September: Tradies Ease and Better Windows Return
September is the first month of spring that starts to feel like a change is coming. The average swell height remains solid at 1.3m (4-5ft), although the period drops to 6.9s, so the surf is a bit more short-period and crumbly. SSE/SE swell still fills 99.1 percent of the rose, with a good share of chest-to-head-high sets in the 1-1.5m range. The SE wind eases enough to lift the ideal-wind percentage to 32 percent, and strong gale-force trade winds are less frequent than in July and August. That makes September a touch more user-friendly, especially on a lower tide reef setup.
Dry conditions persist with 0.90mm/day of rain, air temps average 26.1C and water temp holds at 25.2C. It is still an off-angle trade-swell month, but the ocean is becoming more cooperative.
