September: The Rainy-Season Grind
September is the wettest month at 9.73mm/day and the wind statistics are the least favorable of the year, with ideal conditions only 31% of the time. The N/NNE offshore flow is reduced to a shadow, while onshore S/SW/WSW winds become dominant. Swell remains strong though - 1.5m (5ft) at 13.0s - and the SSW/SW split of 75.0% and 22.4% is excellent for the beach. That means the rare N or NNE day in September will deliver extremely clean, powerful surf. Air temps cool slightly to 27.0°C and water sits at 28.8°C. Surfers need patience and a flexible schedule, but the South Pacific is still sending energy.
