If you're planning a trip to the Sunshine State, you've probably heard the warnings. "It’s too hot." "It’s hurricane season." "The humidity will melt your face off."
Honestly? They aren't exactly lying. But they aren't giving you the full picture either.
Weather in Florida for September is a bizarre, beautiful, and occasionally frustrating contradiction. It’s a month where the air feels like a warm, wet blanket, yet the theme park lines are suddenly shorter. It's the peak of the Atlantic hurricane season, but it's also when you can find some of the best travel deals of the year.
Basically, it's high-stakes vacationing.
If you want the "chamber of commerce" version, look elsewhere. If you want to know what it’s actually like to stand in Orlando or Miami during the ninth month of the year, let’s get into the weeds of the data and the reality on the ground.
The Brutal Truth About the Temperature
Let's talk numbers. Real ones.
In September, most of Florida is still effectively in the middle of summer. Northern cities like Jacksonville or Tallahassee might see a tiny dip toward the end of the month, but for the most part, you’re looking at average highs between 88°F and 91°F.
But those numbers are liars.
They don't account for the "feels like" temperature, which is what actually matters when you’re walking from your car to a restaurant. Because the dew points remain stubbornly high—often staying above 72°F—the heat index regularly climbs into the triple digits. It’s not uncommon for a 90-degree day in Tampa to feel like 105°F.
You will sweat. A lot.
Southern Florida, particularly Miami and the Keys, stays the warmest. In September 2024, Key West and West Palm Beach actually recorded their warmest September on record. We're talking mean temperatures around 83°F to 84°F, which doesn't sound bad until you realize the "lows" at night barely crack 78°F. There is no "cooling off" period.

Why Everyone Obsesses Over the 2:00 PM Storm
If you've never been to Florida in the late summer, the rain pattern is weird.
It’s not like a gray, drizzly day in Seattle. It’s more like a pressure cooker that finally explodes.
Most days start out blindingly sunny. By noon, the clouds start stacking up like towers of mashed potatoes. Then, usually between 2:00 PM and 5:00 PM, the sky opens up. It’s a deluge. Massive, heavy drops that turn parking lots into rivers in minutes.
The good news? It usually lasts about 45 minutes.
Then the sun comes back out, and the water on the asphalt evaporates, turning the entire state into a giant sauna. This is the "daily thunderstorm" cycle. However, September can be unpredictable. In 2025, for instance, Tampa had its driest September in 136 years, while Fort Lauderdale had its third wettest. It’s a literal roll of the atmospheric dice.
Rainfall Variability by City
- Miami: Expect a lot. Average rainfall is often over 8 inches for the month.
- Orlando: Usually around 6 inches, though Hurricane Ian once dumped way more than that in a single day.
- The Panhandle: Places like Pensacola often see a slight decrease in rain compared to the swampy peninsula, but they are more susceptible to early-fall cold fronts that can stall out and cause flooding.
Navigation the Peak of Hurricane Season
We have to talk about the elephant in the room. September 10th.
According to the National Hurricane Center, September 10th is the statistical peak of the Atlantic hurricane season. This is the date when the ocean is at its warmest and the wind conditions are most favorable for a storm to spin up.
Does this mean a hurricane will hit during your trip? Probably not. But the odds are higher now than at any other time of the year.
Think about recent history. Hurricane Ian (2022), Hurricane Irma (2017), and Hurricane Helene (2024) were all September events. When these storms hit, the weather in Florida for September goes from "sticky" to "catastrophic" very quickly.
If you are traveling during this window, you absolutely must have travel insurance that covers "named storms." Without it, you’re just gambling with your deposit. Keep a close eye on the NHC forecasts. If a cone of uncertainty starts pointing at your hotel, it’s time to activate your "Plan B."
The "Secret" Perks of September Weather
It sounds miserable so far, right? So why do people come?
Because the crowds vanish.
Once Labor Day passes and the kids go back to school, Florida's tourism enters a "shoulder season." The weather is still summer, but the vibe is much more relaxed.
- Lower Prices: Hotels in the Keys or Gulf Coast that charge $500 a night in March might be $220 in September.
- The Water is Perfect: The Gulf of Mexico and the Atlantic are at their warmest. We're talking 85°F to 87°F. It’s like swimming in a heated pool.
- Theme Park Hacks: If you can handle the afternoon rain, you can often walk onto rides at Disney or Universal that usually have two-hour waits. Just bring a poncho and keep moving while everyone else runs for cover.
How to Actually Survive This
If you’re going to brave the weather in Florida for September, you need a strategy. Don't just wing it.
First, flip your schedule. Do your outdoor activities between 8:00 AM and 11:00 AM. After lunch, find something indoors—a museum, a mall, or a long nap in a room with the AC cranked to "Arctic."
Second, the "Florida Uniform" is real. Forget jeans. Forget heavy cotton. You want moisture-wicking fabrics and loose fits. If you're walking a lot, bring two pairs of shoes. One will inevitably get soaked in a 4:00 PM downpour, and it won't dry by the next morning because the humidity is too high.

Third, hydration isn't a suggestion; it's a requirement. The Florida Department of Health constantly warns about heat exhaustion in September. If you aren't drinking twice as much water as you think you need, you’re doing it wrong.
Actionable Insights for Your Trip
- Check the "Dew Point" over the "Temperature": If the dew point is over 70°F, it's going to be oppressive regardless of the thermometer.
- Download a Radar App: Don't trust the "percent chance of rain" on your iPhone weather app. Use something like MyRadar to see exactly where the storm cells are moving in real-time.
- Book Refundable Everything: Between hurricanes and sudden flight delays, flexibility is your best friend in September.
- Pack "The Big Three": A high-quality umbrella (not a cheap $5 one that will flip inside out), electrolyte powder, and a portable neck fan.
September in Florida is a test of endurance, but for those who know how to play the game, it’s a chance to see the state at its most raw and quiet. Just don't say I didn't warn you about the humidity.
To prepare your gear for the trip, you should look into moisture-wicking clothing brands and high-UPF rated sunshirts that can keep you cool without requiring constant sunscreen reapplication. It's also worth verifying your hotel's hurricane cancellation policy specifically for "Level 3" storm warnings before you lock in a non-refundable rate.
