Conditions at Lakey Peak in September
September: Late-Season Power Holds
September is still excellent, although the wind field begins to shift. Average swell remains at 5-6ft (1.7m) with a 14.3s period, and the SSW sector is dominant at 77%, with SW adding 17%. The 5-6.5ft (1.5-2m) range is the biggest single height class, so the reefs stay well-charged. The trade wind regime begins to weaken, however: SSE becomes the leading wind direction at 29%, and S flow jumps to 24%. The offshore component (E through SSE) still delivers clean surf 82% of the time, but the increasing southerly component means some sessions get cross-offshore rather than pure offshore. Rain remains negligible at 0.52mm/day and water temps are still cool, a good sign for late-season swells. Days are still firing, but the monsoon change is in the air.
