Honestly, if you're checking the key west 14 day forecast right now, you're probably dreaming of escape. Most of the country is shivering, and the idea of a tropical breeze sounds like heaven. But here is the thing: Key West in mid-January is a bit of a trickster. You see these "75 and sunny" numbers and think it’s strictly bikini weather.
It isn't. Not always.
Right now, we are looking at a classic January pattern. Today, Tuesday, January 13, we’ve got a comfortable high of 74°F with a bit of a northeast breeze. It feels like the Florida everyone imagines. But if you look ahead at the next two weeks, there is a shift coming that might catch you off guard if you only packed flip-flops.
The Reality of the Key West 14 Day Forecast
We've got a cold front moving in around Thursday, January 15. The high stays at 74°F, but the low is going to drop to 61°F. That might not sound "cold" to someone in Chicago, but with a 26 mph wind coming off the water? It’s chilly. Basically, you’re going to want a hoodie for that sunset sail.
By Friday, the daytime high actually dips to 68°F.
This is the nuance people miss. Key West is a tiny island. You are surrounded by water that is currently hovering around 74°F. When a north wind hits that water and blows across the land, the humidity drops—which is great—but the "real feel" can be much lower than the thermometer says.
What the Next Two Weeks Actually Look Like
- Mid-Week (Jan 14-15): Mostly cloudy transitioning into a breezy Thursday. Rain chances are low—around 20% to 35%—so don't expect a washout. These are usually quick showers that blow through in ten minutes.
- The Weekend Dip (Jan 16-18): Expect plenty of sun but cooler air. Highs will struggle to get past 70°F. If you’re planning on Smathers Beach, the sun will be warm, but the second a cloud passes, you’ll feel the bite in the wind.
- The Second Week (Jan 19-22): We see a slow climb back up. By Monday, January 19, it’s back to 68°F, but by the following Thursday, we are looking at 75°F again.
Consistency is rare in January. One day you're sweating in line at Blue Heaven for lobster benedict, and the next you’re buying an overpriced "Key West" sweatshirt because you didn't believe the forecast.

The "Dry Season" Misconception
Everyone calls this the dry season. It’s true that we don't get the massive tropical deluges of September, but "dry" doesn't mean "desert."
In the key west 14 day forecast, you'll see a lot of 10% or 20% rain chances. In Key West lingo, that usually means a "sprinkle-and-run." The clouds move fast here. You can literally stand on Duval Street, see it pouring three blocks away, and stay perfectly dry.
The real weather story in January isn't rain; it's the wind.
The Florida Keys are uniquely exposed. Unlike Miami, which has skyscrapers to break the gust, Key West is flat. A 20 mph wind is a constant presence. It affects everything: the clarity of the water for snorkeling, the chop on the ferry to the Dry Tortugas, and whether or not you can keep your hat on while biking.
Water Temperatures: Can You Actually Swim?
The ocean right now is about 74°F.
For locals, that is freezing. We won't touch the water without a 3mm wetsuit. For visitors from the North? It feels like a heated pool. However, if you are heading out to the reef with a company like Fury or Danger Charters, keep in mind that the boat ride back is where you'll freeze. Wet skin plus 20-knot winds plus 68-degree air is a recipe for shivering.
Why This Specific Forecast Matters for Your Plans
If you are looking at the window between January 15 and January 20, you need to adjust your expectations for "beach days."
These are actually the best days for walking the historic district.
Without the oppressive 90% humidity of summer, you can actually hike up the Key West Lighthouse or wander through the Hemingway House without needing a shower immediately after. The air is crisp. The light is fantastic for photos. Honestly, the sunsets are often better when there’s a cold front nearby because the high-altitude clouds catch the colors differently.
A Note on Local "Cold"
It’s worth mentioning that Key West has no record of frost. Ever.
You don't need a parka. You just need layers. The "Conch" (local) uniform in January is a pair of shorts with a heavy hoodie. It looks ridiculous until the sun goes down and that ocean breeze kicks in. Then, you'll get it.
Actionable Tips for the Current Forecast
Don't let a "low" of 60°F ruin your trip. Just play it smart.
Pack a windbreaker. It’s more important than an umbrella. It blocks the salt spray on boats and keeps the chill off during dinner at an outdoor spot like Louie’s Backyard.

Check the marine forecast, not just the land one. If the land forecast says "Sunny and 70," but the marine forecast says "Small Craft Advisory," your snorkeling trip is probably going to be bumpy and the water will be murky from kicked-up sand.
Book your indoor activities for the weekend. If the 16th and 17th look breezy and cool, that is the perfect time to visit the Mel Fisher Maritime Museum or catch a show at the Tennessee Williams Theatre.
Don't cancel because of a 30% rain chance. Seriously. It almost never rains for the whole day in January. The "rain" is usually a beautiful dramatic cloud that passes in the time it takes to drink a Margarita.
The next 14 days in Key West are shaping up to be a beautiful, if slightly brisk, slice of tropical winter. It’s far better than shoveling snow, just remember that the "tropics" have moods too. Keep an eye on the wind speeds, pack a light jacket, and you’ll be the only one on Duval Street who isn't shivering when the sun dips below the horizon.
