September: The Biggest, But Windy
September delivers the highest average swell height of the year at 5.9ft (1.8m), but the wind roulette becomes less favourable. Ideal wind frequency drops to 28%, and NE (20.3%) is the dominant wind direction, creating blown-out and bumpy conditions. Swell distribution is still powerful, with ENE (18.9%), E (15.7%), ESE (13.9%), SE (13.6%), SSE (12.0%), and S (10.4%) all contributing solid amounts of 1.5-2.5m (5-8ft) energy. The period is a respectable 9.1s, so when a strong high-pressure system sets in and winds clock to the west, the surf can be truly spectacular - big, powerful, and lined up. But those windows are rare and precious. Water temp is 17.1°C and air temps average 15.8°C. Surf big waves if you can pick the days; otherwise expect washed-out conditions.
