Conditions at Cronulla in August
August: Late Winter Gems
August holds onto much of winter's momentum, with ideal offshore winds still at 38% and an average wave period of 9.2 seconds. The swell mix begins to broaden: SSE and S remain dominant, but NE and ENE swells recover slightly as the Pacific high starts to strengthen. Average wave heights remain around 5ft (1.6m), with a good spread of 3-8ft (1-2.5m) surf.
West and north-west winds are still frequent enough to keep Cronulla clean, especially at dawn. The slightly shorter average period and the return of easterly trade energy mean you get a mix of lined-up S/SE groundswell and punchier E/NE swell lines. Water temperature stays cold at 17.8°C, air average is 14.4°C, and rainfall is low at 1.75 mm/day. August often delivers those crisp, glassy winter mornings that make the whole session worthwhile.
