September: Spring Energy and Trade-Wind Tug
September produces the biggest average swell of the year at 5ft (1.5m), but it is also the month when the trade winds start to muscle back in. The swell window is still packed with E (20.8%), ESE (19.1%) and ENE (18.4%), plus solid SE (15.4%), SSE (12.1%) and S (9.3%) contributions. The wave heights are substantial - many 3-5ft (1-1.5m) waves, a healthy amount of 5-6ft (1.5-2m), and occasional 6-8ft (2-2.5m) sets from the ESE/E side. The problem is wind. NNE flow jumps to 24.9% and ideal offshore conditions drop to 36%, so the bigger waves are often accompanied by textured, cross-shore surf. Water temperature is still cool at 18.3°C, air averages 17.0°C, and rainfall increases to 4.67 mm/day. Catch a cold-front passage with W/NW winds and you will score late-season gems.
