TROY SPRING · MARCH · THE MONTH GUIDE
The water at Troy Spring was reading 71.4°F (21.9°C) the last time the USGS gauge was checked, and it reads close to that in July, in December and on whatever March morning you turn up. What changes in March is everything above the surface: afternoons averaging 74.9°F, dawns averaging 49.6°F, and a bowl of clear water that looks a great deal friendlier at two o’clock than at eight.
March asks for a little patience in return. It is the wettest of the three months around it, 3.53 inches against February’s 2.96 and April’s 2.90, and an average March still drops two nights to freezing. Pack for both ends of the day, aim the swim at the warm end, and you get a north Florida spring in the season when most of the state is looking at the coast instead.
THE MONTH AT A GLANCE · TROY SPRING · MARCH
March is the month the air and the spring very nearly agree, 74.9°F against 71.4°F, and a 25-space lot decides the rest of your plan.
AVG HIGH 74.9°F · AVG LOW 49.6°F · SPRING 71.4°F · 25 PARKING SPACES
Go for: a 71.4°F swim under 74.9°F afternoons, twelve hours of daylight, and a park you can walk end to end in half a day.
Think twice before: planning a dawn start, with 49.6°F mornings and two freezing nights in an average March, or rolling in after lunch when the 25 spaces are gone.

Every air figure here comes from one real thermometer, and it is not standing at the spring: NOAA’s 1991-2020 monthly normals for station USW00012833, Cross City AP, about 27 miles (44 km) away. Over that thirty-year period March averages a high of 74.9°F, a low of 49.6°F and 3.53 inches of rain. Those numbers describe the air over a stretch of north Florida. The water in the spring answers to the aquifer, not to the calendar, and it ignores all of them.
Rain comes in fewer, fatter installments than the monthly total suggests. An average March records measurable rain, 0.10 inch or more, on 4.6 days, roughly one day in seven, and posts an inch or more on 0.6 day, so a real soaking lands in about three Marches out of five. In practice that reads as a gray morning and a band of rain that moves through by afternoon. Two nights in the area almost always leave one dry swimming window.
The gap between a 74.9°F afternoon and a 49.6°F dawn runs 25.3°F. Most visitors pack for one end of it and shiver through the other. A fleece or hoodie you can peel off, swimwear underneath, two towels rather than one, and shoes you do not mind walking back to the car wet will cover a March day here. Sunscreen still applies at 74.9°F, and the water gives back a good deal of what the sky sends down.
Light is generous by mid-month. On March 15 the sun rises at 7:39 a.m. and sets at 7:41 p.m. local time, 12 hours and 2 minutes apart, with the clocks already moved forward. That pushes the usable end of the day past seven, so an afternoon swim no longer means driving home in the dark. The first two hours after sunrise remain the coldest of the twenty-four, whatever the afternoon does later.
How cold is the water at Troy Spring in March?
71.4°F is the figure to plan around. The USGS gauge at the spring, station 02320250, read 71.4°F (21.9°C) on September 11, 2026, and a spring of this class holds close to that all year. That is one instantaneous reading rather than a monthly mean of daily maxima, and we have no March series to set beside it, so treat it as the spring’s steady state. Against a 74.9°F afternoon the water sits 3.5°F cooler. Against a 49.6°F dawn it runs 21.8°F warmer.
Dressing for it is a two-act business. At nine in the morning the air is still climbing out of the fifties and the water is the warmest thing in the park, which is exactly when nobody wants to get in. By one or two o’clock the air has reached its 74.9°F average and the first step off the platform draws a gasp from most people. Swim in the middle of the day, keep a dry layer within arm’s reach for the climb out, and March behaves.
Frost is part of the month. Two nights in an average March fall to 32°F or below at the Cross City station, so a windshield scraper is not an absurd thing to have in a Florida trunk in early March. The spring itself notices nothing. On those mornings the run steams, the contrast is at its most theatrical, and the swim is still 71.4°F whenever you are brave enough.
How busy is Troy Spring in March, and what does a visit cost?
We found no occupancy series and no monthly room-rate data for this stretch of north Florida, so we crown no month cheap and no month expensive. What we can count is the ground: Florida’s own recreational facilities inventory lists 25 parking spaces at Troy Spring State Park. Twenty-five is the whole capacity of the place in any month, and when the lot fills, the gate closes. That ceiling, not the season, is what sets the tone of a clear Saturday.
So the planning decision is an hour, not a booking window. Be parked in the morning on a bright weekend and the day unfolds at your pace; arrive after lunch and you are gambling on someone else leaving. Weekdays in March are a different park altogether. If you do find the gate shut, the rest of the region still has a day in it, and our Florida things-to-do guide names the alternatives within a reasonable drive.
On money we owe you two admissions. We could not verify an entrance fee or a posted opening hour for Troy Spring: the state parks site returns a 403 to automated reads, so we quote neither. We could not verify a county lodging-tax rate either, so we give no percentage. Check the park’s own page in the week you drive, and our Florida trip-cost guide covers how the nightly layers usually stack elsewhere in the state.
