August: The Dog Days of Surf

August remains in the summer surf doldrums, but there is a slight pulse compared to July. Average swell height is 3.5ft (1.1m) and period is 8.5s, still short-period and wind affected. W swell is incredibly dominant at 48.2%, with WNW at 19.8% and WSW at 13.0%; the sea state is almost always westerly, yet rarely powerful. Most waves are in the 2-5ft (0.5-1.5m) range, and the bigger days are the exception. Ideal wind frequency is only 17%, and the classic summer pattern of W/NW onshores and afternoon sea breezes limits quality. The saving grace is the warmest water of the year at 17.5°C, with air temps averaging 16.7°C and precipitation at 2.77mm/day. When a late-season depression dips south and the wind swings offshore, Watergate Bay can still offer surprisingly fun summer peaks.
