September: The Winter Fade Begins
September still has plenty of pulse, but the season is starting to wind down. The average swell height remains at 1.5m (4.9ft), but the period drops to 12.2s. The SSW contribution grows to 31.2 percent while SW provides 65.1 percent. The height distribution still shows a healthy 1.5-2m (5-6.5ft) class at nearly 30 percent and a 2-2.5m (6.5-8ft) class at 10.3 percent, but the overall period loss means the wave quality on the sandbar becomes slightly less defined than in July and August.
Winds are mixed: ideal surf conditions fall to 42 percent as the transition toward spring begins. S and SSW winds are still plentiful at around 49 percent combined, but the N-NW onshore sector increases a little to 14 percent, and the wind is less consistently light. Water temperature sits at 12.9°C, air temperature averages 15.4°C, and precipitation remains negligible. September is a solid choice for surfers who want winter-sized swell with slightly less punishing conditions, although the premium barrels become more selective.
