WEEKI WACHEE · MAY · 28.5° N
Weeki Wachee Springs State Park sits on its own spring run west of Brooksville, and May is when the air around it turns properly hot: an 88.1°F average afternoon against a 62.6°F dawn, on NOAA’s 1991-2020 normals. A spring has no season of its own, so everything May changes at this park happens above the waterline.
May also lands just ahead of the deluge. The month averages 3.35 inches of rain across 4.4 days with measurable precipitation, while June averages 7.91 inches across 10.9 such days. The other number to carry is 255: that is how many parking spaces the state counts at the park, and when the lot fills, the gate closes.
MAY AT A GLANCE · WEEKI WACHEE SPRINGS
May gives Weeki Wachee its first properly hot afternoons, 88.1°F on average, with rain on only 4.4 days, and the ceiling on a busy Saturday is the park’s 255-space lot rather than the sky.
AVG HIGH 88.1°F · 4.4 WET DAYS · 255 PARKING SPACES · 13H38 OF DAYLIGHT ON MAY 15
Go for: hot air over cool spring water, 13 hours 38 minutes of daylight on May 15, and a month averaging 3.35 inches of rain against June’s 7.91.
Think twice before: arriving late on a weekend: the state counts 255 parking spaces, and when the lot fills, the gate closes.

One caveat before the normals below: they describe the air, measured at an inland airport. The run itself has its own temperature, and we found no published water reading for Weeki Wachee, so we give no water figure and no manatee count.
Weeki Wachee Springs weather in May: highs, lows and rain days
| Measure | May normal |
|---|---|
| Average high | 88.1°F |
| Average low | 62.6°F |
| Precipitation | 3.35 in |
| Days with 0.10 in or more | 4.4 |
| Days with 1 in or more | 1.0 |
| Daylight on May 15 | 13h 38m |
These figures come from NOAA NCEI’s 1991-2020 monthly normals at station USW00012818, Brooksville Hernando County Airport, about 27 miles (44 km) inland from the spring. May averages an 88.1°F high, a 62.6°F low and 3.35 inches of rain. That is a station thermometer rather than a reanalysis grid cell, and the distance is the trade: a real instrument, recording a few ridges away from the water you came for.
Rain arrives in episodes. An average May records 4.4 days with at least 0.10 inch, roughly one day in seven, and 1.0 day with an inch or more. That single heavy day can carry close to a third of the month’s total, so budget one lost afternoon across a long weekend and keep the rest of the plan intact.
Between the 62.6°F dawn and the 88.1°F afternoon sits 25.5°F of swing, and that is what fills the bag. A long-sleeve layer covers the first hour by the water, a hat and shade cover the last. Quick-dry clothing handles both ends of a day that starts cool and wet and finishes hot and wet.
On May 15 the sun rises at 6:37 a.m. and sets at 8:15 p.m. local time, giving 13 hours 38 minutes of daylight, per sunrise-sunset.org. Plan around that late sunset: a 5 p.m. put-in still leaves three usable hours of light. We could not verify the park’s own opening and closing hours, so confirm those before you count on either end of the day.
How warm is Weeki Wachee Springs in May?
The May normal high reaches 88.1°F and the normal low 62.6°F, a spread of 25.5°F between the warmest and coolest hours of an average day. April’s spread is wider still, 82.8°F down to 55.7°F. What May lifts is the floor: seven degrees of overnight warmth on April, which is the difference between a shivery start and a pleasant one.
In practice that means a light layer at the picnic tables before nine and nothing over a swimsuit after eleven. Coming out of spring water at 8 a.m. into 62.6°F air is the moment people underestimate, so pack a second towel. From about midday the afternoon does the drying for you.
On freezing nights, our source gives no frost-day count for May at the Brooksville station, so we publish none, and a 62.6°F average low leaves no room for one in a normal year. The water question we cannot answer with a number at all: no published temperature for the spring run turned up in our reading, so we give no degrees and no comparison.
How busy is Weeki Wachee Springs in May?
We found no occupancy series and no monthly room-rate data for Hernando County, so we crown no month cheap or expensive. What the state does publish is capacity: 255 parking spaces at Weeki Wachee Springs State Park, counted in the Florida DEP’s 2024 facilities inventory. On a warm Saturday that figure sorts the day long before any price does.
Capacity turns arrival time into the real booking decision. No day-entry reservation system appeared in our sources, so the levers you hold are the clock and where you sleep the night before. A bed close enough for a 7 a.m. start does more for a May Saturday than an upgraded room does. Our Florida lodging guide sorts the regions.
