You're probably checking your weather app right now because you’re tired of the gray slush up north or you’re planning that big spring break trip to the Gulf. Most people think Florida is just "hot" year-round, but if you’re asking what's the temperature in Fort Myers Florida, the answer depends entirely on whether you're standing in the sun, in the shade, or in the middle of a freak January cold snap.
Right now, as of January 13, 2026, Fort Myers is sitting at a pretty comfortable 76°F. It’s mostly cloudy today, but honestly, that’s a blessing. Without the clouds, the South Florida sun can feel like a heat lamp even in the "winter."
But don't get too comfortable. By Thursday, a cold front is expected to drop the overnight low to a bone-chilling (for us) 37°F. Yes, you read that right. In the same week, you can go from a bikini at Fort Myers Beach to a puffer jacket at the Edison and Ford Winter Estates.
The Reality of Fort Myers Weather: Season by Season
It's a common mistake to assume "Tropical" means "Constant." Fort Myers is technically a humid subtropical climate. That basically means we have two real seasons: the Dry Season and the "I can't breathe because the air is soup" Season.
The Dry Season (November to April)
This is when the "Snowbirds" arrive, and for good reason. The humidity drops, and the daily highs usually hover between 74°F and 81°F. It’s glorious.
The nights are the wild card. January is officially the coldest month, with an average low of 54°F. However, as we're seeing this week, those averages are just math. Real life involves occasional dips into the 30s and 40s when Arctic air pushes down the peninsula.

The Rainy Season (May to October)
Around mid-May, everything changes. The wind shifts. The humidity spikes. Suddenly, the question of what's the temperature in Fort Myers Florida becomes less important than the "Feels Like" temperature.
In August, the high is usually 92°F. Sounds manageable? Add 80% humidity, and the Heat Index (how it actually feels on your skin) regularly hits 105°F or higher.
What No One Tells You About the "Daily 4 PM Rain"
If you look at a forecast in July, you’ll see a rain icon every single day. Don't cancel your boat rental.
Fort Myers experiences "convective" rainfall. The heat of the day builds up, the sea breeze pushes in from the Gulf, and boom—you get a massive thunderstorm at 4:00 PM. It lasts 45 minutes, cools the air down by ten degrees, and then the sun comes back out to turn the streets into a giant sauna.
- June: 9.66 inches of rain (The wettest month traditionally)
- January: 2.43 inches of rain (Dry, dusty, and blue skies)
Swimming in the Gulf: Is the Water Actually Warm?
You’d think the water temperature would mirror the air, but the Gulf of Mexico has its own personality.
If you're visiting in January, the water is around 64°F to 66°F. Honestly? That's too cold for most locals. You'll see the tourists from Minnesota jumping in while the Floridians are wrapped in towels on the sand.
By August, the Gulf turns into a bathtub, hitting 87°F. In fact, in recent years, we've seen localized "hot tub" spikes where shallow waters near the shore have hit the mid-90s. While it’s great for wading, it’s not exactly refreshing when you’re trying to escape the sun.

Hurricane Season and Temperature Spikes
We have to talk about the elephant in the room. Hurricane season runs from June 1 to November 30. While the storms are the main concern, the temperatures during this window are the most brutal of the year.
When a tropical system is nearby but not directly over us, it often "sucks" the moisture out of the air or blocks the sea breeze, leading to some of the hottest, most stagnant days on record.
Practical Tips for Your Visit
Don't trust the 7-day forecast too far out. Florida weather is chaotic.
1. The "Floridian Layer"
Even if the high is 80°F, every restaurant, mall, and movie theater in Fort Myers is air-conditioned to roughly the temperature of a meat locker. Bring a light hoodie. You'll thank me when you're eating dinner.

2. Sunscreen is not optional
Because Fort Myers is further south than most people realize, the UV index is high even on "cool" days. A 70-degree day in February can still give you a blistering sunburn in 30 minutes if you aren't careful.
3. Morning is King
In the summer, if you want to do anything outdoors—golfing, hiking at Six Mile Cypress Slough, or hitting the beach—finish it by 11:00 AM. After that, the heat becomes a physical weight.
Actionable Steps for Your Trip
- Check the Dew Point: If you're looking at the weather app, ignore the "Temperature" and look at the "Dew Point." If it's over 70, you're going to be sweaty. If it's under 60, it's a perfect day.
- Download a Radar App: Since rain moves in fast, "MyRadar" or similar apps are better than standard weather apps. You can see the cells forming in real-time.
- Plan Around the Cold Fronts: If you're coming in winter, keep an eye on the "Thursday dip." Pack one pair of long pants and a jacket just in case the mercury drops into the 40s.
Knowing what's the temperature in Fort Myers Florida is about more than just a number; it’s about timing the humidity and the sea breeze. Plan for the sun, prepare for the 4:00 PM rain, and always keep a sweater in the car for the AC.
