July in Phoenix, AZ: hot season for golf — play early; afternoons are oppressive. Best tee times: tee off before 8 AM to beat the heat.

A 107°F average high is not a minor inconvenience — it is a scorecard problem. At that temperature, a Phoenix fairway bakes like asphalt, grip tape softens, and your body starts burning calories just standing over a putt. The low of 85°F means even a 6 AM tee time gives you little relief; the overnight heat never breaks far enough to reset conditions. July also brings Phoenix's monsoon season into its early stride, meaning those 6 precip days aren't gentle drizzles — they're afternoon thunderstorms that can halt play entirely. Add the year's strongest peak winds at 13.6 mph and you have a month where every stat on the table is working against your number.
Practically speaking, expect firm, fast greens running faster than their stimpmeter rating because the surface moisture is gone by mid-morning. Approach shots that would check up in October will release and chase past the hole. Club distances change too — hot, less-dense air gives the ball extra carry, so your 7-iron yardages from cooler months need recalibration.
Book the absolute earliest available tee time — 6 AM if the course offers it — and plan to be off the course before 10 AM, when surface temperatures are already climbing well past 100°F. July's afternoon monsoon window also makes late-day rounds a gamble on weather holds, so morning slots serve double duty against both heat and storm risk. See how conditions rate hour by hour on our playability scale.
June is actually two degrees cooler on the high and has only 1 precip day compared to July's 6, making it the drier, marginally more playable of the two extreme-heat months. July to August drops the average high by 3°F to 104°F, but precipitation ticks up another day to 7, so August trades a small temperature benefit for slightly more storm interruption risk. Wind eases by 1.2 mph heading into August, which is a minor relief but not enough to meaningfully change how the course plays.

It can be done safely only with strict time management — finish before 10 AM, stay hydrated with electrolytes, and never play through dizziness or cramping. With a 107°F average high and an overnight low that only drops to 85°F, the heat load is real and unrelenting even at sunrise.
Yes — July is one of Phoenix's wetter months, tied for second at 6 precipitation days, because the North American monsoon typically kicks into gear this time of year. The rain usually arrives as intense afternoon thunderstorms rather than all-day drizzle, which is another reason morning tee times are strongly preferred.