We could not verify the county lodging-tax rate, so no percentage appears in our numbers. Assume the quoted room rate is not the final line on the bill, and build the tax line into the budget anyway. Our trip-cost guide lays out how the tiers stack across a Florida week.
Money buys one useful thing here in May, and that is an earlier morning. The park holds a single designated swimming area and a single canoe, kayak and tube launch, both counted by the state, so every visitor who clears the gate funnels through the same two points. Paying to shorten the drive in beats paying for anything you can add once the lot is full.
Things to do in Weeki Wachee Springs in May
May is the swimming month that June undercuts. The air averages 88.1°F, warm enough that spring water reads as relief, and rain interrupts only 4.4 days against June’s 10.9. April’s 82.8°F afternoons make excellent walking weather and a far less persuasive argument for getting in.
The park runs on a short list the state counted in 2024: 1 designated swimming area, 1 canoe, kayak and tube launch, 255 parking spaces. Florida Statutes 373.802(5) defines Outstanding Florida Springs as every historic first-magnitude spring the Florida Geological Survey identifies, plus six named by hand in the law. We did not verify which of those two routes covers Weeki Wachee, so we make no claim about its listing.
What May changes at those two points is the contrast. The run holds its temperature all year while the air climbs 5.3°F from April to May, and that widening gap is the whole sensation of a spring swim. In April the first minute is a shock with little payoff. In May the same minute pays by noon, when the airport thermometer reads near 88°F and shade at the picnic area matters.
On what a day costs, we came up short: floridastateparks.org returns 403 to automated reads, so we could not verify an entrance fee, an opening hour or any free day in May. Call the park or ask at the gate before you build a morning around either. Our know-before-you-go guide covers the practical Florida layer around it.
Weeki Wachee Springs in May: a two-day itinerary
Day one starts at the gate. Sunrise is 6:37 a.m. in mid-May and 255 spaces go round, so park early and swim first, while the air is still climbing toward its 88.1°F average peak. Take the middle of the day in shade, which is also when Florida’s wet season tends to deliver its storms. Save the paddle launch for late afternoon: with sunset at 8:15 p.m., a 5 p.m. put-in has daylight to spare.
Day two repeats the water in the morning and puts the driving after lunch, when the sky is least reliable. If the forecast turns, swap the order: an average May carries one day with an inch or more of rain, and that is the day to spend on the road with the wider Florida list rather than in a tube. A second morning also gives the launch a shot at a quieter hour.
Weeki Wachee Springs in May vs April and June
| Measure | April | May | June |
|---|---|---|---|
| Average high | 82.8°F | 88.1°F | 90.2°F |
| Average low | 55.7°F | 62.6°F | 69.9°F |
| Precipitation | 2.18 in | 3.35 in | 7.91 in |
| Days with 0.10 in or more | 3.4 | 4.4 | 10.9 |
Highs run 82.8°F in April, 88.1°F in May and 90.2°F in June, putting May 5.3°F above April and 2.1°F below June. Rainfall is where the three months separate: 2.18 inches, then 3.35, then 7.91. Measurable rain days go 3.4, 4.4, then 10.9. June more than doubles May’s count in a single step, all from the same NOAA station series.
Shift four weeks back and you trade 5.3°F of afternoon heat for a drier month at 2.18 inches and a 55.7°F dawn that makes an early swim a colder proposition. Our April guide works through that trade. Shift four weeks forward and the afternoons hit 90.2°F, with 10.9 wet days and 7.91 inches of rain attached, better than double May’s total.
Is May a good time to visit Weeki Wachee Springs?
Yes if the trip is built around getting in the water. May pairs an 88.1°F average afternoon with only 4.4 wet days, and hot air is what makes a cold spring worth entering. No if you need a guaranteed schedule: 255 spaces is a hard ceiling, and since we could not verify hours or fees, a late arrival can end at a closed gate with nothing to appeal to.
If that trade does not suit, take April: 2.18 inches of rain, 3.4 wet days and an 82.8°F afternoon that makes the walking and the picnic areas comfortable, with a 55.7°F start to each morning as the price. Families who want the shortest odds on a dry weekend will find April the safer bet, and the April page runs the same numbers.
No other month in this stretch pairs an 88°F afternoon with fewer than five wet days: April is cooler, June is wetter, and May holds the middle alone.
The last word
Book the bed that gets you to the gate early and treat the afternoon as negotiable. With 255 spaces and 4.4 wet days, May rewards the visitor who moves first and shrugs off one washed-out hour. One figure to carry out the door: by June the average overnight low stands at 69.9°F, which makes May the last of these three months with a genuinely cool start, 62.6°F at sunrise and 88.1°F by mid-afternoon.
