September: Powerhouse Swell Meets Cleaner Skies
September remains a heavyweight month. Average height is 6ft (1.9m), period 14.2s, and the swell direction is heavily locked into the SSW (78 percent), with S (9 percent) and SW (4 percent) playing a lesser role. Over 75 percent of the surf falls in the 5-8ft (1.5-2.5m) range, meaning Desert Point is not just working - it is firing.
The great news is that wind conditions start to improve from the mid-year peak. SE (39 percent) and SSE (34 percent) dominate, but the average wind speed moderates and the ideal wind ratio climbs to 58 percent. Rain stays very low at 1.2 mm/day, air temp is 26°C, and water temperature is 28.2°C. September is a strong contender for the best combination of size and clean surface.
