Conditions at Cronulla in July
July: Peak Winter Consistency
July is the statistical peak of the surf season at Cronulla. The ideal wind percentage reaches 42%, the highest of any month, with WSW, W and WNW winds combining for over a third of the wind observations. The average period stays at a strong 9.5 seconds and the average height is 5-6ft (1.7m), but the quality is far better than those numbers suggest because the wind is so often offshore.
Swell distribution still centers on SSE and S, with SSW and SW swells also becoming more common as winter deepens. This means plenty of long-period southern hemi groundswell wrapping into the bay. The beaches handle it well, especially on the low tide sandbanks. The downside is the cold: water temp bottoms out at 17.8°C and air temps average 13.8°C, with relatively dry conditions at 1.60 mm/day. For surfers who can handle a bit of chill, July offers the most consistent window of clean, powerful waves all year.
