November: Pre-Summer - Swell Fades, Onshore Winds Return
November sees the surf season winding down. The average swell height eases to 2.0m (6.6ft) and the period shortens to 12.1s. Directionally, SW continues to dominate (48.2%), with SSW at 19.8% and WSW still providing a useful 9.8% - so there's still some decent energy if the winds cooperate. Unfortunately, they often don't: ideal offshore flow drops to just 25%, and the wind rose shows a strong SSW (19.2%) and S (13.6%) presence, making most afternoons bumpy. Water temp warms to 19.8°C and air climbs to 19.2°C, with dry weather (0.91 mm/day) returning. There are still fun waves, but quality depends on catching the morning offshore frames before the seabreeze kicks in.
