SILVER SPRINGS · SEPTEMBER · CENTRAL FLORIDA
Book Silver Springs for September and you are booking the air, because the vent underneath keeps no calendar. NOAA’s 1991-2020 normals give the month an average high of 89.7°F, an average low of 73.1°F and 5.21 inches of rain. The spring itself was still pushing water at 264 cubic feet per second when the USGS gauge on the run was read in September 2026, the same volume it moves in February.
Compared with August, September drops 1.42 inches of rain and 2.3 wet days while giving up only 2.0°F of afternoon heat. Set against October, it carries 2.59 inches more rain and 4.1 more wet days. The year-round practicalities of the park sit on the main Silver Springs page, and the statewide timing question belongs to the Florida calendar.
THE MONTH AT A GLANCE · SILVER SPRINGS · SEPTEMBER
September hands Silver Springs 89.7°F afternoons and 5.21 inches of rain over roughly eight wet days, above a spring that runs the same all year: start at seven, book a cabin, treat two o’clock as the roof hour.
AVG HIGH 89.7°F · AVG LOW 73.1°F · 8.1 WET DAYS · 12H 22M OF LIGHT ON SEP 15
Go for: warm-air paddling on 6.3 miles of marked trail, 4,775 feet of boardwalk before ten, and light that holds until 7:34 p.m.
Think twice before: planning a swim day, since the state inventory records no designated swimming area, or arriving midmorning on a Saturday, since the gate closes once the 1,686 spaces fill.

One gate decides more September Saturdays than the forecast does: the state counts 1,686 parking spaces at Silver Springs State Park, and when they fill, the entrance closes. Nothing you book online beats a full lot, so the hour you set the alarm for matters more than the day of the week you pick.
Silver Springs weather in September: average highs, lows and rain days

| Average high | 89.7°F |
| Average low | 73.1°F |
| Rainfall | 5.21 in |
| Days with 0.10 in or more | 8.1 |
| Days with 1.00 in or more | 1.2 |

