Conditions at Curl Curl in August
August: Still Winter, Just Less Predictable
August keeps the winter surf alive but with a slight drop in consistency. Average wave height is around 5ft (1.6m), period 9.2s, and ideal wind 39%. The data show a growing S component: S (17.1%) edges out SSE (16.4%), with SE (10.2%), SSW (6.2%) and SW (4.0%) all taking a larger share of the spectrum. Wind-wise, winter westerlies are still frequent, with W (12.0%), NNW (11.6%), WNW (9.8%), NW (9.9%) and WSW (10.9%), but the strengthening spring sun starts to generate afternoon sea breezes. Water temperature reaches the annual minimum of 18.2C, air averages 14.4C, and rainfall is low at 1.75mm/day. There is plenty of power in the water, especially when S/SE groundswell lines hit the beach, but days with pure E/ESE swell become rarer. Expect good-to-excellent surf when the wind stays offshore; on days with S/SW winds, the banks turn lumpy and windblown.
