September in Baton Rouge sits in an awkward middle ground that suits different golfers for different reasons. Locals who play year-round will recognize it as a marginal improvement over August — the high drops to 87F from 91F and rain days ease slightly from 18 to 16 — but it's still hot, humid, and wet enough that most regulars tee off at dawn and pack it in before noon. The heat index regularly pushes past what the air temperature suggests, and with 16 precipitation days, you're more likely than not to encounter a shower on any given round.
For the traveling golfer, September is harder to recommend unless flexibility is built into the trip. October offers a far more comfortable window — seven fewer rain days, a 7-degree drop in the high, and manageable afternoons. That said, if a travel schedule lands you here in September, early-week tee times and morning rounds give the best odds of staying dry. Wind stays calm at 9.9 mph, so at least the ball flies cleanly when conditions cooperate.
With 16 precipitation days and afternoon heat still peaking at 87F, book the earliest available tee time — ideally before 8 AM — and target weekday slots when courses are less likely to be backed up by weekend crowds who also scrambled for morning windows. Last-minute openings mid-week are common as locals bail on afternoon rounds, so checking same-day availability the evening before can pay off. See how conditions rate hour by hour on our playability scale.
September's 87F high and 16 rain days are a modest step down from August's 91F and 18 rain days, but the improvement is incremental rather than transformative. The real change comes in October, which cuts rain days by seven and drops the average high another 7F to 80F — a threshold where afternoon rounds become genuinely comfortable. Wind is effectively flat across all three months, ranging only from 9.8 to 10.4 mph.

September is workable but not ideal for visiting golfers. The average high is 87F, humidity is high, and 16 precipitation days make rain a near-daily possibility. Travelers who can shift the trip to October will find seven fewer rain days and a 7-degree cooler high, which makes a meaningful difference for afternoon rounds.
Morning tee times before 8 AM are the practical standard for locals in September — temperatures are closer to the 71F overnight low, and convective storms typically build later in the day. By mid-afternoon, heat and the probability of a shower both climb sharply, making early starts the most reliable way to complete a full round.
