September: Late-Season Size and the Broadest Swell Direction
September is the last full month of the southern-inspired swell season, and it goes out with a punch. Height holds at 4-5ft (1.4m), period is 13.0s, and the directional spectrum broadens significantly-SSW drops to 73.1% but SW surges to 16.2% and WSW to 1.8%, while S still provides 8.7%. This makes for a more west-tilted swell mix that can wrap into the corner differently.
The 5-8ft (1.5-2.5m) range contains a healthy 30% of all waves, one of the highest of the year. On the flip side, precipitation peaks at 8.14 mm/day and ideal winds drop to 53%. Water temperature is 29.9°C and air temps cool to a 26.4°C average. It is still prime time for bigger morning sessions, just expect showers and the occasional stormy afternoon.
