August in San Francisco presents a paradox: it is simultaneously one of the driest months of the year — just one precipitation day, tied with June and July — and still firmly in the windiest tier of the calendar at 16.7 mph peak winds. Rain is essentially off the table as a planning factor, yet that doesn't simplify your round. Wind at 16.7 mph will cost or gain you a full club on every exposed approach, and fog-driven morning chill is the hidden variable the numbers understate. The average high reaches 68F with a low of 58F, a tight 10-degree daily swing, but tee times before 8 AM near the coast can feel a few degrees cooler than that high suggests.
Temperatures are comfortable and narrow enough that you won't be layering and shedding all round. At 68F, August is the third-warmest month on the calendar, and a vest at the first tee is usually unnecessary by the back nine. The catch is fog-driven morning chill, so tee times before 8 AM can feel a few degrees cooler than the numbers suggest.
Because rain is nearly a non-issue in August, your booking decision should hinge on wind rather than weather windows — in San Francisco, the afternoon thermal cycle draws cool Pacific air eastward through the Golden Gate gap, meaning courses on the western and northern edges of the peninsula see wind build sharply after midday, so morning slots before 10 AM give you the most manageable conditions. With peak season demand high and just one rainy day to deter anyone, weekend morning tee sheets at popular San Francisco public courses fill faster than the wind data alone would suggest.

August and July are nearly identical on paper — same one precip day, a negligible 1F difference in high temperature, and peak winds just 0.6 mph quieter in August — so you won't feel a meaningful shift between those two months. The real transition comes in September, when the high climbs another 2F to 70F, wind eases by 0.8 mph, and precipitation ticks up to 2 days, making September slightly softer and a touch warmer without sacrificing much dryness.

Peak winds in August average 16.7 mph, which ranks August as the 5th-windiest month of the year here. That falls in the moderate range and is enough to influence club selection noticeably, especially on courses with bay or ocean exposure.
