Twenty-seven rain days in a month sounds alarming until you understand what that number actually does on the course. In Naples in September, most of that precipitation falls as short, intense afternoon storms rather than all-day soakers — but with 27 days in 30 carrying measurable rain, the odds that your round stays completely dry are slim. An 88°F average high means heat stress is real: carry times slow down, grips get slippery, and mental focus erodes faster than the scorecard suggests. The 75°F overnight low offers no relief by morning tee time.
The 13°F daily swing matters tactically. A morning round started at the low end of that range plays more comfortably than an afternoon finish baking toward 88°F. Wind sits at 9.8 mph peak — calm enough that it won't add strokes directly, but on humid September air, even a light breeze carries moisture that affects ball flight less than your stamina.
Book the earliest available tee time — ideally at or just after 6 AM — to get the front nine completed before afternoon storm cells develop; with 27 rain days in the month, waiting for an afternoon window is a losing bet. Courses often move faster in the morning heat than you'd expect because other golfers are doing the same math, so reserve a full week in advance rather than day-of.

September trims three rain days off August's 30, a modest improvement that still leaves it among the wettest months on the calendar — tied with June for third-wettest. The real shift comes heading into October, which drops to just 19 rain days, an eight-day reduction that makes a meaningful difference for uninterrupted rounds. Wind ticks up slightly each month, from August's 9.4 mph through September's 9.8 mph to October's 11.2 mph, so September remains the calmer side of that transition.

September sits in the Variable tier for a reason: the 88°F average high and 27 rain days make comfortable, uninterrupted golf genuinely difficult. That said, tee times before 9 AM often yield a playable window before afternoon storms build, and the 9.8 mph peak wind is among the calmest of the year, so when conditions cooperate the course plays without much wind penalty.
The 27-day precipitation figure means rain occurs on 90% of September days on average, but the majority of those events are convective afternoon storms that can pass in under an hour. A full morning round is often completable; scheduling a late-afternoon tee time in September carries a high likelihood of a weather delay or an incomplete round.
