August: Summer Windswell Grind Continues
August is essentially a carbon copy of July, with a slight tick up in period. Average swell height stays at 1.3m (4ft), average period is 9.0s, and ideal wind is only 10%. NW continues to dominate at 68.6%, with WNW at 13.9% and NNW at 15.2%, but most of this energy is short-period, mostly windblown swell. NNW and NW winds combine for a massive 64.9% of the wind observations, keeping the surf textured for much of the day. Water temp reaches its annual high of 17.7°C, air temp averages 23.0°C, and precipitation is minimal at 0.12 mm/day. This is the time to bring a groveler and focus on the early windows, because consistent, powerful surf will not return for another month or two.
