FLORIDA · ICHETUCKNEE SPRINGS · AUGUST
August brings the hottest air Ichetucknee gets and the busiest water it sees. At Cross City Airport, the nearest official thermometer and about 27 miles from the springs, the 1991-2020 normal high for the month is 89.9°F (32.2°C), with 8.10 inches of rain falling across 11.5 days. The spring under the cypress ignores all of it. Its water has no season.
That contrast draws a crowd. Florida’s Department of Environmental Protection counts as many as 3,000 visitors a day at Ichetucknee Springs State Park during peak summer months, and the state’s own facilities inventory lists 909 parking spaces. When the lot fills, the gate closes, so an August Saturday is settled before mid-morning. Build the trip around your arrival time, and book nights within easy reach of the entrance.
THE MONTH AT A GLANCE · AUGUST
August pairs the year’s hottest air with a river that never changes, so the trip works as long as you are in the lot early and off the water when the afternoon storm builds.

Go for: a cold river under a hot sky, 4.2 miles of shaded trail, 2.8 miles of paddling, and light on the water until 8:13 p.m. on the 15th.
Think twice before: arriving after mid-morning on a summer weekend, or counting on a published water temperature: we could not verify one, and the park’s fee schedule and opening hour were unreadable to us on September 11, 2026.

Anything that holds true in every season lives in our Ichetucknee Springs guide. For how the month fits a wider trip, the twelve-month Florida verdict ranks the state’s seasons and our cost guide handles the budget. Everything below is dated to August.
Ichetucknee Springs weather in August: average highs, lows and rain days
| August normal | Figure |
|---|---|
| Average high | 89.9°F (32.2°C) |
| Average low | 72.9°F (22.7°C) |
| Monthly rainfall | 8.10 in |
| Days with 0.10 in or more | 11.5 |
| Days with 1 in or more | 2.4 |
| Daylight on August 15 | 13 h 15 min |
Every figure here comes from one instrument: NOAA’s National Centers for Environmental Information, 1991-2020 monthly normals, station USW00012833 at Cross City Airport, roughly 44 km (27 miles) from the springs. These are station normals from a real thermometer, not a gridded reanalysis of a model cell, and the difference between the two is worth knowing when you read a weather figure anywhere. They also describe air. The spring is not in them.
Measurable rain falls on 11.5 days in an average August, roughly one day in three, and 2.4 of those days deliver an inch or more. It rarely reads as gray drizzle. Heat builds over the peninsula through the day and comes down hard and short in the afternoon, so a float launched at nine usually finishes before anything happens. Watch the sky from noon onward, and treat the first thunder as the end of the water day rather than a warning.
Seventeen degrees separate that high from that low, which is a narrow swing by continental standards and still enough to matter at seven in the morning. Pack for wet, not for cold: quick-dry clothes, shoes that survive limestone and roots, a dry bag for phone and keys, a light rain shell. No fleece earns its space in an August car. Sunscreen counts for more on the open stretches of river than under the canopy, where the shade is close to total.
On August 15 the sun rises at 6:57 a.m. and sets at 8:13 p.m. local time, about 13 hours 15 minutes of daylight. The evening half of that is the useful half. Heat peaks through mid-afternoon, then the last two hours before sunset give you cool air with the sun still up, so the walk or the second float belongs at six rather than at noon.
How warm is Ichetucknee Springs in August?
The month runs a normal high of 89.9°F (32.2°C) and a normal low of 72.9°F (22.7°C), a spread of 17 degrees. July beats it by two tenths of a degree, September gives back 1.9.
At seven in the morning the air sits near 73°F with humidity to match, and a T-shirt over the swimsuit is the whole outfit. By two in the afternoon the lot is close to 90°F and the two comfortable places are the water and the canopy shade. A hat, then, and a towel that actually dries, because one that doesn’t will still be damp at dinner.
Freezing nights play no part. Our normals carry no count of nights at or below 32°F for August, and the month’s average low sits nearly 41 degrees above it. The only cold you will feel comes from the river, and it lasts exactly as long as you stay in it.
How busy is Ichetucknee Springs in August? Crowds and prices
August falls at the back end of the peak summer stretch that Florida’s Department of Environmental Protection describes as drawing as many as 3,000 visitors a day to the park. We found no occupancy series and no monthly room-rate data for the area, so we crown no month expensive and none cheap. The demand signal that is countable is the lot: 909 spaces against a peak day more than three times that number.
We could not verify whether tubing here takes a reservation, so we name no booking window in weeks. The constraint we can name is parking. Spaces go first come, the gate shuts when they are gone, and the lever that works on an August weekend is an early alarm rather than a click six weeks out. A weekday visit removes most of the pressure, and our where-to-stay guide sorts the regions if you need a base.
We could not verify a local lodging-tax rate, so we give no percentage and no all-in nightly figure. Ask whoever takes your booking for the total with taxes included, then compare that against the room rate you were quoted. The gap is usually where a weekend budget goes wrong.
