September: Spring Transition and Shifting Winds
September is a transition month with plenty of raw energy. The average swell is still 10ft (3.0m) with an 11.8s period, but consistency starts to waver. Ideal wind drops to 26%, and the wind rose shows a more even split between offshore W/WSW flow and the rebuilding onshore E/ESE flow. Direct E/ESE/SE swell improves to 6.6%, giving a few more waves from the exposed direction. As air temperatures rise to 16.1°C and water warms to 17.0°C, the ocean becomes slightly more inviting but slightly less reliable. Look for S/SSW/SW groundswell hitched to cold fronts; it is still winter enough to produce serious surf, but you need to ignore the occasional spring onshore flow.
