WAKULLA SPRING · MAY · THE MONTH GUIDE
In a May afternoon the air over this corner of the Florida Panhandle averages 87.4°F. The water in the spring holds near 70.3°F, the same reading it gives in January, and that difference is the entire case for going in May rather than in some other month.
What the date gives you is heat on the bank and cold water to jump into, on 4.6 rainy days out of thirty-one. What it takes away is the mild air of April and the short line at the gate that comes with it. Four weeks later, June brings 7.76 inches of rain and the lot fills faster.
THE MONTH AT A GLANCE · WAKULLA SPRING · MAY
May is the first month whose afternoons are hot enough to make 70.3°F spring water feel like a reward, and it lands before June more than doubles the rain.
AIR 87.4°F / 63.0°F · WATER NEAR 70.3°F · 4.6 WET DAYS · 300 PARKING SPACES
Go for: a 17.1°F gap between the afternoon air and the water, long light to 8:25 p.m., and a month that still averages fewer than five wet days.
Think twice before: counting on a warm swim. The spring reads about 70°F every day of the year, and no month heats it up.

Wakulla Spring weather in May: average highs, lows and rain days
| Measure | May figure |
|---|---|
| Average high (air) | 87.4°F |
| Average low (air) | 63.0°F |
| Precipitation | 3.36 in |
| Days with 0.10 in or more | 4.6 |
| Days with 1 in or more | 1.0 |
| Daylight on May 15 | 13 h 44 min |
| Spring water, gauge reading | 70.3°F |
Every air figure here comes from one instrument: NOAA’s NCEI monthly normals for 1991 to 2020, station USW00093805, sitting at Tallahassee about 27 miles from the spring. That matters twice over. It is a real thermometer rather than a reanalysis grid cell, and it stands 27 miles away from the water you came to swim in. The May normals run 87.4°F by day, 63.0°F at night, and 3.36 inches of rain across the month.
Rain reaches the gauge on 4.6 days in an average May, counting only days with 0.10 inch or more. Call it measurable rain about one day in seven. Just 1.0 of those days delivers an inch or more, so a single May afternoon usually carries a third of the monthly total. Over a four-day trip the arithmetic gives you well under one wet day, and the odds of a washed-out weekend are small.
The gap between 87.4°F and 63.0°F is 24.4 degrees, and you feel all of it in one day here. A dawn arrival wants long sleeves and a fleece in the bag; by two in the afternoon that same bag needs a hat, water and something dry to change into. Pack for both ends, not for the average, because the average never happens at any hour.
On May 15 the sun rises at 6:41 a.m. and sets at 8:25 p.m. local time, giving 13 hours 44 minutes of daylight. Practically, that buys a second swim after six o’clock, when the lot has emptied and the afternoon heat has broken. It also means a drive back to Tallahassee in the light rather than in the dark.
How warm is Wakulla Spring in May?
Two numbers answer this, and they point in opposite directions. The air averages 87.4°F at its daily peak and 63.0°F at its overnight low, a 24.4-degree swing. The water sat at 70.3°F (21.3°C) when the USGS gauge at station 02327000 was read on September 11, 2026. That is a single instantaneous reading rather than a monthly mean, and it is the kind of number that barely moves: a spring has no season, only the air above it does.
So the wardrobe splits by clock. Before nine you are dressing against 63-degree air, and the water is the warmer of the two. After lunch you are dressing against 87-degree air, and stepping into 70.3°F will still take your breath on the first step. Most people gasp. Ten minutes later they are back in for a second go, which is the whole appeal of a hot month over a mild one.
Nobody needs to worry about frost in May here, with the average low at 63.0°F, and we found no frost-day count in the station’s May normals, so we publish no figure for it. The cold in May is entirely underfoot, in the spring run, and it never lets up.
How busy is Wakulla Spring in May? Crowds, prices and the demand peak
Florida’s Department of Environmental Protection counts 300 parking spaces at Edward Ball Wakulla Springs State Park in its 2024 facilities inventory. That count, not an opening hour, is what decides a warm Saturday: when the lot fills, the gate closes. We found no occupancy series and no monthly room rates for the area, so we crown no month cheap and no month expensive. What we can say is that May is the first month of the year whose afternoons push people toward cold water.
There is no room to reserve at the gate, and no number of weeks in advance that helps: 300 spaces go first come, first served. The booking decision that actually changes your May morning is where you sleep the night before. Stay close and you arrive in the first hour of the day with the lot half empty. Drive in from farther out and you meet the mid-morning wave with everyone else.
We could not verify the lodging-tax rate for Wakulla County, so we give no percentage. We could not read the park’s entrance fee or its opening hours either: the state park website returns a 403 to automated reads, and fees vary by park and by season, so a price copied from another Florida spring would not transfer here. Call the park, or budget with our Florida cost guide and confirm the gate figure on the day.
