September: Late Winter, Still Firing

September continues the winter swell train but with a subtle shift toward spring conditions. The average swell remains at a robust 1.7m (5.6ft), while the period reaches its annual peak of 12.9s - the longest of the year. This means extremely long-period, powerful groundswell. The swell direction is dominated by SW (45.1%) and WSW (21.0%), with SSW (6.7%) and W (6.6%) also in the mix. Wave heights are solid, with a high proportion in the 5-6.5ft (1.5-2m) and 6.5-8ft (2-2.5m) ranges. Wind conditions start to transition, with ideal offshore winds still at 21%, but the direction mix shows more variation: NNW (15.3%), WNW (10.5%), WSW (10.2%), W (9.5%), and NW (8.6%). The increased westerly wind component can create cross-shore or side-shore conditions, so choosing the right part of the tide becomes crucial. Water temp begins to slowly rise to 13.2°C, air temp averages 12.3°C, and precipitation remains high at 2.43 mm/day. September offers some of the biggest and longest period swell of the year - when the wind blows offshore, it's as good as it gets.
