August: Late-Summer South Swell Windows
August brings a subtle improvement-ideal wind creeps up to 29% as the thermal trough begins to weaken. Swell is still small, averaging 2-3ft (0.8m), but the 12.5s period gives the persistent SSW/SW groundswell a bit of push. The wave rose shows SW at 38.7%, WSW at 38.6%, SSW at 12.4%, and W at 9.9%. Afternoon onshore winds still dominate, especially WSW at 20.3% and SW at 16.2%, but morning conditions are more workable. Water temperature peaks near 17.0°C, air temps are warmest on average at 22.1°C, and precipitation drops to 0.02mm/day. This is the month for early high-tide bowls and small waves on the long-period south swell.
