Florida is basically a giant sponge. Most people look at the River of Grass and see nothing but endless water, sawgrass, and maybe a grumpy alligator or two. So, when you hear about wildfires in the Everglades, it sounds like a glitch in the simulation. How does a literal swamp catch fire? It feels wrong. Like a kitchen sink bursting into flames while the faucet is running. But honestly, fire is just as much a part of this landscape as the water is. Without it, the whole ecosystem would basically choke to death on its own success.
The Everglades is a fire-adapted landscape. It's weird to think about, but the plants there have evolved to expect a good scorching every few years. If you've ever driven down I-75 (Alligator Alley) and seen those massive plumes of white smoke billowing over the horizon, you’re looking at a biological reset button. It’s messy, it smells like a wet campfire for three counties, and it’s absolutely vital.
The Chemistry of a Burning Swamp
Lightning is the primary culprit. Florida is the lightning capital of the country, and when those summer afternoon storms roll in, they throw sparks into tinder-dry sawgrass. This is where it gets interesting. Wildfires in the Everglades don't usually behave like the massive forest fires you see in California. In the West, you have "crown fires" that leap from treetop to treetop, obliterating everything. In the Glades, it’s mostly a "surface fire." The fire moves fast, zipping across the top of the water or the damp muck, fueled by the volatile oils in the sawgrass.
Wait. Water?
Yes. Sawgrass can burn even when it’s standing in several inches of water. The dead outer leaves of the grass are incredibly dry and act like a fuse. The fire roars through, clearing out the "thatch"—that layer of dead plant material that piles up over time. If that thatch isn't cleared, it clogs the sloughs. It stops the water from flowing south. It turns a vibrant, pulsing wetland into a stagnant, overgrown mess. By burning it off, the fire releases nutrients like phosphorus back into the system, though too much phosphorus is actually a problem for the Glades (thanks, sugar farming), but that's a whole different headache.

When the Ground Itself Catches Fire
The real nightmare isn't the grass burning. It's the peat.
Peat is basically thousands of years of compressed, decayed plant matter. It’s the "soil" of the Everglades. During a severe drought, the water table drops so low that this organic muck dries out. When a wildfire hits dry peat, it doesn't just flame up and move on. It smolders. It burns underground for weeks, sometimes months. These "muck fires" are a disaster. They destroy the literal foundation of the ecosystem. They create deep holes in the limestone bedrock, which is cool for making new "gator holes," but if the fire burns too deep, it kills the roots of the hardwood hammocks—those little islands of trees like mahogany and coco plum. Once a hammock is gone, it’s gone for a lifetime.
Why 2026 Feels Different for Florida Fire Seasons
We’ve seen some strange patterns lately. Meteorologists at the National Hurricane Center and the Florida Forest Service have been tracking how shifting rainfall patterns—likely tied to those stubborn El Niño/La Niña cycles—are messing with the traditional "dry season." Usually, the risk for wildfires in the Everglades peaks between March and May. That’s when the winter rains have vanished, but the summer thunderstorms haven't kicked in yet.
But things are getting twitchy. We’re seeing "flash droughts" where the humidity drops off a cliff in February. If you’re planning a trip to the Everglades National Park or Big Cypress National Preserve, you’ve got to keep an eye on the KBDI (Keetch-Byram Drought Index). It’s a 0-800 scale that tells you how thirsty the ground is. If that number starts creeping toward 600, the Park Service starts getting very nervous. They’ll shut down backcountry camping faster than you can say "prescribed burn."

Speaking of prescribed burns, they are the unsung heroes here. The Florida Forest Service and the National Park Service don't just wait for lightning. They start fires on purpose. It’s called "fuel reduction." By burning sections of the park under controlled conditions—low wind, right humidity—they create "black lines" or firebreaks. This way, when a real, unplanned wildfire kicks off, it hits a patch of ground that’s already been burned and has no "fuel" left. It starves the fire. It’s basically fighting fire with fire, quite literally.
The Human Problem: Smoke and I-75
Let’s talk about the smoke. It’s the part that actually affects people living in Miami, Fort Lauderdale, and Naples. Wildfires in the Everglades produce a very specific kind of thick, acrid smoke because of the high organic content in the plants.
- Superfog: This is a real, terrifying thing. It’s what happens when smoke mixes with heavy morning fog. It can drop visibility on the Florida Turnpike or I-75 to literally zero inches.
- Respiratory issues: If you have asthma and live in South Florida, fire season is your enemy. The particulate matter (PM2.5) from a large Everglades fire can blanket the coast for days.
- Travel delays: It’s not uncommon for the Florida Highway Patrol to shut down major arteries across the state because the smoke makes driving a death trap.
If you’re visiting, you might see "Smoke Ahead" signs. Don’t ignore them. Florida drivers are already aggressive; add a wall of grey haze into the mix and things get ugly fast.
What Most People Get Wrong
People think fire is a tragedy for wildlife. It isn't. Most animals in the Glades are total pros at dealing with it.

Gators just sink deeper into their holes. Birds fly away. Snakes and small mammals duck into limestone crevices or holes in the ground. In fact, many species thrive after a fire. The fresh green shoots that pop up a week after a burn are incredibly high in nutrients. Deer and marsh rabbits flock to these "blackened" areas to feast on the new growth. It’s like a giant buffet opening up after a long winter.
The only real losers are the invasive species. The Everglades is currently losing a war against Burmese pythons and Brazilian pepper trees. Fire helps—slightly. Brazilian pepper is somewhat fire-resistant, but a good, hot fire can knock it back and give the native sawgrass a fighting chance to reclaim its territory.
How to Stay Safe and Informed
If you’re heading out to the River of Grass, you need to be smart. You’re entering a wilderness that is actively trying to manage its own health, and sometimes that involves 20-foot flames.
First, check the Air Quality Index (AQI). If there’s a major fire in the Big Cypress area, the air in Homestead or even Miami might be "Code Orange." Not the best time for a long hike. Second, follow the official social media accounts for Everglades National Park. They are surprisingly good at posting real-time updates on trail closures.
Don't be the person who starts a fire. Most wildfires in the Everglades are natural, but a significant chunk are still caused by human stupidity—discarded cigarettes, hot mufflers on dry grass, or illegal campfires. In a place this dry, a single spark can cost the state millions in suppression efforts and destroy habitats that took centuries to form.
Actionable Steps for Your Visit
- Monitor the KBDI: Before booking an airboat tour or a "slough sough" (swamp walk), check the drought index for Miami-Dade or Collier County. If it's over 500, expect campfire bans.
- Download the FEMA App: It gives you real-time weather and fire alerts based on your GPS location.
- Respect the Closures: If a boardwalk is closed due to "fire activity," stay off it. Even if you don't see flames, the smoke can be toxic, and fire moves faster than you think in a wind-driven sawgrass prairie.
- Support Local Conservation: Groups like the Everglades Foundation work on water restoration. More water in the Glades means fewer destructive muck fires and a healthier cycle for the natural fires the land actually needs.
The Everglades is a paradox. It’s a world of water that needs fire to survive. It’s a place that looks eternal but changes by the hour. Next time you see that smoke on the horizon, don't just see a disaster. See a forest—or a swamp—taking a deep, cleansing breath. Just maybe keep your windows rolled up while you're driving through it.
