Conditions at Pine Trees in September
September: Early-Season Hurricanes and First North Pacific Hints
September is still a slow month, but the balance starts to shift. Average wave height remains 2.5ft (0.8m), period is 13.5s, and the dominant directions are still S at 49.5% and SSE at 16.0%. However, SSW at 19.9% and SW at 7.5% have a stronger presence, which is promising for the WSW-facing break. This is also a peak part of the tropical cyclone calendar in the Pacific, and a well-placed storm to the south/southeast can produce a fun, clean SSW/SW groundswell for a day or two. Offshore wind days remain limited at 12%, with WSW/SW winds continuing to rule the afternoons. Water temp reaches its annual maximum of 26.8°C, and average rainfall stays low at 1.43mm/day. Early-season swells are possible, but reliability is still low.
