Conditions at Punta Roca in September
September: The Wind-Swell Trade-Off
September is statistically the ugliest month for surf quality at Punta Roca. Ideal wind collapses to 16%, the second-lowest of the year, while WSW winds flood the region 25.9% of the time and W winds add another 21%. The swell is still present - average 1.0m, period 13.3s - but the SSW/SW mix (90.7% and 9.3% respectively) is frequently destroyed by onshore winds, leaving lumpy, sectiony lines instead of clean point waves. Rainfall peaks at 10.34 mm/day, the air is saturated, and water temperature is 28.3°C. Only a rare strong offshore NE pulse can rescue the month. September is a great time to study the charts and wait for that one clean day, because when it comes, Punta Roca will still deliver.