The NOAA NCEI monthly normals for 1991-2020 give September an average high of 89.7°F, an average low of 73.1°F and 5.21 inches of rain. Those come from a real thermometer rather than a model grid cell: station USW00012819 at Leesburg Municipal Airport, about 27 miles (44 km) from the vent. Every figure here is air temperature measured at that airport. It describes the weather you walk through, and says nothing at all about the water in the run.
Rain falls on about 8.1 days of an average September, counting only days that record at least a tenth of an inch. That is measurable rain roughly one day in four, and Florida’s wet season stacks most of it into the afternoon. Of those wet days, 1.2 on average deliver an inch or more, enough to close down outdoor plans for an hour or two. Walk in the first half of the day and keep a roof, a drive or a car within reach from two o’clock on.
Between afternoon and dawn the normals swing 16.6°F, from 89.7 down to 73.1. That is a narrow spread, and it means a September evening stays shorts weather all the way to bed. Pack for wet and warm instead of warm and cold: a rain shell that breathes, a quick-dry shirt for each day, closed shoes for 4,775 feet of boardwalk, and a dry bag if you paddle. Leave the fleece at home.
September 15 delivers 12 hours 22 minutes of daylight, sunrise at 7:12 a.m. and sunset at 7:34 p.m. local time. The front end is the useful end: from 7:12 until about eleven the air sits well under the day’s high and the low light lets you see straight down into the run. Once the sun goes at 7:34, the shaded stretches go dark fast, so start the last loop well before seven.
How warm is Silver Springs in September?
The month’s average high is 89.7°F and its average low 73.1°F, with 16.6 degrees of daily range between them. August runs hotter at both ends, 91.7 and 75.0. We could not verify a water temperature for the spring, so we give no figure for it. And when you see a water temperature quoted for a Florida spot, check what it averages: those tables usually report a mean of daily maxima, which reads a touch warmer than a true 24-hour average.
In practice, a seven o’clock start is genuinely pleasant at around 73°F, and a long-sleeve sun layer does more work on an open boardwalk than sunscreen. By two you are in the high 80s with September humidity on top, and shade becomes the thing you plan around. Carry more water than looks reasonable, wear a hat, and accept that the middle of the day here is for sitting still.
Freezing nights are not a September question at this latitude. The normals we read carry no freeze-day count for the month, and an average low of 73.1°F sits 41 degrees above freezing. The first cool mornings belong to October and November, and October’s average low of 66.1°F is the first real step down the year takes.
How busy is Silver Springs in September? Crowds, parking and prices
September lands at the tail of the wet season and inside the school year, and the park’s own capacity is the clearest demand signal we can verify: 1,686 parking spaces, with the gate closing when they fill. That is a Saturday problem far more than a Tuesday one, and it arrives around midmorning rather than at opening. We found no occupancy series and no monthly room-rate data for the area around the park, so we crown no month cheap and no month expensive.
The scarce bed is countable. The state inventory records 10 cabins inside the park, and ten of anything does not sit empty on a Friday in a warm month. Book that the moment your dates are firm and keep everything else flexible. We could not verify cabin rates or a booking window, so check availability directly rather than trusting a seasonal rule of thumb. The wider Florida bed picture is in our where-to-stay guide.
We could not verify a tourist development tax rate for this county, so we give no percentage. Anything published as a flat “Florida bed tax” is a county-by-county figure, and this one we did not read. Budget the lodging line with the tax unknown and confirm it at the booking screen, where the total is spelled out in full. Our trip-cost guide handles the statewide budget picture.
The one purchase that changes a September here is a roof over the afternoon. With 8.1 wet days in the month and 1.2 of them bringing an inch or more, a cabin or a room nearby turns a washed-out two o’clock into a rest and a second walk at five. A tent turns it into a long wait. We could not price either option, so compare them on the park’s own reservation system.
Things to do in Silver Springs in September: the boardwalk, the paddling trail and the cabins
What September gives that August does not is the same summer warmth with less water falling on it: 5.21 inches against 6.63, and 8.1 wet days against 10.4, for afternoons only 2.0°F cooler at 89.7°F. What October gives instead is dryness at the price of the long evening. Mid-September still has light at 7:30 p.m., so a paddle that starts at four is a comfortable plan rather than a race against the dark.
Florida’s 2024 state facilities inventory counts what is actually on the ground: 4,775 feet of boardwalk, 6.3 miles of paddling trail, 10 cabins and those 1,686 parking spaces. It also records no designated swimming area at Silver Springs State Park, so plan the day dry. The same inventory is inconsistent about launches, with one line returning none and another counting three canoe, kayak and tube launches. We could not reconcile the two readings, so call the park before you drive up with a boat on the roof.
The run has no season. The USGS gauge on the vent read 264 cubic feet per second in September 2026, and at that rate the water is replaced faster than it can cloud, in September as in March. The air is the variable: 89.7°F afternoons make the shaded half of the boardwalk the half worth walking, and they turn 6.3 miles of paddling trail into a morning job rather than a midday one.
We could not verify an entrance fee or an opening hour, so we quote neither, and any price you find on an aggregator deserves a check against the park before you drive. The legal frame we can state: Florida Statutes 373.802(5) protects the state’s Outstanding Florida Springs, meaning every historic first-magnitude spring the Florida Geological Survey identifies, plus six more named by hand in the law. On manatees we also came up short, with no count we could verify; our manatee guide covers the documented winter gatherings.
Silver Springs in September: a two-day itinerary
Day one runs on the front half of the light. Sunrise is 7:12 a.m. in mid-September, so a 7:30 arrival puts you in a lot that still has most of its 1,686 spaces and on the boardwalk while the air holds near 73°F. Give the 4,775 feet of boardwalk until about ten, then take the water: pick a turnaround on the 6.3-mile paddling trail rather than the full run if you started late. Be under a roof by two, then out again at five, with light until 7:34.
Day two flips the order when the sky allows. On a clear morning, take the far end of the trail early and save the hot hours for the drive you were going to make anyway, with our getting-around guide for Florida drive times. If the inch-or-more day arrives, and one falls in an average September, move indoors before the first band, then watch for the gap that usually opens behind a Florida storm and walk the boardwalk at five instead. Families can pair it with the kids guide.
Silver Springs in September vs August and October
| Measure (1991-2020) | August | September | October |
|---|---|---|---|
| Average high | 91.7°F | 89.7°F | 84.5°F |
| Average low | 75.0°F | 73.1°F | 66.1°F |
| Rainfall | 6.63 in | 5.21 in | 2.62 in |
| Days with 0.10 in or more | 10.4 | 8.1 | 4.0 |
Set side by side, September sits 2.0°F under August by day and 5.2°F over October. The bigger gap is at night: 73.1°F here against August’s 75.0 and October’s 66.1, a seven-degree fall in four weeks. Rain moves the same way, from 6.63 inches and 10.4 wet days in August to 5.21 and 8.1 in September, then down to 2.62 and 4.0 in October. No verified water temperature exists on our side for any of the three, so this comparison covers air only.
Shift four weeks later and you trade humidity for dryness: October halves the rain and cuts the wet days to four, and a 66.1°F morning changes what you wear before nine. You lose the warm evenings and part of the daylight. Shift four weeks earlier into August and you take the year’s fullest warmth with 10.4 wet days to schedule around, plus the summer pressure on that lot. Our August page runs those numbers in full.
Is September a good time to visit Silver Springs?
Yes for paddlers, boardwalk walkers and anyone who wants August warmth with two fewer wet days and an inch and a half less rain. No for two groups: anyone who came to swim, because the state inventory records no designated swimming area at the park, and anyone whose day collapses when the afternoon opens up, because 8.1 days of the month carry measurable rain and 1.2 of them carry an inch or more.
If the answer is no, move to October. At 2.62 inches of rain across four wet days, with 84.5°F afternoons and 66.1°F mornings, it is the most predictable of the three months by a wide margin. You give up the warm early hours and the late light in exchange, and you get a calendar you can plan around instead of a radar you check at noon.
What September alone offers is an 89.7°F afternoon standing over a spring that was pushing 264 cubic feet per second when the gauge was last read, at a point in the year when rainfall has already dropped a fifth below August’s.
The last word
Book the cabin first: ten of them exist, and in a month with 8.1 wet days a roof at two o’clock is the purchase that saves the trip. Then choose your hours rather than your dates, because a 7:30 a.m. arrival buys 73°F air, a share of 1,686 spaces that has not yet gone, and the park’s five observation platforms to yourself before the heat lands. Confirm the entrance fee and the opening hour with the park when you book, since we could not read them ourselves. Then start walking while the light is still low over the run.
