Conditions at Zavial in August
August: Small Summer Leftovers
August looks very similar to July, with a few extra clean windows. Average swell remains 4-5ft (1.2-1.5m), period 8.7 seconds, and NNW and NW swells account for nearly 89% of the mix. Direct south and southwest swell is still non-existent (0.0%), meaning the beach relies almost entirely on short-period windswell wrapping around the cape. Winds are still dominated by NNW (47.1%) and NW (25.3%), but lighter speeds help ideal conditions edge up to 32%. Water peaks at 19.1°C, air highs can reach 33.3°C, and rain is a rare 0.10mm/day. For a longboard or a groveler, there are plenty of fun morning waves - but it is about quality of life, not quality of surf.
