Conditions at Impossibles in August
August: Same Size, Slightly Cleaner
August keeps the same average height and period as July-7.2ft (2.2m) at 14.4s-but the wind character shifts subtly. The ESE flow is still dominant at 54.2%, yet the 20-30kph share drops to 28.3% and the lighter 10-20kph band increases. Ideal wind climbs back to 49%. Swell direction becomes more SSW-weighted: SSW 49.7%, S 24.3%, SSE 5.3%. This means very high volumes of 5-8ft (1.5-2.5m) surf. With the calmer trade winds, Impossibles offers a better chance of clean, lined-up sets than in July. Rainfall stays low at 0.65mm/day, water temperature continues to fall to 26.7°C, and the air is a brisk 25.5°C. Solid late-winter vibes.
