July: Small Summer Grovelers and Onshore Afternoons
The summer lull tightens in July. Swell from SW and WSW together accounts for 77% of the wave rose, with SSW contributing 14%. Average height is 0.8m and the average period is 12.7s, which is classic southern hemi groundswell energy, but only 6-7% of readings reach above 1m (3.3ft). Ideal wind plummets to 12%, and the daily W wind regime at 28.9% plus WSW at 24.7% makes afternoon surface chop almost a given. Air averages 23.1°C and water is 17.0°C. It is time for small-wave boards and ultra-early sessions before the sea breeze kicks in.
