Conditions at Impossibles in September

September: The Sweet Spot

September is the pick of the bunch for many locals. The swell is still substantial-6.5ft (2m) at 14.3s-and the direction firms up with SSW at a massive 70.9% and SW at 3.4%, giving eerily consistent groundswell. The wind regime transitions to lighter trade winds: ESE (39.1%) and SE (32.5%) are now more evenly balanced, but the strongest ESE gusts are down to 9.7% at 20-30kph. Ideal wind percentage soars to 77%, and the lack of W/NW winds leaves the surface glassy for long stretches. Rain returns slightly to 0.98mm/day, water temperature bottom out at 26.8°C, and air temperatures average 25.8°C. This is the classic dry-season sweet spot-big, clean, and everywhere.
