July: Mid-Winter Consistency and Heavy S-SSW Groundswell
July holds the same peak-season energy as June. Average swell is 1.9m (6.2ft), period 12.0s, and ideal wind sits at 56%. The swell distribution is remarkably similar: SSW 32.7%, SW 17.0%, S 14.5%, SSE 7.4%, with the SSW direction carrying the most 1.5-2.5m (5-8ft) energy. The wind rose shows plenty of WNW/NW/NNW offshore flow, balanced against WSW and W cross-shore/onshore influence. The difference in July is that the long-period S/SSW groundswell is often heavier and more consistent, and the colder winter air keeps the seabreeze weaker when high pressure is nearby. Expect pumping, well-formed surf whenever a strong frontal system passes south of the continent. Water temperature cools to 17.8°C, air temperature averages 15.3°C, and precipitation remains modest at 0.95 mm/day.
