The smell is unmistakable. It’s that sharp, metallic tang of incinerated brush mixed with the heavy, sweet scent of eucalyptus going up in flames. If you live in Southern California, you know that smell too well. Right now, the hills of Los Angeles are burning, and honestly, it feels like a movie we’ve all seen a hundred times before, yet the ending never gets any easier to watch. It’s a terrifying, beautiful, and deeply frustrating cycle.
Fire is part of the DNA here.
But things are changing. It’s not just "fire season" anymore; it’s basically just "the way things are." We are seeing fires that behave in ways even veteran CAL FIRE captains find baffling. The physics of it is wild. You have these massive plumes of smoke creating their own weather systems, known as pyrocumulonimbus clouds, which can actually spit out lightning and start more fires miles away from the original front.
Why the hills of Los Angeles are burning more intensely now
The old logic was simple: we had a rainy winter, the hills got green, then they dried out in the summer, and by October, the Santa Ana winds turned the place into a tinderbox. That’s still true, but the math has shifted. We’re dealing with a "legacy of suppression." For about a century, the goal was to put out every single spark immediately. It sounds like a good idea, right? Keep the fires away from the houses.
The problem is that by stopping every small, natural fire, we’ve allowed a massive amount of "fuel load" to build up. Those hills are packed with decades of dead scrub, dried-out invasive grasses, and oily chaparral. When it finally goes, it doesn't just burn. It explodes.
Scientists like Dr. Alexandra Syphard have pointed out that human expansion into the Wildland-Urban Interface (WUI) is the real catalyst. We keep building deeper into the canyons. We put multi-million dollar Mediterranean villas in places that are ecologically designed to burn every 30 to 50 years. When the hills of Los Angeles are burning, it’s often because a power line flickered, a catalytic converter sparked on dry grass, or someone was using a lawnmower at 2:00 PM on a 100-degree day. Over 90% of these fires are started by us.
The Santa Ana Factor
You can't talk about LA fires without talking about the winds. These aren't your typical breezes. They are high-pressure systems from the Great Basin that get squeezed through the mountain passes. As the air drops in elevation, it compresses, heats up, and loses every drop of moisture. By the time it hits the San Fernando Valley or the Malibu coast, the humidity is in the single digits.

Wood becomes as dry as kiln-dried lumber. At that point, a single ember can travel a mile through the air, land on a palm tree or a shingle roof, and start a new inferno. It’s called "spotting," and it’s why firefighters struggle to get a handle on these blazes once the wind picks up. It’s like trying to stop a flood with a toothpick.
The ecological toll nobody talks about
Everyone focuses on the houses. It makes sense; seeing a home in Bel Air or Pacific Palisades engulfed in flames is a visceral image. But the hills themselves are suffering in ways that might be permanent.
Chaparral is tough. It’s evolved to handle fire. But it isn't meant to burn every three years. When the frequency of fire increases—what ecologists call "type conversion"—the native shrubs don't have time to drop seeds or regrow. They get replaced by invasive, non-native grasses. These grasses dry out faster, burn easier, and offer zero soil stability.
Then the rains come.
Without the deep roots of native sumac and manzanita, the hillsides just give up. You get the mudslides. We saw this vividly after the Thomas Fire and the subsequent Montecito debris flows. The land literally turns into liquid. It’s a secondary disaster that often claims more lives than the flames themselves.
The air we breathe
If you’re sitting in an office in Santa Monica or a coffee shop in Silver Lake while the hills of Los Angeles are burning, you’re breathing in more than just wood smoke. You’re breathing in vaporized plastic, lead paint, insulation, and whatever else was in the houses that burned.

