So, you’re thinking about heading down to the end of the road. Key West. In January.
Honestly, most people think they’re going to get a Caribbean summer in the middle of winter. That’s the first mistake. Don't get me wrong—it’s gorgeous—but if you pack nothing but bikinis and flip-flops, you might find yourself shivering at a sunset celebration with a $40 sweatshirt you bought out of desperation.
January is "Peak Season" for a reason. While the rest of the country is shoveling snow, you're basically living in a postcard. But doing things to do in key west florida in january the right way requires a bit of insider strategy. You've got to navigate the crowds, the weirdly specific festivals, and the fact that the Atlantic Ocean isn't always "bathwater" warm this time of year.
The Weather Reality Check
Let’s talk numbers. Average highs sit around 75°F. Lows? About 65°F.
That sounds perfect, right? It is. Usually. But every now and then, a cold front dips down from the mainland. Suddenly it’s 55 degrees with a biting wind off the water. If you’re planning on snorkeling, keep in mind the water temp hovers around 70-74°F. To a local, that’s "ice water." To someone from Chicago, it’s a miracle.
Pack a light jacket. Seriously. You’ll need it for the ferry rides or the evening strolls down Duval Street.
What to Do When the Sun is Out
If you want to get on the water, January is actually a fantastic time for wildlife. Since the water is a bit cooler, you might spot spotted eagle rays or even a stray manatee near the marinas.
Dry Tortugas National Park
This is the big one. It’s 70 miles west of Key West and only accessible by boat or seaplane. Most people take the Yankee Freedom ferry.

- Pro Tip: Book this months in advance. January sells out fast because the weather is much more tolerable for exploring a massive brick fortress than the sweltering heat of July.
- The Snorkeling: The reef at Fort Jefferson is shallow and protected. Even if the Atlantic is choppy, the moat wall usually keeps things calm.
Fort Zachary Taylor Historic State Park
Forget the "beaches" at the big resorts. They’re often man-made and a bit underwhelming. Fort Zach is where the locals go. It’s got real coral sand (it’s rocky, so bring water shoes) and the best sunset view on the island without the chaos of Mallory Square.
You can tour the Civil War-era fort in the morning and grill out under the Australian pines in the afternoon. It costs about $6 for a vehicle, which is the best deal on the island.
The January Event Circuit
Key West in January isn't just about the beach; it's the intellectual and culinary peak of the year.
Key West Literary Seminar (Jan 8-11, 2026)
This isn't your average book club. For 2026, the theme is "Pay Attention! The Novel, or The Long Form in a Time of Short Attention." You’ll see heavy hitters like Rachel Kushner and Richard Russo hanging out at the San Carlos Institute.
Even if you don't shell out the $825 for the full seminar, there are often free public sessions. It gives the island a smart, buzzy vibe that’s a nice break from the "Margaritaville" tropes.
Key West Half Marathon (Jan 18, 2026)
People fly in from all over the world for this. Running 13.1 miles in Key West is way better than doing it in a frozen park in Ohio. The route takes you past the Southernmost Point and along the Atlantic, and the "Runfest" atmosphere lasts all weekend.
Key West Food & Wine Festival
Late January belongs to the foodies. Think "Grand Tastings" and sunset sails with high-end sommeliers. It’s expensive. It’s crowded. But the seafood—specifically the pink shrimp and stone crab—is at its absolute peak right now.
Transportation: Don't Be That Tourist
Rent a car? Please don't.
Parking in Old Town is a nightmare designed by someone who hates cars. Most spots are "Resident Only," and the ones that aren't will cost you a fortune.
- Bicycles: This is the way. The island is only 4 miles long. You can get anywhere in 15 minutes.
- The Duval Loop: It’s a free bus. It runs every 15-30 minutes and hits all the major spots. Use it.
- Walking: If you stay in Old Town, your feet are your best friends.
The "Tourist Trap" Pivot
Look, you’re going to want to see the Southernmost Point buoy. It’s the law, apparently.
But if you go at 2:00 PM, you will stand in a line of 200 people under a brutal sun just for a photo. Go at 7:00 AM. Or go at midnight. The buoy doesn't move. The light at sunrise is better anyway.
The same goes for Mallory Square. The Sunset Celebration is iconic, with the tightrope walkers and the guy who trains cats to jump through hoops (Dominique, he’s a legend). It’s fun once. But for a second night, grab a bottle of wine and head to the White Street Pier. It’s quieter, more "local," and the sunset is exactly the same one the people at the bars are paying $20 a drink to see.
Eating and Drinking (Beyond Duval)
Everyone goes to Sloppy Joe's. Go ahead, have one drink there so you can say you did. Then, leave.
Head over to Blue Heaven in Bahama Village. Yes, there are roosters walking under your table. Yes, the Key Lime Pie has a mountain of meringue that looks like a hat. It’s worth the wait.
For something more low-key, find El Siboney. It’s a no-frills Cuban spot. Get the Puerco Asado (roast pork) and the yellow rice. It’s cheaper than anything on the waterfront and tastes ten times better.
Actionable Next Steps for Your January Trip
- Book the Dry Tortugas NOW: If you are reading this and your trip is less than three months away, check the Yankee Freedom website immediately. If they're sold out, look into the seaplane—it’s pricier but the views are insane.
- Reserve a Bike: Don't wait until you arrive. Call a shop like Eaton Bikes or We Cycle and have them deliver cruisers to your guest house.
- Check the Cruise Ship Calendar: This is the secret weapon. Google "Key West Cruise Ship Schedule." On days when three ships are in port, avoid Duval Street like the plague. Head to the botanical gardens or the quieter "New Town" areas instead.
- Download the "Duval Loop" App: It tracks the free bus in real-time so you aren't standing on a corner wondering if it's ever coming.
- Pack "The Layer": Bring one high-quality windbreaker or a heavy flannel. When you're on a sunset sail and the wind picks up, you'll be the only person on the boat not shivering.
