October: Spring Squeeze and Tricky Winds
October keeps the average wave height at a wintery 5ft (1.6m) and period at a solid 13.0s, but surf quality drops because ideal wind collapses to just 11%. The S (32.7%) and SSW (29.0%) wind directions often blow at 20-40kph, putting a cap on clean conditions. Swell remains locked in the SW (57.0%) and SSW (37.4%) quadrants, with plenty of 5-8ft (1.5-2.4m) groundswell still showing. The near-total absence of any N/NW swell makes October an inconsistent month to score Gnaraloo at its best. Water temperature is 22.3°C, air climbs to 23.6°C, and rainfall is almost zero at 0.08 mm/day. If you can catch a light-wind dawn, the water is still crisp and the power is real.
