September sits at the tail end of Jacksonville's hurricane season, and that context shapes every round: you get marginally better conditions than August on paper, but the rain burden is still severe enough to demand a plan every single day. Precipitation days drop from August's 28 to 22, and the average high eases from 88°F to 85°F — improvements, yes, but 22 rain days still means roughly three-quarters of September afternoons carry a real storm threat. Wind comes in as the 5th-calmest month of the year at 11.1 mph peak. That's about the only consistent break September offers.
The practical reality is that morning tee times are nearly mandatory. Keep your bag cover accessible and build in flex time for a lightning delay if you can't finish before midday. Late-summer storms can be brief but intense, so check the course's suspension policy before you go out — a hold can add an unpredictable stretch to any round. Rounds that start at first light can often finish ahead of the worst weather, but on roughly 22 of the month's 30 days, some form of rain is in play.
Book the earliest available slot — ideally before 8 AM — because afternoon storm risk is high on most September days. Mid-afternoon weekend tee times are especially risky and worth avoiding if you have any flexibility. See how conditions rate hour by hour on our playability scale.
September is meaningfully drier than August, which averaged 28 precipitation days — six more than this month — making August the harder stretch to plan around. Moving the other direction, October drops to just 14 rainy days and cools to a 79°F average high, a six-degree improvement that makes it a considerably more reliable month for Jacksonville golf. Wind ticks up marginally into October at 11.5 mph versus September's 11.1 mph, so rain and temperature are really the only variables shifting the calculus.

Climate normals put September at 22 precipitation days, making it the fourth-wettest month of the year. That doesn't mean 22 full washouts, but it does mean measurable rain falls on roughly three-quarters of the days in the month, mostly as afternoon convective storms.
October is noticeably better on almost every measure that matters for golf. It averages eight fewer precipitation days (14 vs. 22), and the average high drops from 85°F to 79°F, which puts it squarely in the comfortable range. October is marginally windier at 11.5 mph versus September's 11.1 mph, but that small difference is far outweighed by the gains in rain and temperature.
