You probably packed flip-flops and a tank top. Most people do when they see "Florida" on the boarding pass. But if you're looking at the weather forecast fort myers florida 14 day outlook right now, you might want to dig that light jacket out of the back of your closet.
It's cold. Well, Florida cold.
As of mid-January 2026, Southwest Florida is dealing with a classic atmospheric tug-of-war. We just saw a cold front slam into the Gulf Coast on Thursday, January 15, that sent mercury levels plummeting. If you woke up this morning, Friday the 16th, you likely saw temperatures in the low 40s or even upper 30s. That’s a massive shock to the system when you're used to the 80-degree humidity of the Caloosahatchee.
The 14-Day Breakdown: What to Actually Expect
The immediate future is a bit of a rollercoaster. Honestly, "erratic" is the best word for it. Here is the play-by-play for the next two weeks in the City of Palms.
The Immediate Chills (Days 1–4)
Today, Friday, is staying crisp. Don't expect to break 65°F. It's bright and sunny, sure, but that wind coming off the water has a bite. Saturday (Jan 17) starts the slow climb back up, hitting the mid-70s, though we might see some stray sprinkles late in the evening. By Sunday, the clouds move in, and while it stays in the 70s, it won't be that postcard-perfect beach weather.
The Rebound (Days 5–9)
Monday, Jan 19, brings another dip—sunny but back down to a high of 67°F with a chilly low of 38°F. Yeah, you read that right. 38 degrees. If you have tropical plants on your lanai, you’ve basically got to bring them in or cover them.

Once we clear Tuesday, things start looking up. We’re talking a steady rise:
- Wednesday: 75°F
- Thursday: 82°F
- Friday: 80°F
By the end of next week, the humidity starts creeping back. You'll feel that familiar Florida "soupiness" in the air by Friday afternoon, especially with a 50% chance of showers late in the day.
The Late January Outlook (Days 10–14)
Moving into the last week of the month (Jan 25–30), we settle into a very predictable pattern. Highs will hover between 78°F and 82°F. Lows will stay in the comfortable mid-60s. It’s perfect golf weather. It’s "eat dinner outside without melting" weather. Just keep an eye on Thursday, Jan 29—current models suggest some passing showers that might ruin a tee time.
Why Southwest Florida Weather Is So Moody in January
People think Florida is just "hot" or "less hot." That’s a total myth.
The weather forecast fort myers florida 14 day is dictated almost entirely by the jet stream. In 2026, we're seeing an acceleration in warming trends globally, but that actually makes our winter cold fronts more volatile. Robert Rohde, a chief scientist at Berkeley Earth, has noted that while the planet is warming, the "linear trends" we used to rely on are shifting.

What does that mean for your vacation?
It means the temperature can swing 40 degrees in 24 hours. We call it "The Great Florida Layering." You start the morning in a hoodie and end the afternoon in a swimsuit.
Rain or Shine: The Probability Factor
January is historically one of our driest months. The average rainfall is usually around 2 inches. However, 2026 has been a bit wetter than the historical 1991-2020 normals. We’re currently seeing about a 15% to 20% daily chance of rain, which usually manifests as "quick bursts" rather than day-long washouts.
If you’re heading to Fort Myers Beach or Sanibel, the sea temperature is hanging around 68°F to 70°F.

Maybe for a Canadian. For most locals, that’s "polar plunge" territory. If you want to get in the water, stick to the heated hotel pools for the next 14 days.
Survival Tips for the Fort Myers 14-Day Cycle
Don't let the "30-degree morning" headlines scare you off. Southwest Florida in January is still better than almost anywhere else in the country right now.
- Check the wind, not just the temp. A 70-degree day with a 15-mph wind off the Gulf feels like 60. If you're going on a sunset cruise, double whatever layers you think you need.
- Trust the morning "feels like" temp. Because the humidity is lower in winter, the air doesn't hold heat. When the sun goes down, the temperature drops like a rock.
- The UV index is still a liar. Even if it's 65 degrees, the Florida sun is intense. You can get a nasty sunburn in January because you don't feel the heat on your skin.
- Morning Fog is Real. We’ve been seeing patchy fog lately around the I-75 and Page Field areas. If you’re driving early, give yourself extra time.
Basically, the 14-day outlook is a tale of two climates. You’re going to experience a mini-winter for the first few days, followed by a glorious return to the tropical vibes Fort Myers is famous for.
Next Steps for Your Trip
Keep your eye on the local radar if you're planning outdoor events for the weekend of Jan 23-24, as those "showers late" forecasts in Florida often turn into localized downpours. Pack a versatile windbreaker and a pair of long pants for the evenings, but don't ditch the sunscreen—the UV index is still hitting a 5 (Moderate) most afternoons.
