August: Late-Winter Swell Train with Offshore Grooming
August keeps the winter swell train rolling. Average height still sits at a strong 9ft (2.8m), and the period remains long at 12.3s. Ideal offshore wind drops slightly to 39%, but the dominant wind directions still favor clean conditions: WNW (11.1%), NW (15.2%) and NNW (15.5%) are all well represented. The swell window is slightly broader, with SW (18.2%), WSW (9.2%) and SSW (9.2%) combining with S (3.9%) and W (2.8%) to produce a steady diet of west-southwest to south groundswell. Many sessions will offer powerful 6-10ft (1.8-3.0m) waves, and the longer Westerly component often means more consistent bowls and a wider variety of peaks up and down the bay. Water temps bottom out at 14.8C, air averages 14.0C, and rainfall is still significant at 2.90mm/day. Late August is a great time to score before the spring transition begins.
