The one variable that defines golf in San Jose in August is rain — specifically, the near-total absence of it. With just one precipitation day for the month (tied with June for the driest of the year), you can book a tee time almost any day without a second thought about weather cancellations. Conditions are about as reliable as they get.
That reliability comes with a tradeoff. The average high hits 86°F, the hottest reading of the year, and while mornings start comfortably at 60°F, the 26-degree daily swing means afternoon rounds can feel noticeably warmer than the early light suggests. Peak winds reach 14.3 mph — the second-windiest month of the year, tied with July — so breezes off the bay will factor into club selection, particularly on exposed holes in the midday hours.
Early morning tee times (6–8 AM) let you start in the comfortable 60°F low before the heat builds toward the 86°F afternoon peak. Wind tends to pick up through midday, so finishing the back nine before early afternoon also helps keep those 14.3 mph gusts from compounding the heat challenge. See how conditions rate hour by hour on our playability scale.
August is nearly identical to July in wind (both 14.3 mph) but drops to just one rainy day versus July's two, making it marginally the safer booking of the two. Stepping into September, rainfall jumps by three days and peak wind eases slightly to 13 mph, so September trades some of August's dryness for a modest cooling trend — the average high falls to 84°F. If dry conditions are your priority, August has the edge; if you'd prefer cooler afternoon temperatures, September closes that gap quickly.

The average high of 86°F is warm but manageable if you tee off early. Morning lows sit at 60°F, so a 7 AM start gives you several comfortable hours before temperatures climb. Afternoon rounds in full sun are the main concern, not the calendar month itself.
The South Bay sees less dense fog than coastal courses farther west, but cooler marine air can still produce low cloud cover in the early hours before burning off by mid-morning. With only one precipitation day expected all month, fog is more of a visibility nuisance than a round-canceling event.
