September's numbers in St. George tell a specific story once you put them on the course. A 93°F average high sits well above the 60–80°F comfort window, which means morning rounds finish before the heat peaks and afternoon rounds don't start — full stop. The upside is real, though: only 2 precipitation days make this the second-driest month of the year, so rain delays are nearly off the table. Peak wind checks in at 9.4 mph, comfortably in the moderate range, so it won't be reshaping your shot shape the way a desert afternoon blow can.
The 24°F daily swing between the 69°F low and 93°F high is the number that actually runs your tee time decision. Early morning tee times — think 6 to 7 AM — put you on the green in genuinely playable air. Wait until 10 AM and you're grinding through 85°F climbing heat. Club selection stays fairly clean with calm-ish wind, but the heat thins the air density enough that your distances may run slightly longer than home.
With a 93°F average high, book the earliest available slot — ideally a 6 or 6:30 AM start — to complete 18 holes before temperatures clear 85°F. Mid-day and afternoon tee times in September routinely push past 90°F by the back nine, which adds real fatigue and can affect putting pace and club selection.

September drops 7°F off August's brutal 100°F average high and cuts precipitation days in half from 4 to 2, making it a meaningfully more manageable month to play. Wind also eases by 1.5 mph from August's 10.9 mph. October takes the temperature improvement much further, falling another 14°F to a 79°F high that fits squarely in the ideal range, though it adds one precip day back and only trims 1.4 mph off the wind.

It depends entirely on when you tee off. The average high hits 93°F, which is above comfortable playing range, but mornings start near 69°F and only 2 days see any precipitation. A 6–7 AM tee time gives you a full round in manageable conditions before the heat peaks.
October is the stronger playing month by a clear margin — its 79°F average high sits inside the ideal 60–80°F window, 14°F cooler than September's 93°F. Wind drops another 1.4 mph to 8 mph in October, though precipitation ticks up by one day to 3. If flexibility allows, October gives you a full day's worth of comfortable tee times rather than a narrow morning window.
