August: Persistent Winter Onshore Flow
August holds the winter line with an average swell height of 1.9m (6.2ft) and a 13.0s period. Swell direction is once again dominated by SSW (71%) and S (17%), placing a lot of long-period energy squarely on La Isla's southwest exposure. The wave-height distribution shows a strong concentration in the 5-8ft (1.5-2.5m) range, so there is no shortage of size.
True offshore flow stays at 0% for the month. Instead, S (38%) and SSW (38%) winds form a relentless onshore regime, with SSW and SW breezes regularly blowing 10-20kph. That combination makes for stormy, textured conditions despite the excellent underlying swell. Keep expectations low and chase any rare morning glass-off.
Air temperatures bottom out around 12.2-23.8°C, rain is minimal, and water temperature drops to 15.5°C. Cold, powerful and mostly wind-blown - August is a tough month at La Isla.
