October: The Peak of Optimal Direction
October is a statistical standout because the swell direction aligns with this beach more than any other month. An incredible 55.1% of all swell arrives from the preferred SE/SSE/S/SSW quadrant, with S leading at 20.8% and SSE at 15.6%. Average height drops slightly to 5ft (1.6m) and period to 10.3s, but the quality of direction means the island's banks see a far higher percentage of clean, ridable surf. The S column still produces 7.1% of waves in the 1.5-2m (5-6.6ft) range and 3.3% in the 2-2.5m (6.6-8.2ft) range. Winds are favorable 49% of the time, with a strong NW/NNW offshore flow - NNW (15.0%), NW (13.5%) and WNW (13.0%) - keeping the surface glassy between fronts. Water temps begin to rise to 14.8°C, air averages 13.0°C, and precipitation is a lighter 2.40mm/day. If you want dedicated S/SSE groundswell with offshore wind, October is hard to beat.
