SILVER GLEN SPRINGS · MARCH · FLORIDA
March here is a story about two temperatures that ignore each other. The air over this corner of north central Florida averages a high of 75.8°F for the month and a low of 49.7°F. The spring water has no season at all: it leaves the vent at the same temperature in March as it does in July, and that mismatch is the whole reason a March weekend at a Florida spring works.
What the month hands you: 12 hours and 2 minutes of daylight on the 15th, afternoons in the mid-70s, and no heat index worth discussing. What it charges: 3.49 inches of rain, the wettest of February, March and April, measurable rain about one day in six, and spring-break traffic on every road in the state. For the spring itself rather than the calendar, our Silver Glen Springs guide covers it year round.
THE MONTH AT A GLANCE · SILVER GLEN SPRINGS
March buys you mid-70s afternoons, twelve hours of light and water that never changes temperature, at the price of the wettest month of the spring shoulder and a genuinely cold hour before breakfast.
AVERAGE HIGH 75.8°F · LOW 49.7°F · 3.49 INCHES · 5.3 WET DAYS · 12H 02M OF DAYLIGHT
Go for: swimming in water that has no season, long dry afternoons in the mid-70s, and a day that runs from 7:34 a.m. to 7:36 p.m.
Think twice before: planning a dawn arrival in shorts: an average March still drops 1.2 nights to 32°F or below, and we could not verify the opening hour.

For most visitors this is a day trip built around a drive, and for the rest a two-night weekend with the spring as its anchor. If your dates land on a weekend, book the bed before the rest of the plan firms up, because March is spring-break season across Florida. Our Florida getting-around guide handles cars, tolls and rental quirks, and the statewide season view explains why November through April is the dry half of the year.
Silver Glen Springs weather in March: average highs, lows and rain days
| March normal (1991-2020) | Figure |
|---|---|
| Average high | 75.8°F |
| Average low | 49.7°F |
| Day-to-night gap | 26.1°F |
| Precipitation | 3.49 in |
| Days with 0.10 in or more | 5.3 |
| Days with 1 in or more | 1.0 |
| Nights at 32°F or below | 1.2 |
| Daylight on March 15 | 12h 02m |
The figures come from NOAA’s National Centers for Environmental Information, 1991-2020 monthly normals, station USW00012816 at Gainesville Regional Airport, roughly 48 miles from the vent. That provenance matters: these are station normals off a real thermometer rather than a reanalysis grid cell, and every figure here describes the air, not the water. March averages a high of 75.8°F, a low of 49.7°F and 3.49 inches of precipitation.
Rain reaches 0.10 inch or more on 5.3 days in an average March, and one of those days brings an inch or more. Call it measurable rain about one day in six, plus a single proper soaking. At a spring, the arithmetic is kinder than it looks, since you were going to be wet anyway. What a wet day really costs is the picnic and the drive home. The other 26 days stay dry.
The distance between that high and that low is 26.1°F, and it lands inside a single day. A 7:30 a.m. arrival is a fleece-and-long-pants proposition, while 2 p.m. is shorts. Pack both, plus a second towel, because 49.7°F air and a wet swimsuit make a miserable pairing. A windbreaker for the drive home after sunset is worth the space it takes.
On March 15 the sun rises at 7:34 a.m. and sets at 7:36 p.m. local daylight time, leaving 12 hours and 2 minutes between them. That near-perfect split puts the last comfortable swim somewhere around 4 p.m., while the air still holds the 70s and before it starts falling toward the night’s 49.7°F. Out of the water by 5 and out of the parking lot by 6 keeps the entire drive home in daylight.
How warm is Silver Glen Springs in March?
The month’s two poles are 75.8°F and 49.7°F, a spread of 26.1 degrees. That is the widest daily swing of the three spring months: February runs 70.9 and 45.9 for a 25.0-degree gap, April 81.5 and 55.5 for 26.0. March asks you to dress for two different days between breakfast and lunch.
In practice, the morning wants long sleeves and closed shoes, and the coffee stays hot for a reason. By early afternoon the air sits in the mid-70s and the swimsuit finally makes sense, which is when the water stops feeling like a dare and starts feeling like the point of the trip. Anything you want dry by 5 p.m. should be hanging in sunlight by 1.
Frost is not a rumor in this part of Florida: an average March records 1.2 nights at 32°F or below at the Gainesville station. Those are pre-dawn readings, gone by mid-morning, but they decide what you sleep in and what you scrape off the windshield. As for the water, we could not verify a temperature reading for the spring itself, so we give no figure. What is documented is that its output does not follow the calendar.
How busy is Silver Glen Springs in March? Crowds, prices and booking ahead
March sits in the back half of Florida’s dry season, November through April, and it doubles as spring-break month across the state. Both of those are calendar facts, not rates. We found no occupancy series and no monthly room-rate data, so we name no cheapest month and no most expensive one. What can be said plainly is that Florida’s busiest weeks and its best weather share the same squares on the calendar.
With fixed weekend dates, book the bed four to six weeks out (est.) rather than the week before, and treat arrival time as the variable you actually control. Get there early. We could not verify the lot’s capacity or its opening hour, and a spring-break Saturday is a poor day to test either one. Our Florida trip cost guide covers the lines that move most between seasons.
