BLUE SPRING · APRIL · VOLUSIA COUNTY
April is the month the air catches up with the water at Blue Spring. The spring itself runs near 74.3°F whatever the calendar says, while the average afternoon climbs to 83.2°F, up from 78.4°F in March. Nine degrees of difference between air and water is what separates a bracing dip from a swim you stay in.
It is also the last month of Florida’s dry season, and the driest of the three months around it: 2.70 inches of rain spread over 3.9 days. What April cannot promise is a parking space. The state counts 187 of them at the park, and the gate closes when they fill. Statewide season logic sits in our best-time guide.
THE MONTH AT A GLANCE · APRIL
April gives you the warmest air of the dry season over water that never moves off 74.3°F, plus the lowest rainfall of the three spring months: come on a weekday and arrive before the 187-space lot fills.
AVERAGE HIGH 83.2°F · WATER NEAR 74°F YEAR-ROUND · 3.9 RAIN DAYS
Go for: a swim in 74.3°F water under afternoons that average 83.2°F, 3,050 feet of boardwalk, and the driest month of the three around it.
Think twice before: driving out on a warm Saturday afternoon: the park holds 187 cars, and when the lot fills the gate closes.

Blue Spring weather in April: average highs, lows and rain days
| April at Blue Spring | The normal |
|---|---|
| Average high | 83.2°F |
| Average low | 62.8°F |
| Precipitation | 2.70 in |
| Days with 0.10 in or more | 3.9 |
| Days with 1.00 in or more | 0.5 |
| Daylight, April 15 | 12h 56m |
| Sunrise / sunset, April 15 | 6:57 a.m. / 7:53 p.m. |
Every figure here comes from one place: NOAA’s NCEI monthly normals for 1991-2020, station USW00012841, which sits at Orlando Executive Airport about 27 miles from the spring. That thermometer gives 83.2°F for the average April high, 62.8°F for the average low and 2.70 inches of rain for the month. It measures air, and only air. The water at the vent has its own instrument and its own answer.
Of those 2.70 inches, 3.9 days in an average April record at least a tenth of an inch, and half a day records an inch or more. Translated into a visit, that is measurable rain roughly one day in eight, and a genuine soaking in about one April out of two. The other twenty-six days of the month register less than a tenth of an inch between them.
Dawn averages 62.8°F and mid-afternoon averages 83.2°F, so one outfit will be wrong twice in the same day. Sleeves and closed shoes for the first hour on the boardwalk, swimsuit underneath for later, and a towel that is still dry when you get out. A wet swimmer in low-sixties air discovers why April needs a bag.
On April 15 the sun rises at 6:57 a.m. and sets at 7:53 p.m. local time, for 12 hours 56 minutes of daylight, calculated from sunrise-sunset.org. The useful part is the tail end. Light holds past 7:30 p.m., long enough for a slow loop of the boardwalk once the swimming area has emptied out.
How warm is Blue Spring in April? Air highs, night lows and spring water temperature
The month’s two poles are 83.2°F and 62.8°F, 20.4 degrees apart, and the spring sits between them at 74.3°F. That water reading came off the USGS gauge at station 02235500 on September 11, 2026, a single instantaneous measurement rather than a monthly average. It carries further than most spot readings would: the vent replaces its own volume constantly, and the gauge returns close to the same number on any day of the year.
At 7 a.m. in the low sixties you want sleeves for the walk down. By two in the afternoon, with the air averaging 83.2°F, 74.3°F water stops feeling cold inside a minute and the shade under the canopy becomes the contested real estate. Keep one dry layer in the bag for the walk back to the car, because the air slides toward its overnight figure as soon as the sun drops.
We found no count of freezing nights in the NOAA April normals we read, so we give none. With an average low of 62.8°F, a frost this late in the season would sit far outside the average, and even March, cooler by 4.5 degrees at night at 58.3°F, is a long way from it.
How busy is Blue Spring in April? Parking, crowds and entrance fees
We found no occupancy series and no monthly room-rate data for this corner of Volusia County, so we crown no month expensive and none cheap. The calendar fact stands on its own: April closes out Florida’s November-to-April dry season, the stretch the whole state builds its winter reputation on, and it does it with the warmest air of the six.
The booking that genuinely competes is the cabin, because the state counts six of them for the entire park. Six units against a warm April Saturday is a problem of dates, not of season, so ask for the dates you want and be ready to move them. Day visitors book nothing at all. They queue: 187 spaces, first come, gate closed when the last one goes.
We could not verify the Volusia County lodging-tax rate, so we quote no percentage. The same applies to the park’s entrance fee: floridastateparks.org answers automated requests with a 403, and we would rather leave that line blank than transplant a price from another park. Ask at the ranger station or call before you drive out.
