September: Autumn Sends Its First Real Swell
September marks the beginning of the comeback. Average swell height lifts to 1.1m (3.5ft), average period extends to 10.8s, and the first meaningful low-pressure systems of autumn start to send groundswell toward Vancouver Island. The swell direction is even more W-heavy than summer-W (47.9%) and WSW (32.7%)-but now more of that energy falls in the 1 to 1.5m range, with occasional 1.5 to 2m pulses. The quality gets a noticeable boost compared with July or August.
Wind becomes more favorable too. Ideal offshore flow jumps to 28%, while the WNW flow (24.9%) and W wind (10.4%) weaken from their summer dominance. Air temperature is still pleasant at 13.5°C, water temperature is 13.6°C, and precipitation is 3.21mm per day. September is the classic wait-for-the-first-real-west-swell-and-an-offshore-east-wind transition month.
