September: Spring Mix and Window Watching
September is a true transition month. The average swell holds at 1.6m (5ft), the period drops to 9.0s, and ideal winds sit at a still-respectable 34 percent. Swell direction remains southern-heavy with SSE (18 percent) and S (16 percent), but NE (9 percent) and ENE (9 percent) energy is back in the mix, bringing a shorter-period component. Winds become more variable: NNW leads with 12 percent, W follows with 9 percent, S with 8 percent, WSW with 8 percent and NW with 7 percent. The result is a mix of winter groundswell and fresh spring breezes, with some world-class days and some bumpy sea-breeze afternoons.
