Fort Lauderdale in May: Weather, Sea Temperature, Crowds and a Two-Day Plan

FORT LAUDERDALE · FLORIDA · MAY

Rain almost doubles between April and May in Fort Lauderdale, from 3.02 inches to 5.56. Over the same four weeks the ocean warms from 79.7°F to 83.1°F, and the Atlantic hurricane season still does not open until June 1. Daylight on May 15 runs 13 hours 29 minutes, with sunset at 8:01 p.m.

For a trip that adds up to warm-water swimming from the first morning, evenings long enough to eat outside after eight, and a hotel bill carrying Broward County’s 6% transient rental tax on top of 6% state sales tax. Every figure here comes from one thermometer, NOAA station USW00012849 at Fort Lauderdale-Hollywood International, about three miles inland from the sand.

May sits inside a wider state calendar: Florida’s dry season runs November through April, so a May trip catches the first weeks of the wet one. The regional picture is in when to visit Florida, and the neighboring months carry their own numbers in April and June.

Fort Lauderdale weather in May: average highs, lows and rain days

The normals above are NOAA’s 1991-2020 monthly averages for station USW00012849, listed in the record as FT LAUDERDALE HOLLYWOOD AP. That is a real gauge read over thirty years, not a modeled grid cell averaged across several miles of ocean and suburb, and the two kinds of source do not always agree. At that gauge May runs 85.8°F by day and 73.5°F at night. No beachfront station exists to set beside it, so read the high as an airport figure taken three miles inland from the sand.

Broken into days, 5.56 inches reads less oppressively: 7.4 days in an average May record at least a tenth of an inch, roughly one day in four, and only 1.9 days record an inch or more. Two proper soakings and a handful of brief ones, then, with three weeks of the month dry enough to ignore. Florida’s wet season runs on afternoon storms rather than all-day drizzle, as our state guide lays out, so keep the flexible hours for the afternoon.

The spread between 85.8°F and 73.5°F is 12.3 degrees, and the low is a pre-dawn figure: by dinner the air has barely come down. Nobody needs a jacket in a Fort Lauderdale May. The useful items are a packable rain shell for the two inch-days, a second pair of shoes for the day one of them lands, and a dry bag if a kayak launch is on the itinerary.

On May 15 the sun clears the horizon at 6:32 a.m. and sets at 8:01 p.m. local time, 13 hours 29 minutes of daylight by sunrise-sunset.org’s calculation. In practice a beach afternoon can run to 7:30 and still leave light for the walk back, and a start at seven buys two cool hours before the hottest part of the day.

Can you swim in Fort Lauderdale in May? Sea temperature and what it feels like

The Atlantic off Fort Lauderdale averages 83.1°F in May, from the Open-Meteo Marine API over 2015-2024. One qualification changes how you should read it: that is a mean of daily maxima, the warmest reading of each day, so it sits a shade above a true 24-hour average. Tables built on the full day print a lower number for the same month, and neither figure is wrong.

At 83.1°F the water is close enough to the air that entering takes no ceremony at any hour, and a long swim ends for reasons other than cold. Both beach parks hold one designated swimming area each, per Florida’s facilities inventory: Dr. Von D. Mizell-Eula Johnson, with 2.2 miles of beach behind it, and Hugh Taylor Birch, with 0.1 mile.

On wind and swell we have nothing to serve: our sources carry no monthly wave or wind figures for this stretch of coast, and no number is invented here to fill the gap. The calendar is firmer. The Atlantic hurricane season runs June 1 to November 30 and peaks around September 10, per the NOAA National Hurricane Center, which puts all of May outside it. Thunderstorms are a separate matter, so leave the water at the first thunder and come back later.

How busy is Fort Lauderdale in May? Crowds, booking lead time and the Broward County lodging tax

No monthly occupancy or room-rate series for Fort Lauderdale sits in our sources, so no month is crowned the cheapest here. The calendar is a matter of record: Florida’s dry season runs November through April, spring break peaks in March, and the summer school holidays start once May is over. May lands in the gap between them, which is the whole of what can be said without rate data.

Flights arrive through an airport that boarded 17,096,131 passengers in 2024, which the FAA classes a large hub, so seat inventory is deep and the cheapest fares still go first. Parking is the scarcer supply: Mizell-Johnson counts 1,410 spaces, Hugh Taylor Birch 275. For a weekend, fix the room and the car four to six weeks out (est.), and allow a shorter runway for midweek nights. No May event in the city appears in our sources, so none is listed here.

Broward County levies a 6.0% transient rental tax on short stays, filed and paid with Florida’s 6% state sales tax, per Florida Department of Revenue form DR-15TDT. That is 12% on the nightly rate before a property adds anything of its own. Resort fees and parking charges we cannot quote, because no rate data for the city could be read, and a invented dollar figure would be worse than the admission. Our Florida cost guide holds the statewide picture.

