Key West in August (2025)

Key West in August: Hot Weather, Cool Vibes, and Fewer Crowds

I get it. Key West in August might sound… well… like a heatwave wrapped in humidity. And you’re not wrong—it can be hot. Like, melt-your-key-lime-pie-before-you-finish-it hot. But hear me out: August might just be the perfect time to visit the Southernmost City.

While most folks flock to Key West during the peak tourist season (think winter holidays and spring break), I think the summer months—yes, even the hottest month of the year—are a great time to experience the real, laid-back version of this quirky island paradise. During the summer season, the fewer crowds, off-season hotel rates, and the natural tropical heat practically beg you to slow down, sip something frosty, and savor the natural beauty that surrounds you.

When Is the Best Time of Year to Visit Key West?

That depends—do you love warm weather or dream of gentle breezes? Want plenty of sunshine or prefer cooler weather conditions? Here’s the breakdown:

Winter months (January, February, March) = peak season, higher prices, more tourists, but cooler, breezier weather.
Summer months (June through August) = fewer crowds, better hotel deals, longer daylight hours, and yes, hotter days.
Shoulder season (late July into early August, and then again in fall) = some of the best times to find vacation homes of Key West at more affordable rates.

August may be the hottest month, with average high temperatures in the low 90s degrees Fahrenheit, but the vibe? Relaxed. Local. Fun. And the water temperature? A glorious 87°F. That’s basically bathwater.

What’s the Key West Weather Like in August?

Hot? Yes. Humid? You bet. But don’t let that stop you from enjoying paradise. With a typical average temperature hovering in the 90s (without accounting for humidity), August definitely brings the tropical heat. When you factor in that feels-like temperature, you might start considering whether it’s a “three-shower” kind of day. (Pro tip: it probably is.)

And yes, it’s also the middle of Atlantic hurricane season. That doesn’t mean every day brings a hurricane warning, but you’ll want to keep an eye on the forecast. There’s always a slight chance of showers, and about 20 rainy days during the month. But those usually come in short bursts, not all-day washouts.

The tail end of hurricane season (September and October) typically brings more rain than August, so this might actually be your ideal time to sneak in a trip with just a little planning flexibility.

What To Do in Key West in August (Besides Sweat)

Here’s the good news—there’s no such thing as a bad time in Key West. Even in the hot weather, this island city has you covered (sometimes literally—in glorious AC).

Explore Duval Street

It’s Key West’s heartbeat. During the day, Duval Street might feel quiet and sun-drenched, but by night, it comes alive. One of the best parts? Those air-conditioned bars and the live music. If you’re ready to brave the heat, catch a set at Hank’s, a funky, outdoor venue perfect for cold drinks and good vibes. Want something more chill? Sip wine on the shaded porch at Vinos and watch the world (and chickens) go by.

Mallory Square & the Historic Seaport

At the end of the day, make your way to Mallory Square for the sunset celebration. It’s a classic, carnival-like atmosphere that only Key West can deliver. Street performers, snacks, drinks, and views of the sunset cruise boats silhouetted against the Gulf of Mexico? Yes, please.

Afterward, wander over to the Historic Seaport where you’ll find cute shops, amazing eats, and maybe even some free live entertainment.

Some of my other favorite locations to explore are:

3 Reasons Why Smathers Beach is the Best
Some of our favorite Happy Hour locations
Fort Zach – Why you don’t want to miss this place!
Mel Fisher Maritime Museum
The Custom House and other museums in Key West (hint… most are air-conditioned)

Cool Off on the Water

Cool Off in the Crystal-Clear Waters

There’s no better way to beat the heat than getting on (or in) the water.

Water sports in Key West are a must-do, and August’s warm waters make it an ideal month for:

Snorkeling the vibrant coral reefs
A boat tour to spot marine life
Sailing into the sunset
Jet skiing around the small islands
Visiting Dry Tortugas National Park—one of the most unique national parks in the country, just a ferry ride away

Don’t feel like being that adventurous? Chill by the pool at Dante’s. Their pool parties are legendary and you’ll understand why after a few hours of music, drinks, and splashing around.

Water Activities you don’t want to miss

Indoor Fun for Rainy Days or High Temperatures

Rainy afternoon? Too hot to wander?

Visit the Mel Fisher Maritime Museum or The Custom House—both are cool (literally and figuratively) and filled with fascinating island history.
Catch a movie at the charming Tropic Cinema—seriously, one of my favorite theaters ever.
Head to Kermit’s Key Lime Shoppe for a sweet slice of that iconic key lime pie. (Frozen on a stick and dipped in chocolate? Yes, it exists. Yes, you need it.)
Check out the Florida Keys Eco-Discovery Center—it’s free admission and offers a great overview of the region’s natural beauty and marine life.

You could also lean into the spooky side of things and take a ghost tour. The City of Key West has no shortage of haunted tales and quirky characters.

Events & Happenings in August

August is the start of lobster season, so if you love those claw-free crustaceans, plan to arrive early August and join in on the fun. You’ll also be rolling into the beginning of the shoulder season, so while it’s not packed with popular events, it’s a great time to enjoy the island like a local.

You’re also just ahead of Labor Day weekend, when things start to pick up again heading

Final Thoughts: Is August a Good Time to Visit?

Absolutely. If you’re willing to embrace the tropical storms, the tropical heat, and a little rainy season unpredictability, August can be a great time for adventure. You’ll get clear skies one minute, a quick storm the next, and always the promise of a rum drink waiting just around the corner (speaking of which… still searching for the best rum in town? I’ve got recs for that, too).

And the best part? It’s one of the few times when Key West slows down enough to let you breathe, relax, and really see what makes this island so magical.

So is it the best time of year to visit Key West? For me, it’s any month I get to be there. Even the last thing you think of doing—coming during the hot weather of August—might just turn out to be your new favorite escape.

Need help planning your Key West getaway? I’ve got you covered with guides to the best local attractions, outdoor adventures, beautiful beaches, and—of course—where to find the coldest drinks and best brunch spots. Whether you’re flying into Key West International Airport or road-tripping through the Upper Keys and Key Largo, there’s a good time waiting for you at the end of the road. Just use the search bar or explore the site to start planning your island escape!
