Conditions at Sunrise in August
August: Late Winter - A Touch Bigger, A Little More Wind
August is still prime time, though the quality begins to soften. The average swell height rises to 1.9m (6.2ft), the biggest of winter, but the period drops slightly to 10.0s-still in the powerful long-period bracket. The ENE swell channel comes alive (16%), with a large block of 1.5-2m and 2-2.5m waves; combined with E (11.5%) and SE (10.1%), there's plenty of directionally favorable energy. The S (19.9%) and SSE (16.2%) remain the biggest single contributors. The wind story changes a little: NE wind rises to 12.8%, ENE to 6.7%, and the ideal wind score falls to 39%. WSW-W-NW offshore flow is still around 15%, so there are plenty of clean windows, but you need to pick your days. Water temp is 21.0°C, air 18.8°C, and only 0.81mm/day of rain falls. The bigger, more easterly swells can produce some excellent, rippable walls before the spring trade winds return.
