What to Pack for Key West in May: What I Actually Used and What I Didn’t

If you are wondering what to pack for Key West in May, prepare for heat.

We were lucky and had beautiful weather during our trip, with plenty of sunshine and no rain, but the temperatures were still intense. Most days were in the high 90s, and the real feel was often over 100 degrees.

The good news is that evenings cooled down into the mid-70s and felt wonderful. Mornings were also fairly comfortable until around noon. After noon, the heat picked up fast, so cold water, shade, and breaks made a big difference.

After spending several days walking around Old Town, eating through Key West, swimming, exploring, and taking a Dry Tortugas day trip, these are the items I was glad I packed and a few things I would do differently next time.

If this is your first trip, I would also read my Key West Travel Guide for First Time Visitors because packing makes more sense once you know how much walking, eating, sweating, and sunset-chasing is involved.

Key West Weather in May

Key West in May is hot, sunny, humid, and very walkable if you pack correctly.

This is not a destination where I would bring a suitcase full of “just in case” layers. During our trip, I never needed a jacket, sweater, jeans, or anything heavy. I needed lightweight clothes, comfortable shoes, sunglasses, cold water, and hair ties.

Mornings were the easiest time to explore. We could walk around Old Town, get breakfast, visit attractions, or take photos without feeling like we were melting immediately.

By midday, the heat was much stronger. If you are planning a May trip, I would build your days around mornings, evenings, pool breaks, shaded stops, and indoor meals when possible. My Key West 3 Day Itinerary for First Time Visitors is a good next step if you want to see how I would structure the days without cramming everything into the hottest part of the afternoon.

Evenings were the best surprise. Once the sun went down a little, Key West felt so much more comfortable. Dinner, sunset, and walking around after dark were much easier than trying to do everything in the middle of the afternoon.

Lightweight Clothes Are Essential

This is not the trip for heavy fabrics.

During the day, I mostly wore:

  • Shorts
  • Stretchy skorts
  • Tank tops
  • Lightweight tops
  • Flowy casual outfits

The humidity is no joke, and you will appreciate anything lightweight and breathable.

For a Key West packing list in May, I would focus on clothes that feel easy to wear in direct sun and humidity. Think cotton, linen, athletic-style skorts, breezy dresses, and tops that are not going to cling to you all day.

If you are wearing dresses or skirts in the heat, Thigh Society shorts are a good thing to pack.

This is also not the trip where I would pack a bunch of complicated outfits. You are walking, sweating, going in and out of restaurants, stopping near the water, and possibly changing for dinner later.

Cute is fine. Heavy is not.

What to Wear in Key West During the Day

For daytime in Key West, I would pack casual outfits that can handle heat, walking, and a little sweat.

Old Town Key West is very walkable, but that also means you may be outside much more than you expect. Between Duval Street, Mallory Square, the Historic Seaport, the Hemingway House, coffee shops, restaurants, and random wandering, we spent a lot of time outside.

A good daytime outfit for Key West in May would be something like:

  • A tank top with shorts
  • A stretchy skort and lightweight top
  • A casual sundress
  • A romper
  • A flowy set
  • Lightweight linen or cotton pieces

I would avoid anything thick, tight, or fussy. If you are already questioning whether something will be too hot, it probably will be.

Bring Comfortable Walking Shoes

Key West is surprisingly walkable. Between Duval Street, Old Town, Mallory Square, the Historic Seaport, and all the restaurants, we walked a lot more than I expected.

I mostly wore flats because they worked well with my outfits, and they were fine most of the time. But there were definitely moments when tennis shoes would have been more comfortable.

The downside is that tennis shoes can feel hot during the day, especially in May.

If you are trying to balance comfort and style, a comfortable sandal or supportive flat is a great option. I would not pack shoes that need to be broken in, and I definitely would not plan to walk around Key West all day in anything uncomfortable just because it looks cute.

This is a walking destination, even if it does not feel like one when you are packing.

Pack Casual Dinner Outfits

One thing that surprised me about Key West is how laid-back it feels.

Even at nicer restaurants, people were not overly dressed up. You can absolutely wear a cute dinner outfit, but you do not need to pack like you are going to a formal resort.

For dinner, I wore:

  • Flowy dresses
  • Rompers
  • Lightweight pants
  • Sleeveless tops

That felt right for Key West.

I did bring a pair of heels for a nicer dinner, but I ended up changing into them once I arrived at the restaurant rather than walking around Key West in them. That was the correct decision.

The sidewalks, heat, walking distances, and general Key West casualness do not make heels especially practical. If you want them for photos or a nicer dinner, bring one pair. I would not pack multiple pairs.

Skip the Jacket

I did not use one.

Not once.

Not during the day.

Not at night.

Not in restaurants.

Many restaurants in Key West are open-air or partially outdoors, so I never encountered the freezing restaurant air conditioning that sometimes makes me want a sweater.

