September: Fall Cleanup Begins
September is a transitional month that trends better. The ideal wind percentage climbs back to 52 percent, and the average swell height sits at 2-3ft (0.7-0.8m) with a 6.1s period. ESE swell is still the leader at 48.1 percent, with E at 34.3 percent and SE at 11.3 percent. Perhaps more importantly, the wind field begins to loosen: E drops to 31.8 percent, ESE to 26.7 percent, and SE increases to 10.6 percent, while S/SSW/SW components grow. Those southern breezes are offshore for a north-facing beach and bring more groomed, glassy conditions. Water temp peaks at 29.2°C, air temp averages 27.8°C, and rainfall jumps to 6.02mm/day as the wet season gathers. September can also see the first tropical swells of the fall, which occasionally add a couple feet of extra push to the usual trade peaks. It's a promising month for small-wave surfers.
