August: Late Winter Strength, Slightly Smaller Windows
August sees the winter swell machine still pumping, but with slightly shorter fetch windows. Average wave height is 5-6ft (1.8m), the highest of the year, while the period settles at 10.2s. The swell rose is broader: ENE and E take up 14.2% each, ESE and SE add another 23.1%, and SSE/S combine for 37.5%. Big-wave potential remains strong, with the S direction posting 6.3% in the 6-8ft (2-2.5m) category and a touch above 8ft (2.5m). ENE also contributes 3.1% at that size, a sign of a very active ocean.
Wind is still favorable but less consistently so. Ideal windows drop to 41%, while NE/NNE flow expands to 30.7%, and SSW adds 16.1%. The onshore E/ESE/SE/SSE sector remains low around 8%, so there are still plenty of clean days. Water temperature reaches its coldest at 21.3°C, air averages 19.9°C, and rainfall is dry at 1.06mm/day. Late winter in August is a solid pick for quality before spring transitions kick in.
