September: Hurricane Season Meets Southern Hemi Swell
September is the biggest and most directionally perfect month on paper. Average height is 1.3m (4ft), period 13.2s, and the wave rose is almost entirely in the ideal quadrant: SSW 68.5%, SW 23.0%, plus a touch of WSW at 1.8% - over 93% of all wave energy comes from the optimal directions. This is also the heart of Eastern Pacific tropical cyclone season, so occasional XL juice in the 2-2.5m range is possible if a storm aligns. The catch is wind: ideal winds drop to 62% as WSW (6.9%), SW (6.4%) and W (4.6%) become more common, and rainfall hits its wettest mark at 9.56mm/day. Temperatures stay warm, with air at 27.8°C and water at 29.5°C. When a storm is too close, onshore winds ruin the shape, but when a distant hurricane sends swell from the SSW and the trades hold, you will see some of the best surf of the year.
