Conditions at Jake's Point in September
September: Spring Swell Remains Strong, Wind Gets Fickle
September is a transition month, but the ocean hasn't gotten the memo yet. Average size stays at 6ft (1.9m) and the average period is a solid 12.0s. Swell direction remains westerly enough: SW 44%, SSW 28%, WSW 9%, with S and W small. There is still plenty of Southern Ocean juice, and the spot will see some of the largest, most powerful swells of the year.
The issue is wind. Ideal offshore flow drops to 34%, with SSE (16.6%) and S (16.5%) regaining dominance, while SE (11.8%), E (4.8%) and ESE (8.2%) offer fewer clean windows. The autumn/winter consistency is over; you need to pick your days. Water temp is at its annual low of 19.6°C and air averages 17.5°C. Expect punchy, powerful surf on the best days and lumpy, cross-offshore slop on the rest.