Spending more buys neither of the two scarce things in May, since a parking space and a place in the single designated swimming area are not for sale. The one line worth the money is the bed within easy reach of the gate, so the trip starts at sunrise instead of at check-out time. Everything else in the park is walking distance from the lot.
Things to do at Wakulla Spring in May
May opens a gap that April cannot match and June spoils. With the air at 87.4°F and the spring at 70.3°F, the difference is 17.1 degrees, enough to make the cold feel like the point of the day. In April that gap is only 9.9 degrees, and the water reads as punishment rather than relief. June widens it to 20.5 degrees but pays for it with 7.76 inches of rain across 9.9 wet days.
The park itself is compact, and the state has counted it: 1 designated swimming area, 285 feet of boardwalk, 2 observation platforms, 0.2 miles of hiking trail, and the 300-space lot that governs the rest. Those numbers come from the 2024 Recreational Facilities Inventory. No entrance fee appears in that inventory, and we could not read one elsewhere, so no dollar figure for the gate appears below.
What May changes is not the park, it is the contrast inside a single day. At 6:41 a.m. the 70.3-degree water is warmer than the 63-degree air, and the boardwalk rail is cool to the hand. By three in the afternoon the same water is 17 degrees colder than the air, and the two platforms are the shadiest fixed points you have. The trail is 0.2 miles, so shade planning matters more than mileage.
One thing worth knowing before you picture yourself underground: the state names Wakulla Springs for deep cave diving by researchers and scientists, not for visitors wandering in, and it describes Florida’s springs as a chance to probe depths where few will ever go. Manatee sightings are a separate question, and we found no manatee count for May, so we promise none. Our manatee guide covers where and when they are reliably seen.
Wakulla Spring in May: a two-day itinerary
Day one starts early because of the lot. Aim to be parked in the first hour after 6:41 a.m. sunrise, when the air is close to the 63.0°F low and a long-sleeve layer earns its place. Walk the 0.2 miles of trail and the 285 feet of boardwalk while the shade holds, swim around ten when the air has climbed past seventy, then eat and sit out the 87.4-degree peak. Come back to the water near five, with the light good until 8:25 p.m.
Day two is the one to spend on the two observation platforms at first light, then a second swim before the mid-morning arrivals. If the weather turns, remember the shape of May rain: 1.0 day in an average month brings an inch or more, usually concentrated rather than spread out. Shift the swim to the morning, take the indoor part of your day at midday, and let the 4.6-wet-day average work in your favor. Road logistics for the drive out sit in our getting-around guide.
Wakulla Spring in May vs April and June
| Measure | April | May | June |
|---|---|---|---|
| Average high (air) | 80.2°F | 87.4°F | 90.8°F |
| Average low (air) | 54.4°F | 63.0°F | 70.8°F |
| Precipitation | 3.53 in | 3.36 in | 7.76 in |
| Days with 0.10 in or more | 4.3 | 4.6 | 9.9 |
| Spring water (gauge) | Near 70.3°F | Near 70.3°F | Near 70.3°F |
All three columns come from the same NOAA station and the same 1991 to 2020 period, so the comparison is like for like. May runs 7.2 degrees hotter by day than April and 3.4 degrees cooler than June. Rainfall barely moves between April and May, 3.53 inches against 3.36, then jumps to 7.76 inches in June with wet days more than doubling to 9.9. The water column is flat on purpose: the spring reads near 70.3°F in all three months.
Shift four weeks earlier and you gain cooler walking, 54.4-degree nights and a quieter lot, while you lose the heat that makes a cold swim worth having. Shift four weeks later and the afternoon hits 90.8°F, which makes the water better still, but you book into more than twice the rain and a lot that fills sooner. The April case, with its own numbers, is on the April page.
Is May a good time to visit Wakulla Spring?
Yes, if you are coming to swim. May is the month the air finally gets hot enough for 70.3-degree water to read as pleasure rather than endurance, and it does that on 4.6 wet days instead of June’s 9.9. No, if you want warm water or a wilderness day of hiking: the spring never warms, and the park holds 0.2 miles of trail, so anyone planning miles on foot should look at Florida’s bigger parks instead.
If the heat is the deal-breaker, April is your month rather than June. Days average 80.2°F, nights 54.4°F, rain 3.53 inches over 4.3 days, and the drive plus the boardwalk stay comfortable at noon. You give up the shock-and-relief effect at the water’s edge, and you should expect to swim briefly or not at all.
No other month puts 87.4-degree afternoons over 70.3-degree water with fewer than five wet days on the calendar.
The last word
Book the bed near the gate, not the flexible one an hour out, and the 300-space lot stops being a risk. One more thing worth carrying into the trip: Florida law puts this water in a named class, the Outstanding Florida Springs of Statute 373.802(5), a list built from every historic first-magnitude spring plus six written into the statute by hand. That protection is the reason the water you will jump into in May reads the same as the water somebody jumped into in November.
