A 105°F average high does one thing above all else to a scorecard: it compresses your playable window to roughly dawn until the sun is fully high and conditions deteriorate hole by hole. After that, heat stress slows decision-making, inflates scores on longer par-4s where a second shot requires standing in direct sun, and turns a missed fairway into a penalty in baked rough that adds friction to every chip. The low of 78°F means even the overnight round doesn't offer true relief — the course never fully cools, so greens stay firm and fast by first light. With only 2 rain days and peak wind at 11.4 mph (moderate, not disruptive), the air is dry and still enough that the heat is the single dominant variable. Plan your round entirely around it.
June is functionally the city's serious heat entry point. The dryness is genuine — tied for the driest month of the year — so ball flight is consistent and distances run long on sun-hardened turf. Any approach that misses the green runs well past the hole on firm, moisture-starved surfaces, turning routine up-and-downs into two-putt scrambles at best.
Book the earliest available tee time — 6 AM or as close to it as the course allows — since the window before conditions deteriorate is narrow and those dawn slots fill fast in June. At most courses, booking at least a week out is advisable to secure a first-light start before the heat makes later rounds impractical. See how conditions rate hour by hour on our playability scale.
May's 93°F average high makes it meaningfully more comfortable than June — a 12-degree jump from May pushes June from warm-but-manageable into the hot season tier. July adds only 1°F more heat but brings 5 additional rain days as the monsoon season begins, introducing afternoon storm windows that June simply doesn't have. In that sense, June is the hottest dry month — more punishing than May in temperature, but more predictable than July in weather.

It depends entirely on your tee time. With a 105°F average high, afternoon rounds are genuinely unsafe for most players and will damage scores through fatigue and poor decision-making. An early morning round starting at 6 AM is viable — the 78°F overnight low means conditions at dawn are warm but not extreme, and the 2 rain days and 11.4 mph peak wind mean weather won't add complications.
The earliest slots — 6 to 7 AM — are the most contested because the playable window is so narrow at this time of year. With a 105°F average high, most experienced local golfers target dawn tee times, so those slots at popular public courses fill quickly. Booking well in advance is advisable if you want the coolest available starting time.
