May sits at the hinge point of Phoenix's playable window and the brutal summer ahead. Coming out of April's mild 87°F highs, you gain 9°F arriving in May — enough to push afternoons well past comfortable territory at 96°F. Mornings, though, are a genuine asset: lows of 69°F mean a 6 a.m. tee time starts in legitimate comfort before the heat builds. With zero recorded precipitation days, May is the driest month of the year, so weather cancellations simply aren't a concern.
The tradeoff is wind. At 13.3 mph peak, May is the third-windiest month on the calendar — up 0.7 mph from April — which can affect shot shape more than the stats table suggests on exposed desert layouts. That wind does provide minor relief from the heat, but plan your round to finish before noon if possible. Afternoon ball-in-hand conditions are not a comfort issue; they're a safety one.
With zero rain days and heat peaking by early afternoon, the only viable window is first light — book the earliest available tee time, ideally 6–7 a.m., and expect to be done by 10 a.m. to avoid the worst of the 96°F afternoon highs. Afternoon twilight rates may look appealing on price but carry genuine heat-risk at this time of year in Phoenix. See how conditions rate hour by hour on our playability scale.
April's 87°F highs and one rainy day make it the softer, more forgiving option — May's 9°F jump to 96°F is the clearest signal that the hot season has arrived. Heading into June, the heat climbs another 9°F to a 105°F average high, lows jump to 78°F, and a precipitation day reappears, so May actually offers the last stretch of zero-rain golf before the monsoon cycle begins building. Wind barely changes — just 0.1 mph separating May from June — so that factor alone won't guide your decision between the two months.

← April in Phoenix, AZ • June in Phoenix, AZ →
At an average high of 96°F, May is manageable only if you tee off early — 6 to 7 a.m. is the practical ceiling for comfort and safety. By comparison, June averages 105°F, so May is the last month before conditions become genuinely dangerous for afternoon rounds. Stick to morning play and the heat is a known factor, not a dealbreaker.
Based on 2020–2024 climate normals, Phoenix records zero precipitation days in May, making it the driest month of the year. You won't need to factor in weather delays or wet fairways the way you might even in April, which averages one rainy day. That said, the Arizona desert can produce isolated afternoon dust events, so check local forecasts the morning of your round.