Spending more changes one thing in August, and that thing is where you sleep. A bed near the entrance turns an early arrival into an ordinary morning instead of a pre-dawn drive, and on a 3,000-visitor Saturday it decides whether you float the river or photograph a closed gate. Getting there is its own question, and our getting-around guide covers the driving.
Things to do in Ichetucknee Springs in August
In midwinter, getting into this water is a dare. In August, with air at 89.9°F and shade doing the rest, the river is simply the sensible place to be, and that is the month’s entire argument. Length of day helps too: 13 hours 15 minutes on the 15th leaves room for a morning float, a long lunch out of the sun, and a second lap before the 8:13 p.m. sunset.
The state’s 2024 facilities inventory counts what the park holds: 4 canoe, kayak and tube launches, 2.8 miles of paddling trail, 4.2 miles of hiking trail and 1,472 feet of boardwalk. The same agency’s Visit a Spring page describes three separate canoe and tube launches and more than seven miles of swiftly flowing river, so two state documents disagree on the launch count and we give you both. USGS gauge 02322685 measured 23 cubic feet per second leaving the vent on September 11, 2026, and that turnover is why the water reads like glass.
Nothing in the river itself moves between February and August. The air moves plenty, 1.9 degrees off September and a great deal more off midwinter, and that gap is what makes the same 2.8-mile paddle a different outing in August. Florida law puts the place in a protected class while it is at it: Statute 373.802(5) defines Outstanding Florida Springs as every historic first-magnitude spring identified by the Florida Geological Survey, plus six more named by hand in the text.
We cannot tell you what is free in August. Our reads of the park’s official fee schedule and opening hour returned a 403 on September 11, 2026, and fees vary by park and by season, so a price quoted for another Florida spring does not transfer to this one. Call the park before you drive, and budget for an entrance fee rather than assuming there is none.
Ichetucknee Springs in August: a two-day itinerary
Day one belongs to the river. Be at the gate at opening, while the air is still nearer the 72.9°F overnight low than the afternoon figure and the 909 spaces are still unspoken for. Float through the morning, eat by one, and hand the hottest stretch, roughly noon to four, to shade or air conditioning. Come back around six for the trail, when the light is long and the heat has broken, and let the 8:13 p.m. sunset time your exit.
Day two trades the current for the bank: the 2.8 miles of paddling trail if you have a boat, then the 4.2 miles of hiking trail and the 1,472 feet of boardwalk, which handle the heat better under cover. If the sky stacks up after lunch, and on 11.5 days a month it does, get off the water before the first thunder. An inch of rain arrives 2.4 times in an average August, and it comes with lightning.
Ichetucknee Springs in August vs July and September
| 1991-2020 normal | July | August | September |
|---|---|---|---|
| Average high | 90.1°F | 89.9°F | 88.0°F |
| Average low | 72.5°F | 72.9°F | 69.8°F |
| Rainfall | 7.77 in | 8.10 in | 5.82 in |
| Days with 0.10 in or more | 11.6 | 11.5 | 7.6 |
| Spring water | not verified | not verified | not verified |
Line the three up and August is the wettest of them, 8.10 inches against July’s 7.77 and September’s 5.82. Daytime heat barely shifts between July and August, 90.1°F down to 89.9°F, then falls to 88.0°F. Nights carry the real change: 72.9°F in August, 69.8°F four weeks later. Wet days track the rain totals at 11.6, 11.5 and 7.6. All of it comes from the same NOAA station over the same 1991-2020 period, so the comparison is like for like. The water, in all three months, stays where it is.
Moving the trip four weeks forward buys 2.28 inches less rain, 3.9 fewer wet days and a night 3.1 degrees cooler. It costs daylight, and it costs the summer crowd, which plenty of readers will count as a second gain. Moving four weeks back buys nothing: July is two tenths hotter, a third of an inch drier and a tenth of a day wetter in count, differences no one standing in the river could feel.
Is August a good time to visit Ichetucknee Springs?
Yes, if the water is the point. A 90-degree afternoon is exactly what makes a constant-temperature spring feel like a miracle, and families with school-holiday weeks to fill have no better use for one in north Florida. No, if your plan is a long hike in open sun, a photography day that needs clear light after lunch, or a schedule with no slack for the storm that arrives on roughly one day in three.
If that is a no, take September instead. Rain drops to 5.82 inches over 7.6 wet days, nights settle to 69.8°F, and the peak summer stretch the state describes is behind you, which means the 909 spaces last later into the morning. You give up about two degrees of the contrast that makes the swim so good, and some evening light.
August alone among the three combines the wettest skies, 8.10 inches, with the warmest nights, 72.9°F, so a seven o’clock launch needs nothing but a swimsuit and the river is still the coldest thing you will touch all day.
The last word
Settle the arrival time first and the rest of the weekend arranges itself: the 909 spaces are gone before the day turns hot, and the state counts only 2 designated swimming areas for a park that can see 3,000 people. Pick your morning, pack the dry bag, and check the entrance fee and the opening hour with the park before you drive, because those are the two things we could not read.
