August in Scottsdale, AZ: hot season for golf — play early; afternoons are oppressive. Best tee times: tee off before 8 AM to beat the heat.
| Average August Weather | |
|---|---|
| Avg daily high | 104°F |
| Avg daily low | 83°F |
| Rainy days | 7 / mo |
| Avg peak wind | 11.9 mph |
Three numbers define what August does to a round in Scottsdale: a 104°F average high, an 83°F overnight low, and 7 precipitation days. The high is the second-highest of the year, tied only with June, and it shows up on the scorecard as accelerated fatigue, clouded club-selection judgment by the back nine, and irons that heat up in the bag. The low of 83°F means the overnight temperature barely drops, so a 6 AM tee time still starts warm.
The monsoon pattern adds a second variable. August ties July and January for the most precipitation days of the year at 7, and afternoon storms can roll in quickly enough to suspend play mid-round. The 21°F daily swing sounds significant, but nearly all of it happens after dark — by tee time, the relief is minimal. Wind averages 11.9 mph at peak, placing August fifth-windiest on the annual calendar, enough to affect approach shots on exposed desert holes but not the dominant factor here.
Book the earliest available tee time — 6 AM if the course allows — to maximize the cooler window before temperatures climb sharply through the morning. Afternoon slots carry both the peak heat and the highest storm risk from monsoon activity, so a late tee time in August is a double liability for finishing a full round.

August sits nearly identical to July in terms of playing conditions — the average high drops just 2°F to 104°F and precipitation days stay flat at 7, so the scorecard challenge barely changes between those two months. The real shift comes looking forward: September's average high falls to 99°F, a meaningful 5-degree drop, and storm frequency eases to 5 precipitation days, making September noticeably more manageable on the course. August is essentially the last full month where triple-digit heat is the default condition from the opening tee shot.

August is genuinely difficult: the 104°F average high is the second-highest of the year, and 7 precipitation days mean a meaningful chance of a weather delay on any given afternoon. If you can wait, September's average high drops to 99°F with 2 fewer storm days, and October drops further still. That said, early-morning August rounds are playable if you're heat-acclimated and prepared.
August ties for the most precipitation days of the year at 7, and the monsoon pattern concentrates most of that activity in the mid-to-late afternoon. Storms can move from visible to overhead in under an hour, so courses regularly issue horn suspensions without much warning. Booking the earliest available tee time significantly reduces exposure to afternoon monsoon activity.
