Conditions at San Pedrito in September
September: Hurricane X-Factor
September is statistically the wettest and stormiest month on the Mexican Pacific coast, but for surfers it is also the X-factor. The average height remains 4-5ft (1.2-1.5m) and the 13.1s period is still long-period groundswell. Swell direction is dominated by SSW (39 percent), SW (30 percent) and WSW (16 percent), with a big boost from S (6 percent) and SSE (1 percent). Eastern Pacific tropical cyclones can inject oversized, powerful swell into that directional window, occasionally pushing the beach well overhead. The trade-off is wind and rain: ideal wind sits at only 47 percent, precipitation reaches 3.33 mm/day, and water temperature peaks at 29.3°C. Air temperatures average 27.9°C. Track the storms and score the dawn cleanups-September can be the most memorable month of the year.