One upgrade changes April more than any other, and it is sleeping inside the gate. A cabin puts you on the boardwalk at 6:57 a.m. with no drive attached, and it removes the only real April risk: arriving at noon behind 187 parked cars.
Things to do in Blue Spring in April
May pushes the air to 88.2°F but pays for it with 5.3 days of measurable rain. March holds the afternoon at 78.4°F, a figure that reads cool the moment you climb out of 74.3°F water. April lands in the gap: warm enough to dry off in ten minutes, dry enough to commit a whole day to being outside.
Florida’s own facility inventory counts what the park holds: one designated swimming area, 3,050 feet of boardwalk, three observation platforms, one launch for canoes, kayaks and tubes, six cabins, 187 parking spaces. That is the full menu, and it fills two unhurried days. The boardwalk follows the run above the water, the platforms look straight down into it, and the launch is where paddling starts.
None of those counts move with the season, and neither does the water: the gauge returns close to 74.3°F whatever the month. Air is the variable, running 78.4°F in March, 83.2°F in April, 88.2°F in May, so the same swim feels different at each step. Nine degrees between the afternoon and the spring is what makes April’s version comfortable rather than brisk.
We could not read the park’s entrance fee, so we name no price and claim no free day in April. What we can count is what comes with admission once you are through the gate: 3,050 feet of boardwalk, three platforms and the swimming area, with no second ticket between them. Manatee numbers belong to another season and another agency, and we found no verified April figure.
Blue Spring in April: a two-day itinerary
Day one starts at the gate. Sunrise on April 15 is 6:57 a.m. and the air is near 62.8°F, so the first hour on the 3,050-foot boardwalk is the cool one, with the three observation platforms to yourself. Swim between noon and three, when the average reaches 83.2°F and 74.3°F water stops being a shock. Keep late afternoon for shade, and remember light holds until 7:53 p.m.
Day two goes on the water, using the one launch for a canoe, kayak or tube before the heat peaks. If the sky turns, only 3.9 days in an average April record a tenth of an inch, and a wet hour does nothing to the spring’s temperature. A full soaking day, the kind that turns up in roughly half of all Aprils, is the one to spend elsewhere, and our Florida list holds the indoor options.
Blue Spring in April vs March and May
| March | April | May | |
|---|---|---|---|
| Average high | 78.4°F | 83.2°F | 88.2°F |
| Average low | 58.3°F | 62.8°F | 68.7°F |
| Precipitation | 2.74 in | 2.70 in | 3.66 in |
| Days with 0.10 in or more | 4.0 | 3.9 | 5.3 |
| Spring water | about 74.3°F | about 74.3°F | about 74.3°F |
The water line never moves across the three columns. April’s 83.2°F afternoon sits 4.8 degrees above March and 5.0 below May, and the nights climb the same staircase, 58.3°F to 62.8°F to 68.7°F. Rain is where April wins outright: 2.70 inches over 3.9 wet days against 3.66 inches over 5.3 days in May, nearly an inch more water and a day and a half more of it.
Shift four weeks earlier and you trade 4.8 degrees of afternoon for cooler air and nights averaging 58.3°F, with the wet-day count essentially unchanged at 4.0. Our March page argues that case in full. Shift four weeks later and you buy 88.2°F afternoons at the cost of 5.3 rain days and the opening of the wet season. For a swim in 74.3°F water, hotter air is the one argument for May.
Is April a good time to visit Blue Spring?
Yes, if the water is the reason you are coming. April brings the warmest air of the dry season, the fewest wet days of the three spring months, and a spring holding 74.3°F regardless of any of it. No, if a busy park spoils the day for you: warm Saturdays put real pressure on 187 spaces, and once they are gone the gate stops letting cars in.
March is the fallback, and it is a decent one. Afternoons average 78.4°F, the wet-day count barely moves at 4.0 against 3.9, and the swim itself is identical because the gauge does not know which month it is. You give up five degrees of air and a little of that easy warm-dry feeling on the boardwalk afterward.
April is the only one of the three months where the afternoon air runs nearly nine degrees above the spring while wet days still stay under four.
The last word
Decide on the hour, not on the month. The vent pushes 168 cubic feet per second, replacing its own water faster than anything can cloud it, and Florida Statutes 373.802(5) files Blue Spring among the Outstanding Florida Springs the state protects by name. None of that shifts between March and May. What shifts is the air above it, 83.2°F in April against 78.4°F four weeks earlier, and the number of cars already in the 187 spaces by mid-morning. Set the alarm for the 6:57 a.m. sunrise and walk the boardwalk before you swim.
