ICHETUCKNEE SPRINGS · SEPTEMBER · FLORIDA
The spring water has no season. That is the reason a September page exists at all: the river stays what it is, and the sky over it changes every four weeks. NOAA’s normals put the air at an average high of 88.0°F in September against 89.9°F in August, with rainfall down from 8.10 inches to 5.82. Slightly cooler afternoons, four fewer wet days, and the same clear water running under the cypress.
Most visits are a day trip with a long drive attached, and a weekend works if you want two mornings at the launches instead of one. The figure that decides a September Saturday is not an opening hour but a parking count: the state inventories 909 spaces, and when the lot fills, the gate closes. Our Ichetucknee Springs guide handles the park in general. The question here is the date.
THE MONTH AT A GLANCE · ICHETUCKNEE SPRINGS · SEPTEMBER
September hands you August’s water with roughly three quarters of August’s rain, on a spring whose temperature has no season and an afternoon that still climbs to 88.0°F.
AVERAGE HIGH 88.0°F · 5.82 INCHES OF RAIN · 7.6 WET DAYS · 909 PARKING SPACES
Go for: tubing and paddling with 2.28 inches less rain than August, four launches, 2.8 miles of paddling trail and 4.2 miles of hiking trail.
Think twice before: booking a non-refundable week, since hurricane season peaks around September 10, and before driving without calling: we could not read the park’s fee or hours.

The short version of the date question: the air comes down from August by 1.9 degrees during the day and 3.1 at night, the rain drops by 2.28 inches, and the water you drove for does not move at all. Every normal below is measured at a NOAA station 27 miles from the springhead, because there is no official thermometer at the vent.
Ichetucknee Springs weather in September: average highs, lows and rain days
| Measure | September |
|---|---|
| Average high | 88.0°F |
| Average low | 69.8°F |
| Rainfall | 5.82 in |
| Days with 0.10 in or more | 7.6 |
| Days with 1.00 in or more | 1.9 |
| Daylight on Sept 15 | 12 hr 22 min (7:14 a.m. to 7:37 p.m.) |
Every figure here comes from one instrument, and it is not at the springhead. NOAA NCEI’s 1991 to 2020 monthly normals for station USW00012833, Cross City AP, sit about 27 miles (44 km) away and describe the air: average high 88.0°F, average low 69.8°F, 5.82 inches of rain across the month. Station normals like these come from a real thermometer with a real record rather than from a reanalysis grid cell, and they still say nothing about the water under the tube.
Measurable rain lands on 7.6 days in an average September at that station, counting days of 0.10 inch or more, so about one day in four. Of those, 1.9 days deliver an inch or more, meaning roughly two genuine soakings in a thirty-day month. Florida’s wet season runs May through October with its near-daily afternoon storm pattern, as our season guide sets out, so the rain tends to arrive after lunch rather than cancel a 9 a.m. float.
The gap between 88.0°F and 69.8°F is 18.2 degrees, and one visit can hand you both ends. A dawn arrival in a wet swimsuit is colder than most people expect at this latitude, and the walk back to the car at 2 p.m. is the opposite problem. Pack a dry shirt and a towel you can reach without unpacking the trunk, a rain shell for the afternoon, and a dry bag for phone and keys if you plan to float.
September 15 brings 12 hours 22 minutes of daylight, sunrise at 7:14 a.m. and sunset at 7:37 p.m. local time. That still leaves a long evening after a late float, though the light under the canopy goes soft well before the sun is gone. By the last week of the month you have lost more of it, which matters mostly if your itinerary ends with a drive home on two-lane roads.
How warm is Ichetucknee Springs in September?
The month averages 88.0°F by day and 69.8°F before dawn at the Cross City station, an 18.2 degree swing inside every 24 hours. Those are averages, not the hottest afternoon you might draw: a normal smooths thirty Septembers into one, and individual days run above and below. Set against August at 89.9°F and October at 82.2°F, September is the first step down, and most of the drop is still ahead of it.
Morning is the only part of the day that asks for a layer: a hoodie in the car for the drive in, off before you reach the water. Afternoons want shade, a hat and more water than you packed. Traveling with children, respect that 69.8°F dawn figure, because a small body coming out of spring water at 8 a.m. cools quickly. Our family guide covers the rest of the Florida logistics.
Freezing is not a September question at this station: the monthly average low sits nearly forty degrees above it, and we found no freezing-day count in the normals we read. The water is a different matter, and an honest one. We could not verify a measured temperature at the vent, so no water figure appears in our numbers. What the state does say is that the spring itself has no season, while the air above it has a strong one.
How busy is Ichetucknee Springs in September? Crowds, prices and the demand peak
September falls inside Florida’s wet season and inside hurricane season, whose statistical peak lands around September 10, and fall discounts across the state exist for exactly that reason, as our season guide explains. We found no occupancy series and no monthly room rates for the counties around the springs, so we crown no month expensive and no month cheap. The 3,000-visitors-a-day figure Florida DEP publishes is a peak-summer-month number, and we could not verify a September count to set beside it.
Arrival time does more work here than booking. The constraint is 909 parking spaces, and the gate closes when they are gone, which is a harder limit than any reservation queue. We could not read the park’s entrance fee or its opening hour, because the state parks site refused our automated checks on September 11, 2026, so call before you set an alarm. A bed within an easy morning drive is the thing worth reserving a few weeks out, the same logic our where-to-stay guide applies statewide.
