September: The First Real Swell of Autumn
Autumn starts to stir. Average swell height rises to 1.6m (5ft) and period lengthens to 10.5s, a sign that the Atlantic storm track is waking up. The wave rose is extremely favourable: NNW (40.4%) and NW (16.7%) provide the bulk, while WNW (4.6%) and W (2.1%) add secondary open-ocean energy. Swell quality improves, with more observations pushing into the 1.5-2m (5-6.5ft) range. Wind remains tricky - NNE (28.7%) and NE (20.3%) still dominate, but ideal offshore wind increases to 16%, offering a few more clean windows. With water temps at 23.7°C and air around 22.8°C, September is a compelling shoulder month for slightly smaller but increasingly clean surf.
