Conditions at Pilar in September
September: Maximum Clean Potential
September edges out August as the best month for offshore flow, with ideal wind at 44 percent - the highest of the year. Offshore W (20 percent), WSW (16 percent) and WNW (7 percent) winds keep Pilar glassy. Swell size is still modest at 2-3ft (0.8m) with a healthy 9.5s period, and the swell mix has more NE (27 percent) and NNE (11 percent), signaling the Pacific is waking up. This is peak typhoon season in the West Pacific, so a well-positioned storm can suddenly transform the clean, small waves into more substantial, long-period groundswell. Air temp is 28°C (82°F), water temperature is 30°C (85°F), and rain averages 6mm/day.