If you are visiting Key West in May, I would leave the jacket at home.

I know there is always the little packing voice that says, “But what if I get cold?” I usually listen to that voice. In Key West in May, that voice was wrong.

Put Your Hair Up

This was probably my biggest packing mistake. I wore my long hair down during the first day and immediately regretted it.

Between the heat, humidity, and walking, I quickly realized fun updos, ponytails, braids, and messy buns were much more practical during the day. I still wore my hair down for dinner, but daytime was a different story.

If you have long hair, pack more hair ties than you think you need. Bring clips, scrunchies, a claw clip, whatever works for your hair. This is not the trip where I would rely on one tiny emergency hair tie at the bottom of your bag. The humidity will win.

Save this for later on Pinterest so you don’t forget it.

Do Not Forget Sunglasses

I used my sunglasses constantly.

Key West is incredibly bright and sunny, especially when you are walking near the water.

If you normally leave home without sunglasses, this is not the trip to do that. I would pack a pair you actually like wearing and maybe a backup pair if you are someone who loses things on trips.

Between the water, white buildings, sidewalks, boats, and full sun, your eyes will need them.

Bring a Refillable Water Bottle

My Brita water bottle was one of my most-used items.

I would fill it with ice at the hotel each morning and then refill it throughout the day at restaurants and attractions.

Having cold water while walking around Old Town made a huge difference.

This seems basic until you are walking in Key West in May and realize how often you want water. Buying bottles all day gets annoying, and it is easier to stay hydrated if you already have one with you.

I would not do Key West in May without a refillable water bottle.

Pack a Swimsuit

Even if you are not planning a beach vacation, once that hot heat hits you, you may change your mind. We did. Ha.

We ended up swimming every day, whether it was at our hotel pool or during our Dry Tortugas excursion. If you are curious about where we stayed and why the hotel pool was very much appreciated in May, I wrote more about it in my Hotel Marquesa Review: Is This the Best Boutique Hotel in Key West?

A swimsuit ended up being one of the most-used items in my suitcase.

Even if Key West is not a classic “lay on the beach all day” trip for you, I would still pack at least one swimsuit. If your hotel has a pool, you will probably use it. If you are taking a boat trip, snorkeling excursion, beach stop, or Dry Tortugas day trip, you will definitely want one.

For May, I would bring at least two swimsuits if you have room. That way one can dry while you wear the other.

Bring Your Own Snorkel Gear

If snorkeling is even remotely on your vacation wish list, bring your own gear. The Florida Keys are home to North America’s only coral barrier reef, and there are plenty of opportunities to get in the water.

We used our snorkel mask at Dry Tortugas, but there are many other snorkeling opportunities throughout the Keys as well. If you are planning that day trip, my How to Visit Dry Tortugas National Park: Everything You Need to Know breaks down the full experience.

Could you rent or use provided gear on certain tours? Yes. But I prefer having my own snorkel mask because I know it fits, I know it is comfortable, and I am not trying to figure it out for the first time once I am already in the water.

If snorkeling is a major part of your Key West trip, bring your own gear if you can.

Water Shoes Are Worth Packing

Many Florida Keys beaches are rocky, coral-filled, or rougher than visitors expect. I was very glad I had water shoes.

They made entering the water much more comfortable and protected my feet from sharp rocks and coral.

This is especially helpful if you are used to soft sandy beaches where you can walk straight into the water without thinking about it. The Keys are different. The water can be gorgeous, but the entry points are not always soft and easy.

Water shoes do not take up much room, and I was glad I had them.

Bring a Quick-Dry Beach Towel

We packed a large quick-dry beach towel that was big enough for both of us. It took up very little room in our luggage and came in handy multiple times throughout the trip.

I liked having one large towel instead of packing bulky beach towels. It worked for pool time, water stops, and the Dry Tortugas excursion. A quick-dry towel is especially useful if you are trying to keep your luggage lighter or if you are changing locations during a Florida Keys trip.

A Few Extras I’d Still Pack

A few smaller items also helped more than I expected.

For sunscreen, I like having both body sunscreen and face sunscreen because Key West is not a casual sun situation. Coola spray sunscreen is easy for reapplying during the day, and Supergoop face sunscreen is good if you want something that feels better on your face.

I would also bring a portable phone charger, especially if you are using your phone for maps, photos, restaurant reservations, and directions all day.

For bags, you do not need anything huge, but you do need room for sunglasses, water, sunscreen, and whatever random thing you bought because you walked into a shop for “just a minute.” A phone and wallet crossbody strap is also helpful if you want to keep your hands free while walking around, taking photos, or carrying your water bottle.

FAQs About Packing for Key West in May

Is Key West hot in May?

Yes. During our trip, the real feel was often over 100 degrees, so I would pack for heat, humidity, and lots of sun.

