August: Big Winter Groundswell Continues
August holds onto the peak of the winter swell window. The average swell height remains at 2.7m (9ft) with an average period of 13.8s, so the ocean is still running at full capacity. SW swell again leads the way at 24.1%, with SSW at 13.0% and WSW at 4.8%. The 2-2.5m (6-8ft) range is the dominant bracket, and there is a healthy dose of waves over 2.5m (8ft) to keep things serious.
Ideal offshore wind is 11% of the time, just below July but still far better than summer. SE and SSE winds remain common at 12.0% and 11.8%, but the W to NW windows are frequent enough to give regular clean-session chances. The cooler water at 21.0°C and air temperature of 18.6°C confirm full winter conditions. Rainfall eases to 1.77 mm/day. This is a solid month for experienced surfers chasing powerful, long-period waves.