We could not verify a county lodging-tax rate for this area, so we quote no percentage. The same gap applies to admission: floridastateparks.org returned a 403 to our automated reads, so we carry no entrance fee and no gate time. Call the managing office before you build a morning around an opening hour, and see our know-before-you-go guide for the statewide park rules we could confirm.
The one line worth paying up for in March is distance. A bed near the forest instead of a cheaper one an hour out buys the early arrival, and in a month carrying 5.3 wet days it also buys the freedom to swap Saturday for Sunday when the rain lands badly. Nothing else in the budget changes what the month feels like.
Things to do in Silver Glen Springs in March
March lets you stay outdoors all day without negotiating with the weather. February mornings start at 45.9°F and April afternoons push to 81.5°F; March splits the difference at 75.8°F, with 12 hours and 2 minutes of light on the 15th to spend however you like. Paddling, walking the run, eating outside and swimming all fit into one daylight stretch without anyone hiding from the sun or from the cold.
The vent is the attraction. A USGS gauge, station 02236160, logged 87 cubic feet per second leaving it on September 11, 2026, an instantaneous reading rather than a monthly mean. That volume is why the water is clear: it gets replaced faster than it can cloud. Florida law has a name for water of this class, Outstanding Florida Springs. On manatees we have nothing solid, since the FWC pages render client-side and we could not read a count; our manatee guide has the statewide picture.
What March changes is the contrast, not the water. The spring runs the same in March as in July while the air around it moves 26.1 degrees between dawn and mid-afternoon. Swim at 9 a.m. and the water feels warm against cool air. Swim at 3 p.m. and the same water feels like a plunge. Same spring, same day, two entirely different swims, and that gap is the only thing the season controls.
Free is the part we could not pin down. No fee schedule we could read, no confirmed hours, so we list no price, no discount and no free day for March. What costs nothing regardless: the walk along the run before the parking lot wakes up, and the first hour of light at 7:34 a.m., which in March arrives at a civilized time rather than a heroic one.
Silver Glen Springs in March: a two-day itinerary
Day one runs on the light. Aim to be at the spring not long after the 7:34 a.m. sunrise, in the fleece, and walk first while the air is still in the 50s. Save the swimming for late morning, once the thermometer has climbed most of its 26.1 degrees. Eat outside in the early afternoon, the warmest stretch of a 75.8°F day. Be out of the water by 5 p.m. and on the road by 6, ahead of the 7:36 p.m. sunset and the drop that comes after it.
Day two is the flexible one, and 5.3 wet days a month is the reason to keep it that way. If the rain is the inch-or-more kind, and that day comes once in an average March, trade water for road miles: St. Augustine’s old town works with a roof overhead, and our things to do in Florida page has the rest of the wet-day options. If it is the passing kind, stay put. You are already wet, and rain changes nothing about the water you are standing in.
Silver Glen Springs in March vs February and April
| Measure | February | March | April |
|---|---|---|---|
| Average high | 70.9°F | 75.8°F | 81.5°F |
| Average low | 45.9°F | 49.7°F | 55.5°F |
| Precipitation | 2.67 in | 3.49 in | 2.74 in |
| Days with 0.10 in or more | 4.1 | 5.3 | 3.8 |
| Spring water | No seasonal change | No seasonal change | No seasonal change |
Across the three months the air climbs on a straight line: 70.9°F and 45.9°F in February, 75.8 and 49.7 in March, 81.5 and 55.5 in April. Rain refuses to follow that line. March is the wettest of the three at 3.49 inches against February’s 2.67 and April’s 2.74, and it carries 5.3 days of measurable rain against 4.1 and 3.8. The water in the run is the constant in all three columns, so the air is the only variable worth comparing.
Move four weeks later and you gain 5.7 degrees of afternoon, 5.8 degrees off the cold end of the night, three-quarters of an inch less rain and 1.5 fewer wet days. You give up the cool morning, if the cool morning was part of the appeal. Move four weeks earlier and February hands you a drier month, 0.82 inches drier, with afternoons topping out at 70.9°F and mornings near 45.9°F; our February page has that month in full.
Is March a good time to visit Silver Glen Springs?
Yes for anyone who wants a full day outdoors without the heat, and yes for swimmers who do not mind starting the morning in a fleece. No for a trip that depends on one specific dry Saturday, because 5.3 wet days is modest but March is still the wettest of the spring months. And no for a group that needs warm air before it will tolerate cool water, which is an April argument rather than a March one.
April is the swap if the answer is no. It runs 5.7 degrees warmer by day, 0.75 inches drier, and its 3.8 wet days are the fewest of the three months. The cost is the 55.5°F night, which is comfortable rather than crisp, and the loss of the one thing March does better than either neighbor.
That one thing: the widest gap of the three months between a 49.7°F dawn and a 75.8°F afternoon, stretched over water that holds steady through both ends of it.
The last word
Pick the weekend, pack for two climates in one day, and call ahead before you build a morning around a gate time, since we could not verify an opening hour or an entrance fee. Then stop planning. A 75.8°F afternoon, twelve hours of light and water sitting at its July temperature is about as much as a Florida March owes anybody. For the record, the legal term for water of this class is Outstanding Florida Springs, a category Florida Statute 373.802(5) builds from every historic first-magnitude spring, as the Florida Geological Survey determines them, plus six more named by hand in the text.
