August: Warm, Lumpy, and Still Catching Real Southern Hemi Swell
August keeps the post-summer swell furnace lit. Average height stays at a meaty 1.6m (5.2ft) with a 13.2s period. The direction mix is again dominated by SSW (63.1%) and S (27.0%), with SW adding 6.1%. There is plenty of 1.5-2m (5-6.5ft) swell (42% of the total) and occasional 2-2.5m (6.5-8ft) energy from the SSW. Troncones will be far from flat, but the quality depends entirely on the wind.
August sees the strongest SE wind signal of the year - SE winds reach 11.7% of all observations, with SSE at another 8.2% - so expect plenty of lumpy, cross-shore chop when those onshore regimes set in. Ideal winds are 37%, and rain is at 6.48 mm/day with water temp peaking at 30.8°C. This is the classic 'offshore in the morning, messy by lunch' scenario. Score the dawn windows and you'll find long-period SSW swell wrapping into the bay with real power; wait until afternoon and you'll often get windslop.
