Rain is the defining variable for golf in Port St. Lucie in September. With 27 precipitation days on average, you're looking at rain on nearly every day of the month — third-wettest of the year. That doesn't mean 27 washed-out rounds, but it does mean almost every tee time carries real interruption risk, typically from afternoon convective storms that build fast and clear out within an hour.
Temperatures sit at 87F high and 74F low, a 13-degree daily swing that keeps mornings marginally more comfortable than the peak summer weeks. Winds average a peak of just 9.6 mph — second-calmest month of the year — so when you do get a dry window, conditions are genuinely benign. The challenge is finding that window consistently. Early morning rounds, booked for the first tee time available, give you the best odds of finishing before the afternoon cycle kicks in.
Book the earliest available tee time — ideally 6:30 to 7:30 AM — since September's convective storms typically develop after midday and the window before them is real. Afternoon slots carry consistent interruption risk on most days in September, so later bookings are a gamble even when the morning looks clear. See how conditions rate hour by hour on our playability scale.
September edges slightly drier than August, shedding 2 precipitation days (27 vs. 29) and cooling a touch from 89F to 87F highs — a marginal improvement, not a meaningful one. The real shift comes heading into October, which drops to 20 rain days and cools further to 83F, making October a noticeably more reliable month to play. If your schedule has any flexibility, October represents a genuine step up in playability.

It's workable but demanding. With 27 average precipitation days, nearly every round faces some interruption risk, and the 87F heat adds fatigue on top of that. Early morning tee times improve your odds considerably, and the 9.6 mph average wind means conditions are calm when the weather cooperates.
September sits in the heart of South Florida's wet season, and afternoon convective storms are a near-daily occurrence — the 27 rain days back that up. They tend to arrive fast, drop heavy rain for 30–60 minutes, then pass, but lightning delays will halt play. Most courses will hold players in the clubhouse until the cell clears, so build extra time into your schedule.
