Conditions at Castaways in August
August: Swell Direction Perfection, Wind Frustration
August sees the most concentrated swell direction of the year, with SSE alone delivering a massive 55.7% of the waves. The average height holds at 1.7m (5.5ft), and periods in the 11.1s range guarantee plenty of power. But the wind remains the Achilles' heel. Ideal conditions clock in at just 18%, with SE, S, and SW winds commonly ruffling the surface. The short intervals of lighter wind are the only times Castaways truly shows its potential. For the travelling surfer, this is usually best avoided unless you have flexible timing and are willing to chase early mornings. Water temps stay at 29.4°C, with similar rainfall to July.