The South Coast Air Quality Management District (AQMD) constantly warns about PM2.5—tiny particles that are small enough to enter your bloodstream through your lungs. It’s not just an "annoyance" or a reason to wash your car. It’s a legitimate public health crisis that lingers long after the visible smoke has cleared out toward the Pacific.
Is there a "new normal" for Los Angeles?
People love that phrase, "the new normal." Honestly, it’s a bit of a cop-out. It implies we’ve reached a new plateau and things will stay this way. But the reality is more of a "sliding scale of chaos." Climate change has extended the burn window. We now have 80-degree days in January with offshore winds.
The Getty Fire in 2019 was a wake-up call for many because it hit an area that felt "safe." It showed that no amount of money or prestige can fully insulate you from the geography of California. If you live near a canyon, you are part of the ecosystem.
Modern firefighting technology is incredible, though. We have the "Quick Reaction Force," which includes massive Helitankers like the CH-47 Chinooks that can drop 3,000 gallons of water at a time—and they can fly at night. This was a game-changer. Before, pilots had to grounded at sunset for safety. Now, they can hit the fire while the humidity is slightly higher and the winds are (hopefully) calmer.
Defensive space is not optional
If you live in the hills, you've probably received those notices from the LAFD about brush clearance. It’s easy to ignore them or complain about the cost of hiring a crew. But that 100 feet of "defensible space" is usually the only thing that determines if a house survives or turns into a pile of ash.
It’s not just about cutting grass. It’s about:

- Clearing out the "ladder fuels" (low branches that allow fire to climb into the canopy).
- Cleaning the gutters (dry leaves in a gutter are basically a fuse for your roof).
- Replacing attic vents with fine mesh that stops embers from getting sucked into your house.
What we get wrong about forest management
You’ll often hear people say, "We just need to rake the forests." Aside from being a weirdly simplistic take, it ignores that most of LA isn't "forest." It’s shrubland. You can’t "thin" chaparral the way you thin a pine forest in the Sierras.
The real conversation should be about "prescribed burns." This is where we intentionally set fires under perfect conditions to clear out the undergrowth. Indigenous tribes in California did this for millennia. We are finally starting to realize they had it right. But doing a prescribed burn in a place as densely populated as Los Angeles is a legal and logistical nightmare. One shift in the wind and you’ve smoked out five million people or, worse, burned down a neighborhood.
The risk is high, but the cost of doing nothing is higher.
Moving forward in a burning landscape
Living in Los Angeles means accepting a certain level of environmental anxiety. We have the earthquakes, the droughts, and the fires. But the fires are the only ones that feel preventable yet inevitable at the same time.
We have to stop looking at the hills of Los Angeles are burning as a freak accident. It’s a systemic issue tied to how we build, how we manage land, and how we handle the warming climate. The firefighters are heroes, but they can't be our only line of defense.
If you are a resident, or even if you’re just visiting, the responsibility is shared. We have to be smarter about the WUI. We have to support policies that prioritize retrofitting older homes in high-fire-risk zones. And frankly, we have to get used to the idea that some days, the air will be orange, and we’ll have to stay inside.
Actionable steps for the "Fire Season"
You shouldn't wait until you see smoke on the horizon to get your life in order. The speed of these fires is genuinely hard to wrap your head around until you’re in one.
- The Go-Bag is a cliché for a reason. Put your birth certificates, passports, and a few days of meds in one place. If the cops knock on your door at 3:00 AM, you won't have time to look for your social security card.
- Hardening your home matters. If you have the budget, look into ignition-resistant siding or boxed-in eaves. If you don't, just keep the 5-foot zone around your foundation completely clear of anything flammable—no mulch, no wooden fences touching the house, no bushes.
- Register for alerts. In LA, use NotifyLA. It’s the official way the city sends out evacuation orders. Don't rely on Twitter (or X) or the news to tell you when it’s time to leave. By the time it’s on the news, the roads might already be jammed.
- Think about your pets. Have crates ready. Animals get stressed and hide when they smell smoke. If you have to spend twenty minutes fishing a cat out from under a bed, you’re losing precious time.
- Check your insurance. This is the boring part, but many people in the hills are being dropped by private insurers and moved to the California FAIR Plan. Know what your policy actually covers. Does it cover "replacement cost" or just "actual cash value"? There is a massive difference when you're trying to rebuild in LA's insane construction market.
The hills will burn again. It's the price of admission for living in one of the most beautiful, rugged, and complex urban environments on earth. The goal isn't to live in fear, but to live with a healthy respect for the landscape. We are guests in these canyons, and the chaparral always remembers who was there first.
