September: Spring Size with Fading Wind Reliability
September is the springtime tease: the ocean still has winter's muscle, but the winds start to turn against you. Average swell height is 6ft (1.8m), period drops slightly to 9.6s, and ideal wind falls to 28%. The wave rose still shows 19.4% S, 17.3% SSE, 14.5% SE, 13.7% ENE, 13.5% E and 12.5% ESE - plenty of workable swell. Wind is the issue: SSW jumps to 18.8%, NE to 15.4% and NNE to 13.3%, while the W/NW quadrant shrinks to 9.0%. You can still score clean 3-6ft (1-2m) waves, especially before the afternoon sea breeze and on the backside of cold fronts, but you have to pick your sessions carefully. Water temp 21.2°C, air 19.9°C, rainfall 1.46 mm/day.
