September: Spring Swell Lingers as the Season Begins to Fade
September is a rewarding, springtime throwback to winter. Average swell height is still 2.7m (8.9ft) with a 12.1s period, so there is no shortage of long-period power. The directional mix remains favorable: SW (17.8%), WSW (9.7%), W (2.7%) and WNW (0.8%) are joined by SSW (11.0%), while S/SSE stay low. Ideal wind drops to 14%, but the frontal passages of early spring still deliver plenty of clean, post-frontal offshore days. SE (16.4%) and SSE (18.2%) winds are common, but they are not as overpowering as in summer, and the NW/NNW sector (20.2%) continues to supply the onshore pre-frontal energy that builds new swell. Air temperatures start to climb to 14.9°C, water temp reaches 15.2°C, and rainfall eases to 1.30mm/day. Catch a late-season west swell and September can produce some of the best sessions of the year.