Do you need a jacket in Key West in May?

I did not need a jacket at all. Not at night, not during the day, and not inside restaurants. If I visited Key West in May again, I would leave the jacket at home.

What should I wear in Key West in May?

I would wear lightweight, breathable clothes. Shorts, skorts, tank tops, casual dresses, rompers, and flowy outfits all worked well. For dinner, Key West still felt laid-back, so I would bring cute but comfortable outfits instead of anything too formal.

Should I pack a swimsuit for Key West?

Yes. Even if you are not planning a beach-heavy trip, I would still pack a swimsuit. In May, once the heat hits, pool time becomes very appealing.

Final Thoughts on What to Pack for Key West in May

If I could give one packing tip for Key West in May, it would be this:

Pack for heat.

Then pack for even more heat.

The key is staying cool, comfortable, and hydrated while you are out exploring. Lightweight clothing, comfortable shoes, sunglasses, a refillable water bottle, and a swimsuit will get far more use than anything fancy you bring.

And if you have long hair like I do, learn from my mistake and pack plenty of hair ties.

Sky Ranch Lodge, Sedona. Booked it for the location, stayed for the sunsets.

This is not a five-star resort with ten restaurants and a spa menu the length of a novel. It’s a family-owned boutique hotel on Airport Mesa that knows exactly what it’s good at: red rock views from basically everywhere and one of the best sunset spots in town, private, with maybe four other couples instead of a crowd.

We booked a Premier Rim Room and I’d do it again in a heartbeat. Watched the sunset from our own patio one night and it’s still one of my favorite moments of the whole trip.

✨ Six acres of botanical gardens to wander morning and evening
✨ Pool + hot tub that hit exactly right after a day of hiking
✨ On-site food truck for easy breakfasts and lazy room service nights
✨ Complimentary shuttle so you’re not fighting Sedona parking
✨ Robes, slippers, and a staff that felt genuinely happy to help

Two stays in and I’d book it again without a second thought. This is where to stay in Sedona if you want it to actually feel like Sedona.

Thank you to @skyranchlodge for having us, link in bio for the full review 🌵
Four hours on a train through a canyon you can’t reach by car — such a fun experience! We picked the indoor seats with unlimited access to the open-air viewing car, which honestly felt like the only right call. You’re not stuck in an assigned seat the whole time we bounced between the two, snacks in hand, chasing the best light.

The scenery is the whole point. Red rock cliffs, the Verde River, a 734-foot tunnel, historic trestle bridges views most people visiting Sedona never see, because you literally can’t drive to them.

The charcuterie box that comes with your ticket is shockingly filling ✨ so skip lunch at the Copper Spike Café beforehand, save your appetite for dinner back in Sedona.

Four hours with no stops did start to feel long by the end, but the trade-off for scenery like this? Worth it.

Would I ride it again? Yes. Would I buy lunch first again? No.

I ate chilaquiles while a Cessna taxied past the window, and that’s just a normal Tuesday breakfast in Sedona.

@mesa_grill_sedona sits right beside the Sedona Airport Scenic Lookout, so along with your food you get red rock views stretching in every direction and a front-row seat to tiny planes lifting off. Chef Mercer Mohr runs the kitchen, serving up Southwestern comfort food from breakfast through dinner, chilaquiles, elevated diner classics, burgers, steaks, seafood, all of it.

The view is what pulls people in the door, but the food actually holds its own. Good enough that this place stays packed with locals, not just tourists passing through on their way to the lookout. It also picked up the 2025 Tripadvisor Travelers’ Choice and OpenTable Diners’ Choice awards, so it’s not just me saying it.

Indoor seating if you want the AC, a pet-friendly patio if your dog’s along for the trip. Either way, get there before plane-spotting turns into a wait for a table.

Yes, it’s only July. Start planning anyway. Fall books faster than people expect, and a few of these destinations are worth getting ahead of. Here are five places worth putting on your radar right now.

Ireland: Cooler temps, moody skies, dramatic coastline fall was made for it. Tourist crowds drop, the green stays, and the whole country feels a little more like itself.

Great Smoky Mountains, TN/NC: Fall foliage in the Smokies is the real thing. The color peaks mid-October and the views from the ridgelines are hard to argue with. It’s also one of the most visited national parks in the country, so going on a weekday makes a real difference.

New York City: Fall is NYC at its best comfortable temps, the energy of the city shifting into a new season, and every neighborhood doing something worth showing up for. It’s also just a great walking city when it’s not brutally hot.

Japan: Fall foliage season is as good as spring cherry blossoms and somehow less talked about. The colors are dramatic, the temples and gardens are stunning, and it’s worth planning around peak dates by region.

Mystic, Connecticut: Small, walkable, genuinely charming Mystic in fall feels like exactly what a New England autumn is supposed to look like. Easy to pair with a broader New England road trip if you want to extend it.