On tax we have nothing to sell you: we could not verify a lodging-tax rate for the counties nearest the springs, so we give no percentage. A Florida hotel bill generally carries the state sales tax plus a county tourist-development levy, and the county rate is the part that moves. Budget with our Florida cost page and read the final line of your reservation rather than trusting a rate quoted for another corner of the state.
The one spend that changes this month is a night close to the park instead of a dawn departure from Orlando or Jacksonville, because it buys the early arrival that a 909-space lot rewards. Rented tubes are the other place money moves, and we could not verify a current rental price, so ask when you call. Driving in from either coast, budget the car itself: tolls and rentals are their own Florida line item.
Things to do in Ichetucknee Springs in September
September gives you August’s water with roughly three quarters of August’s rain: 5.82 inches instead of 8.10, spread over 7.6 wet days instead of 11.5. Afternoons still run 88.0°F, so the river does the job it does in July, and a 2.8-mile paddling trail becomes a realistic afternoon rather than a gamble on the radar. That combination belongs to this month alone, since October takes the heat away with the rain.
The state’s 2024 facilities inventory counts what is on the ground: 4 canoe, kayak and tube launches, 2.8 miles of paddling trail, 4.2 miles of hiking trail, 1,472 feet of boardwalk and 2 designated swimming areas. Florida DEP’s Visit a Spring page describes three separate canoe and tube launches and more than seven miles of swiftly flowing river, so the two state counts of launches differ by one. We report both rather than pick a winner.
Nothing on that list changes with the calendar except the air around it. The boardwalk that is a shaded stroll in October becomes heat management in September, when afternoons run 5.8 degrees warmer at 88.0°F against 82.2°F. The two swimming areas are where the month disappears altogether: the water you step into in September is the water you would step into in February, and only the walk back to the car tells you which one it is.
We could not read a fee schedule, so we make no claim about free entry or free days this month. What we can name is the legal class Florida keeps for its best springs: statute 373.802(5) defines Outstanding Florida Springs as every historic first-magnitude spring identified by the Florida Geological Survey, plus six named individually in the law. Florida DEP separately names this park among the finest of its spring parks for canoeing, kayaking and tubing, on its own Visit a Spring page.
Ichetucknee Springs in September: a two-day itinerary
Day one belongs to the water, and it starts earlier than anyone wants on vacation. Sunrise on September 15 is 7:14 a.m., so leaving at first light puts you at the gate while the 909 spaces are still open. Float or paddle through the morning as the air climbs toward 88.0°F, eat at midday in shade, then leave the 1 p.m. to 5 p.m. block loose for the wet season’s usual afternoon build. Sunset at 7:37 p.m. gives a long, soft evening for the drive out.
Day two is the walking day: 4.2 miles of trail and 1,472 feet of boardwalk before the heat arrives, then the swimming areas when the air is at its worst. If the sky turns, a wet afternoon in north Florida becomes a driving afternoon, and our road-trip guide has the routes north and west. With 7.6 wet days in the month, about one visit in four meets rain of 0.10 inch or more, and most of it holds off until the morning is spent.
Ichetucknee Springs in September vs August and October
| Measure | August | September | October |
|---|---|---|---|
| Average high | 89.9°F | 88.0°F | 82.2°F |
| Average low | 72.9°F | 69.8°F | 59.9°F |
| Rainfall | 8.10 in | 5.82 in | 2.23 in |
| Days with 0.10 in or more | 11.5 | 7.6 | 3.7 |
| Spring water | No seasonal swing | No seasonal swing | No seasonal swing |
Side by side, September is the middle of a steep fall. August runs 89.9°F by day and 72.9°F at night, with 8.10 inches of rain across 11.5 wet days. September comes in at 88.0°F and 69.8°F, 5.82 inches, 7.6 wet days. October drops hard to 82.2°F, 59.9°F, 2.23 inches and 3.7 wet days. Daytime warmth falls 5.8 degrees between September and October, the nights fall 9.9, and the spring loses nothing in either direction.
Move four weeks later and you gain the dry: 2.23 inches instead of 5.82, and 3.7 wet days instead of 7.6. You give up some of the reason to be in the water, since a 59.9°F October dawn turns a wet swimsuit into a real decision, and daylight shortens at both ends. Move four weeks earlier and August hands back 8.10 inches of rain, 11.5 wet days and the peak-summer traffic the state puts at up to 3,000 visitors a day. September sits between them on every number we can measure.
Is September a good time to visit Ichetucknee Springs?
Yes for anyone whose trip is built around the water, which covers most people who drive here: 88.0°F afternoons make a spring the best idea in the state, and 7.6 wet days leave three visits in four dry at the station. No for travelers who came to hike, since 4.2 miles of trail in 88-degree air with September humidity is a morning rather than a day. And no for anyone booking a non-refundable week, because hurricane season peaks around September 10.
If the answer is no, move to October rather than August: 2.23 inches of rain against 5.82, 3.7 wet days against 7.6, and 82.2°F afternoons that turn the trail into a full day. The cost is the morning swim. At a 59.9°F average low, October dawns ask more of a swimmer than September dawns do, even though the spring itself has not shifted a degree between the two.
No other month pairs August’s water with 2.28 fewer inches of rain and four fewer wet days while the river runs exactly as it ran in August.
The last word
Pick the day rather than the month. With 7.6 wet days out of thirty, three mornings in four come up dry at Cross City, and the rain that does fall usually waits until after lunch. One number we have kept back explains the color of the water: the USGS gauge at Ichetucknee Springs read 23 cubic feet per second leaving the vent on September 11, 2026, a single instantaneous reading rather than a monthly mean. Water replaced that fast has no time to cloud. Call the park for its fee and its hours before you set the alarm, because we could not read either.