One purchase changes March here more than any other: something to wear in 71.4°F water. A rashguard, or a shorty if you own one, turns a three-minute gasp into a half-hour float, and in a month whose afternoons average 74.9°F you feel the chill more on the way out than on the way in. The second worthwhile spend is a second night nearby, which absorbs one of the 4.6 wet days without costing you the swim.
Things to do at Troy Spring in March
March offers a balance the neighboring months do not. Air and water sit 3.5°F apart, closer than at any point in this three-month stretch. In February the average afternoon runs 1.8°F cooler than the spring, so getting out of the water is a downgrade. By April the air averages 80.1°F, 8.7°F above the water, and the spring starts to feel sharp by contrast. March is the month you can swim, dry off and keep wearing the same shirt.
The state’s inventory counts everything the park holds, and the list is short: 1 designated swimming area, 1 launch for canoes, kayaks and tubes, 0.4 mile of paddling trail, 0.3 mile of hiking trail, 50 feet of boardwalk and those 25 parking spaces. Florida law puts the spring in select company, protecting it under Florida Statutes 373.802(5) as an Outstanding Florida Spring. All of it fits in half a day, and 25 cars fill the place.
What March moves is the walking, not the swimming. The 0.3-mile trail and the 50 feet of boardwalk are pleasant at 74.9°F and sticky by midsummer, and the 0.4-mile paddling trail fits into twelve hours of daylight with room to spare. The spring at the end of all three holds its 71.4°F either way. Seasons happen to the air above this park; the water underneath simply keeps arriving.
We cannot tell you what is free. No entrance fee appears in any source we could read, and we will not repeat a figure borrowed from another Florida park, because fees differ park by park and season by season. We also found no manatee count for this spring, so we promise no animals; the winter gatherings that do happen elsewhere in Florida get their own treatment in our manatee guide.
Troy Spring in March: a two-day itinerary
Day one runs backward from the heat. Sunrise on March 15 is 7:39 a.m., but leave the early hours to the drive: be at the gate around nine thirty while spaces remain, then take the 0.3-mile trail and the boardwalk first, in air still in the fifties. Late morning, put the kayak or tube on the 0.4-mile paddling trail. Save the swim for one to three o’clock, when the air reaches its 74.9°F average, and use the light until 7:41 p.m.
Day two reverses it: paddle early while the park is quiet, then swim again after lunch, since 71.4°F is 71.4°F on a second visit. If one of the month’s 4.6 wet days lands on you, the rain is usually a single band rather than a whole day, and the water is unaffected by what falls on it. Wait it out with a long lunch and the road, then come back at three. Our getting-around guide has the driving side.
Troy Spring in March vs February and April
| February | March | April | |
|---|---|---|---|
| Average high | 69.6°F | 74.9°F | 80.1°F |
| Average low | 45.2°F | 49.6°F | 55.0°F |
| Precipitation | 2.96 in | 3.53 in | 2.90 in |
| Days with 0.10 in or more | 4.8 | 4.6 | 4.1 |
| Spring water | 71.4°F | 71.4°F | 71.4°F |
The three months move the air and leave the water alone. March runs 5.3°F warmer by day than February and 5.2°F cooler than April, with nights climbing 4.4°F from February and another 5.4°F into April. Rain is the odd one out: March records slightly fewer wet days than February, 4.6 against 4.8, yet drops 0.57 inch more water, so the rain that does fall in March falls harder. April is the driest of the three at 2.90 inches.
Shift four weeks later and you gain warmer afternoons, drier skies and a real chance that the spring feels bracing rather than neutral. You lose the balance: at 80.1°F the air is 8.7°F above the water, and the park that fits 25 cars gets busier as Florida warms up. Shift four weeks earlier and February gives you quieter mornings and afternoons that average 1.8°F cooler than the spring itself, which is a colder bargain than it sounds.
Is March a good time to visit Troy Spring?
For swimmers and paddlers, yes, and firmly. March gives you the closest agreement of the year between the air and a spring that never changes, 74.9°F against 71.4°F, twelve hours of daylight by mid-month, and a park small enough to know by lunchtime. For anyone hoping to start at dawn, it is the wrong month: 49.6°F averages and two freezing nights make the first hours miserable and the water untouchable until the sun has done some work.
If that describes you, take April instead. Afternoons average 80.1°F, mornings hold at 55.0°F, and rain drops to 2.90 inches across 4.1 days, the driest and mildest of these three months by every measure we have. The trade is company: warmer weekends put more cars on a lot with 25 spaces, and the gate closes when it closes, so an April visit starts earlier than a March one.
No other month puts a 71.4°F swim and a 74.9°F afternoon within 3.5°F of each other, and that narrow gap is the whole case for coming in March.
The last word
Decide the hour, not the week. Nothing here can be reserved as far as we could verify, the swim is the same temperature every day of the year, and the only thing that can genuinely ruin the trip is arriving to find all 25 spaces taken. It helps to know what you are driving toward: the statute that protects this water covers every historic first-magnitude spring in Florida, plus six more named by hand in the law. Throw a fleece and two towels in the car, and be parked by ten.
