S/SW/WSW swells are still present - SW 22.4%, WSW 22.3% and SSW 2.6% - but N (7.9%) and NNW (14.1%) energy is returning, giving the region a mixed wave spectrum. Average height is around 3ft (0.9m) with a 7.1s period. Wind conditions improve from summer, with ideal wind at 25%, although SSW (15.0%) and S (12.9%) still dominate many days. Rainfall remains heavy at 12.97 mm/day, while air temp averages 25.4°C and water temp is a warm 29.7°C. Each passing cold surge or tropical storm brings more chances for offshore flow, and by late September the first clean groundswell of the autumn is possible.
