September: Big Swell Persists, But the Cleanup Crew Is Rare
September hangs on to winter's swell. Average height is still a solid 6ft (1.9m), with an average period of 12.9s, and SSW delivers 73.3 percent of the energy. S swell is also a meaningful 18.6 percent, adding a different line to the SW-facing coast. Around 79 percent of all waves are 5ft (1.5m) or larger, so it remains a proper groundswell month.
Wind conditions soften only slightly. S and SSW still combine for 93.6 percent of the wind, with onshore SW/W components filling the rest. The 10-20kph breeze remains dominant, and ideal offshore flow is 0 percent. Water temperature is at the annual minimum of 15.2°C, air temps are cool at 16.8°C, and precipitation is negligible. September rewards surfers with size and speed, but clean waves are a precious commodity.
