Most golfers expect September to be a relief from St. Augustine's brutal summer heat — and they're partially right. The average high drops to 83°F from August's 86°F, which sounds like progress until you're standing on the 12th tee at noon realizing the low overnight was 75°F. That narrow 8°F daily swing means the air never really cools off, and humidity stays locked in.
The bigger surprise is the rain. September is the 3rd-wettest month of the year here, with 23 precipitation days — only four fewer than August's peak of 27. Golfers arriving with visions of late-summer deals and emptier courses often find themselves reshuffling afternoon rounds around storm cells. Morning tee times aren't optional this month; they're essential. The winds, at 12.1 mph peak, stay manageable — fourth-calmest of the year — so at least the coastal holes won't punish you there.
With 23 rain days and afternoon convective storms common, book tee times between 6 AM and 10 AM to maximize the window before afternoon buildups arrive. September courses are less crowded than peak season, so early slots are typically available even with short notice — but don't gamble on a midday start expecting to finish clean. See how conditions rate hour by hour on our playability scale.
September improves on August by dropping four precipitation days and cooling the average high by 3°F, but the fundamental playing conditions remain demanding. The real shift comes in October, when the high falls another 5°F to 78°F and rainy days drop sharply by seven to just 16 — a meaningful change. If your schedule has any flexibility, October is the month that actually delivers on what September promises.

September sits in a Variable tier for a reason — the heat and rain haven't fully cleared yet.

If you're targeting fall golf specifically, September is workable with early tee times, but October is a noticeably better experience.