The single upgrade that changes a May trip is the walk to the sand. A room a few minutes from the beach turns the 7 a.m. swim and the retreat from a downpour into decisions rather than drives, and it removes the parking question on the two days in the month that drop an inch of rain. Food, car class and the room’s view move the budget without moving the days.

Things to do in Fort Lauderdale in May: Hugh Taylor Birch, Mizell-Johnson and Oleta River State Parks

May is the last full month before the Atlantic hurricane season opens, and the ocean has already reached 83.1°F. In April the water reads 79.7°F, cool enough to shorten a swim. In June the season is open and 9.55 inches of rain fall. That leaves May as the one month here where an all-water plan needs no tropical forecast check with breakfast.

Florida’s Department of Environmental Protection counts its parks item by item, and the 2024 inventory is specific. Dr. Von D. Mizell-Eula Johnson State Park: 2.2 miles of beach, 4,531 feet of boardwalk, 2.6 miles of hiking trail, 1,410 parking spaces, one designated swimming area. Hugh Taylor Birch: 275 spaces, 0.1 mile of beach, 0.3 miles of trail, 60 feet of boardwalk, one canoe, kayak and tube launch. South toward Miami, Oleta River adds 925 spaces, 0.3 miles of beach and two launches on the bay side.

None of those counts moves with the season. What moves is the air above them, 85.8°F in May against 82.9°F in April, and the water at the end of the boardwalk, up 3.4 degrees over the same four weeks. Mizell-Johnson’s 2.6 miles of trail are a different proposition at 85.8°F than in winter: walk them before ten, and keep the 4,531 feet of boardwalk and the swimming area for late afternoon.

One reserve to state: entrance fees and opening hours for all three parks could not be read when we checked on September 11, 2026, because the operators’ pages returned errors or rendered only in a browser. No gate price appears here, and nothing is called free on the strength of a guess. Confirm both at the entrance station on the morning you go.

Fort Lauderdale in May: a two-day itinerary

Day one starts with the 6:32 a.m. sunrise and ends after the 8:01 p.m. sunset. Park at Hugh Taylor Birch by 8:30, when its 275 spaces are the limiting number of the morning, and walk the 0.3 miles of trail before the air reaches 85.8°F. Cross to the beach and swim from ten in water averaging 83.1°F. Eat indoors between one and four, the hours most exposed to the afternoon storms described in our state guide. Back to the sand at 5:30, dinner at eight in daylight.

Day two swaps the ocean for the bay at Oleta River State Park: 925 parking spaces, two canoe, kayak and tube launches, 0.3 miles of beach facing sheltered water. If the forecast turns, reverse the order instead of canceling. Swim in the morning, keep the afternoon indoors, and hold on to the arithmetic: 7.4 wet days out of 31 leaves most afternoons usable. Get out of the water at the first thunder and return an hour later.

Fort Lauderdale in May vs April and June

The three months move in one direction, at different speeds. Daytime highs climb 2.9 degrees from April to May, then 2.6 more into June. Rain climbs faster, 3.02 inches to 5.56 to 9.55, with wet days going 4.1, 7.4, 10.5. The sea follows in the marine series, 79.7°F to 83.1°F to 85.4°F. June’s rain runs more than 70% above May’s while its water is only 2.3 degrees warmer.

Shift four weeks back and you buy dry afternoons: April records 4.1 wet days against May’s 7.4, and 2.54 fewer inches of rain. The cost sits in the water at 79.7°F. Shift four weeks forward and the ocean reaches 85.4°F, but the rain nearly doubles and hurricane season opens on June 1, which makes refundable bookings a different conversation. Both neighbors have their own pages, April and June.

Is May a good time to visit Fort Lauderdale?

Yes for swimmers: 83.1°F water, a designated swimming area at each of the two beach parks, and no hurricane season on the board. No for a trip built on outdoor hours all day, every day, since one day in four records measurable rain and two days in the month drop an inch or more. A family that can move an afternoon indoors loses nothing; a wedding party that cannot has a problem.

If the rain is the deal-breaker, April is the month to move to: 3.02 inches, 4.1 wet days, 82.9°F by day, with the compromise waiting in the sea at 79.7°F. Florida’s dry season runs November through April, and the state calendar ranks the full twelve months rather than these three.

Only in May do you find 83.1°F water with the hurricane season still ahead of you: April’s ocean runs 3.4 degrees cooler, and June’s warmer water arrives with the season already open.

The last word

Book May if what you want is water at 83.1°F and a calendar clear of storm season, and accept one wet day in four as the price. One option that handles a soaking better than a beachfront rate: Oleta River State Park keeps 14 cabins inside the metropolitan area, on the bay side rather than the ocean, per Florida’s 2024 facilities inventory. Their nightly price and booking window we could not read, so call the park before you count on them.
