Most golfers show up in September expecting a slightly cooler version of the Tulsa summer they've been avoiding — and that's partially right. The average high drops to 85°F from August's 90°F, which sounds modest on paper. The real surprise is how much the evenings pull the temperature down: the average low sits at 68°F, creating a 17-degree daily swing that makes morning tee times genuinely comfortable even when afternoons stay warm.
The second surprise is the weather window itself. September ties for the second-driest month of the year at just 9 precipitation days, a sharp drop from August's 13. Wind peaks at 10 mph, the second-calmest reading of any month. Golfers who wrote off September as "still summer" are often the ones who end up booking last-minute after a friend calls from the 7th fairway.
With the 17°F daily temperature swing, an 8–10 AM start lets you finish 18 holes before the afternoon high pushes into the mid-80s — book that window as soon as you have a date, because September's reputation for comfort is no longer a secret among locals. Midweek slots open up more than weekends, so if your schedule is flexible, Tuesday through Thursday morning rounds carry the least competition for tee times. See how conditions rate hour by hour on our playability scale.
September is a clear step down from August's 90°F average high and 13 wet days — four fewer rain days alone makes a meaningful difference in scheduling. Compared to October, September runs 12°F warmer on average, with wind peaking 2.3 mph calmer and nearly the same number of precipitation days (9 vs. 10). If heat tolerance is your only concern, October wins; but if you want calm air and dry fairways, September gives up very little.

September averages 9 precipitation days, tied for second-fewest of any month in the year. That's four fewer wet days than August, so the odds of a rain-out are relatively low.
