August in San Diego, CA: peak season for golf — great conditions and a wide playing window. Best tee times: mid-morning through early afternoon.

August suits two very different golfers in San Diego. The traveling visitor who has planned around ideal weather will find nearly everything they came for: a 78°F average high, just 2 rainy days for the month, and a 12°F daily swing that keeps mornings in the low-to-mid 60s — comfortable before the marine layer fully burns off. Conditions land squarely in the site's ideal temperature band, and at 11.8 mph peak wind it stays manageable, though not the calmest the calendar offers.
The local regular, by contrast, knows August is the hottest San Diego gets — tied for the year's warmest average high — and that coastal courses can see persistent morning fog push tee times later than planned. For regulars who prefer the breezy, slightly cooler feel of early summer, July may actually be the sweeter spot. But for out-of-towners with a fixed vacation window, golf in San Diego in August delivers a reliable, low-rain experience that's hard to fault.
Book early-morning slots cautiously in August: marine layer fog along coastal and canyon courses routinely delays play past the 6 AM open, so a 7–8 AM tee time often works out better than the first slot of the day. Demand is at its annual peak, so securing weekend tee times more than a week out is advisable at the most-sought coastal tracks. See how conditions rate hour by hour on our playability scale.
July is fractionally cooler at 75°F and records zero precipitation days, making it marginally drier and a touch less warm than August's 78°F high and 2 rain days. September matches August's 78°F average high and 11.8 mph peak wind exactly, but edges up to 3 precipitation days, so August holds a slim dryness advantage heading into fall. The three-month stretch is remarkably consistent — the biggest single jump is the +3°F warming from July into August.

August is peak season here, with an average high of 78°F and only 2 rainy days — the second-driest month of the year. Course conditions are generally firm and fast, which suits visitors who want predictable weather. The trade-off is that it's the hottest month on the calendar and courses are at full demand, so expect higher rates and fewer last-minute tee times.
The marine layer that rolls in overnight frequently keeps coastal and hillside courses socked in until mid-morning, and some venues will hold or delay the first groups until visibility clears. Planning your tee time for 7:30–8:00 AM rather than first light reduces the risk of a fog delay. Inland courses away from the coast typically burn off earlier and are a safer bet if you need an early start.
