Conditions at The Bluff in September
September: Early Spring Swell Meets Squally Wind
September still sees winter-sized surf, averaging 5.2ft (1.6m) with a 13.8s period, but ideal wind drops to 16%. The swell rose is extraordinarily one-sided: SW accounts for 65.6% and SSW for 25.9%, leaving little true W/NW energy. Height-wise, the 3-5ft (1-1.5m) and 5-6ft (1.5-2m) bands are nearly equal, with plenty of 6-8ft (1.8-2.4m) and bigger southwest pulses. Winds turn squally from the S (28.1%) and SSW (21.6%), so surface conditions are often blown out. Patience is required; the best windows come with SSE/SE flow after fronts push through. Water temp is 21.7°C, air temp 21.0°C.
