September: Autumn's First Signs Of Life
September is the pivot from summer doldrums toward winter power. Average swell heights jump to 6.2ft (1.9m), and although the average period is still short at 9.9 seconds, the energy is clearly building. WSW and SW swells continue to rule, and the mix of S and SSW energy adds some variety. The wind starts to shift away from pure westerly onshore flow, with ESE, SE and SSE winds becoming prominent; ideal offshore flow sits at 35%. This is also the peak of hurricane season, meaning a single storm can flip the spot from flat to epic. Water temp is a pleasant 13.0°C, making September an appealing transition month.
