Conditions at Coke's in September
September: Southern Energy Maintained, Wind Strength Waning
September continues the southwest monsoon but with gradually easing wind speed. The monsoon trough is still active, and Southern Ocean swell keeps rolling in at 1.1m average height with a healthy 8.4s period. Directionally, SSE/S/SSW remains well represented - SSE at 15.3%, S at 18.9% and SSW at 14.3% - so Coke's continues to see the right swell window. The biggest issue is that W and WNW winds are still frequent, collectively exceeding 59% of observations.
The ideal wind score stays at 39%, and rain potential peaks at around 6.02mm per day. Air and water temperatures remain steady at 27.5°C and 29.1°C. The surf is often 3-4ft (0.9-1.2m) and consistent, but clean conditions are reserved for windows of N/NNW flow or lighter morning breezes. September is a reliable backup month - slightly less powerful than August, but still capable of excellent reef waves when the synoptic wind relaxes.
