August: High-Energy Swell With a Low Clean Percentage
August continues the wet-season pattern, with the average swell height holding at 1.4m and the period easing slightly to 13.2s. Swell from the SSW still dominates at 90%, and the SW component provides another 7%, meaning the beach is looking straight down the barrel of the South Pacific groundswell. The numbers get ugly on the wind side: ideal conditions drop to 19%, with persistent SE, SSE, S and SSW winds making the ocean feel jumbled and cross-onshore. Rain sits at 7.86 mm/day, air temperatures average 26°C (22-31°C), and water temperature is 29.2°C. There are 3-5ft (1-1.5m) waves on a regular basis, but only the occasional wind-sheltered, dawn-period session offers anything truly classic.
