Direction-wise, NW and WNW make up over 90% of the swell, but the energy is mostly in the 2-5ft (0.5-1.5m) range, with the biggest share sitting around 2-3ft (0.5-1.0m). The wind is ideal 43% of the time, the best summer score, which helps when the swell lines up. Early mornings remain your best bet before the NNW/northwesterly seabreeze builds. Water temp is 16.9°C, air temps reach an average of 20.4°C, and rainfall is scarce at 0.75 mm/day. Expect smaller, slower, crumbly waves at the beach, more summer fun than serious high-performance surf.
