Conditions at Piha in August
August: Westerly Wind Battles
August is big but messy. Swell averages 6ft (1.9m) at 13.0s, and the now-equal SW 31.7% and WSW 30.0% split means a very westerly, chunky swell regime. There is plenty of 5-8ft (1.5-2.5m) surf and a notable amount of 8ft+ (2.5m+) energy, but ideal wind frequency drops to just 19%, the lowest since the spring pattern begins. Low-pressure systems and strong westerly winds dominate, creating many blown-out days. Patience is key: when the wind does swing E or NE, the long-period swell lines up so well that it is worth the wait. Water remains cold at 13.8°C with frequent rain.
