can occasionally clean the surface. Rain is the highest yet at 8.68mm/day, while air temperatures cool slightly to 25.5°C and water remains warm at 28.7°C. September rewards surfers who watch the synoptic pattern and strike when a brief offshore window appears between downpours.
