September in Knoxville, TN: shoulder season for golf — playable with smart tee time selection. Best tee times: morning before noon for the most comfortable round.
| Average September Weather | |
|---|---|
| Avg daily high | 83°F |
| Avg daily low | 64°F |
| Rainy days | 12 / mo |
| Avg peak wind | 7.6 mph |
September in Knoxville tends to get underestimated. Golfers who had a rough August often assume the shoulder-season badge means genuinely mild conditions, but the average high is still 83°F — only 3 degrees cooler than August — so the heat doesn't simply vanish. What does change sharply is the rain: August delivers 17 precipitation days, and September drops to 12, making it the 3rd-driest month of the year. Peak wind comes in at just 7.6 mph, the 2nd-calmest of any month. The combination of fewer interruptions and calmer air makes September play better than its temperature suggests.
The other thing that catches people off guard is the 19°F daily swing between the 64°F morning low and the 83°F afternoon high. Early tee times feel almost fall-like with cool air, then the back nine can warm up fast. Layering isn't just an October strategy — it applies here too.
Book a morning tee time — ideally at or shortly after 6 AM — to take advantage of the 64°F low before temperatures climb toward 83°F; afternoon slots risk the same heat discomfort that defines August. With only 12 precipitation days spread across the month, there are more playable windows than most golfers expect coming off a rain-heavy August. See how conditions rate hour by hour on our playability scale.
September improves meaningfully on August, cutting five rainy days and arriving with a cooler average high of 83°F versus 86°F, while winds stay essentially the same. Compared to October, September runs 11 degrees warmer and adds two more precipitation days, so golfers who want milder temperatures should plan to return in October, but those who don't mind the heat will find September slightly wetter. October's wind nudges up by 0.6 mph — a negligible difference, but September edges it out as the calmer month.

Yes, and often better than visitors expect. With only 12 precipitation days, it's the 3rd-driest month of the year, and peak winds average just 7.6 mph — the 2nd-calmest of any month. The main caveat is the average high of 83°F, which means afternoon rounds can still be warm; morning tee times are the straightforward fix.
September sits in a transitional spot: it's 11 degrees warmer than October and carries two more rainy days, but it's noticeably calmer and drier than August. Golfers who want genuine fall temperatures should wait for October's average high of 72°F, but those who book September will still find fewer weather interruptions than they likely had all summer.
