Pack a parka. Also, bring a swimsuit.
That sounds like a joke, but if you’ve spent any time on the Strip when the calendar flips to March, you know the Las Vegas temperature March brings is basically a meteorological identity crisis. One minute you’re sweating through a linen shirt at a pool party at Encore Beach Club, and six hours later, you’re shivering in a windbreaker because a cold front just screamed down from the Spring Mountains. It’s chaotic. It’s lovely. It’s deeply confusing for first-timers who assume "Nevada" just means "hot" all the time.
Honestly, March is probably the most requested month for Vegas travel for a reason. The blistering 115-degree heat of July is months away. The bone-chilling desert nights of January are fading. But there’s a catch. You aren’t just dealing with a single temperature; you’re dealing with a 30-degree swing every single day.
The Reality of the Las Vegas Temperature March Numbers
Let’s look at the hard data from the National Weather Service. On average, you’re looking at afternoon highs of around 70°F to 72°F. That sounds perfect, right? It is. But averages are liars.
In early March, you might see highs struggling to hit 65°F. By the time the end of the month rolls around and March Madness is in full swing at the sportsbooks, it’s not uncommon to see the mercury tickle 80°F or even 85°F. But the real kicker is the "diurnal swing." Because the desert air is so dry, it doesn't hold onto heat. Once the sun dips behind the Red Rock canyons, the temperature craters. Those 70-degree afternoons become 45-degree nights faster than you can lose a twenty on a Buffalo Gold machine.
Wind: The Silent Party Pooper
If you ask a local what they hate most about the Las Vegas temperature March provides, they won't say the cold. They’ll say the wind.
March is notoriously the windiest month in Southern Nevada. We get these massive pressure shifts. The Mojave Desert acts like a giant vacuum, pulling in air from the Pacific and the Great Basin. You’ll be walking across a pedestrian bridge over Las Vegas Boulevard, and suddenly, a 35-mph gust hits you. It makes a 68-degree day feel like 55. If you’re planning on a high-limit rooftop lounge experience or even just a walk to the Sphere, the wind chill is a legitimate factor you have to account for.
Pool Season vs. Reality
Every year, the big resorts like Caesars Palace, MGM Grand, and Wynn try to open their pool decks by early March. It’s a gamble.
Is the water heated? Usually, yes. Most major Strip properties keep their main pools at a balmy 80 degrees. But getting out of the water is the problem. If the air temperature is 66 degrees and there’s a breeze, you aren’t "relaxing"—you’re surviving.
I’ve seen people huddled under towels like they’re at an Arctic base camp, desperately trying to get a tan because they paid $400 for a cabana. If you want a "true" pool day, aim for the last ten days of the month. Before that, it’s hit or miss. You’ll see the sun, and it’ll be bright—Vegas gets about 12 hours of daylight in March—but the "heat" part is subjective.
What About the Rain?
Statistically, March isn't the wettest month—that’s usually February or even the monsoon season in July—but we still get the occasional Pacific storm that manages to hop over the Sierra Nevada mountains.
When it rains in Vegas, the city forgets how to function. The roads get slick because of all the oil buildup that hasn't been washed away, and the temperature drops instantly. If you see clouds over the mountains to the west, expect a sharp cooling trend within the hour. It’s not the "stay inside all day" kind of rain you get in Seattle, but it’s enough to ruin a round of golf at Shadow Creek.
Dressing for the Vegas Spring Chaos
How do you dress for a 25-degree variance?
Layers. It's a cliché because it works.
If you’re heading out for the day, wear a light base layer. A t-shirt is fine. But you must have a denim jacket, a light puffer, or a heavy hoodie in tow. If you leave your hotel room at 2:00 PM and don't plan on returning until after dinner, you will regret being in short sleeves by 7:00 PM.
Also, don't forget the humidity—or lack thereof. March humidity in Vegas usually hovers around 20% to 25%. That’s dry. Your skin will crack, your eyes will itch, and you’ll feel colder than the thermometer says because your sweat evaporates instantly, cooling your skin down. Drink more water than you think you need. Staying hydrated actually helps your body regulate its temperature better against those desert swings.
Why the Location Matters: Strip vs. Red Rock
The Las Vegas temperature March creates is not uniform across the valley.
The Strip is a "heat island." All that concrete, the neon lights, and the thousands of idling Ubers keep the immediate area a few degrees warmer than the outskirts. If you’re staying at the South Point or heading out to Summerlin, expect it to be 3 to 5 degrees cooler.
Heading to Red Rock Canyon for a hike? It’s higher elevation. For every 1,000 feet you climb, you lose about 3 to 5 degrees. If it’s a beautiful 72 on the Strip, it might be a crisp 62 at the trailhead. That’s perfect hiking weather, honestly. Just don't go up to Mt. Charleston expecting spring; there’s often still snow on the ground in March, and temperatures can still be near freezing.
The "March Madness" Effect
Beyond the weather, the atmosphere in the city changes. March is high season. Between the NCAA tournament and various conventions, the sheer volume of people changes how "warm" the city feels. Crowded casinos stay warmer. Walking the Strip involves more body heat from the throngs of tourists.

But it also means the "comfortable" spots—the outdoor patios at Beer Park or the terrace at Mon Ami Gabi—are in high demand. If the weather hits that 75-degree "sweet spot," every outdoor seat in the city will be gone by noon.
Comparing March to the Rest of the Year
People often ask if they should come in March or April.
April is more consistent. April is "safe." By April, the lows rarely dip below 50, and the highs are firmly in the 80s.
March is for the adventurous. It’s for the people who like the crisp morning air and the ability to walk a mile without needing a shower afterward. It’s arguably the best time for "active" Vegas—walking the entire length of the Strip, checking out the Fremont Street Experience, or doing the Hoover Dam tour. You won't get heat exhaustion, which is a very real risk just eight weeks later.
Actionable Steps for Your March Vegas Trip
Don't just look at the 10-day forecast and assume it’s right. Those forecasts struggle with the Mojave’s volatility.

- Check the Wind Forecast: Use an app like Windy or look at the "Wind Speed" line on Weather.com. Anything over 15 mph means your pool day is probably going to be chilly.
- Pack "The Transition Piece": A high-quality flannel or a light bomber jacket is the MVP of a March Vegas wardrobe. It looks good enough for a casual dinner but handles the 50-degree evening walk back to the hotel.
- Book Heated Pools: If you’re a swimmer, call the concierge. Ask specifically, "Is the pool heated to at least 80 degrees right now?" Some smaller boutiques don't bother heating them, and a 60-degree pool is basically a polar plunge.
- Moisturize Early: Start using heavy lotion and lip balm the day you arrive. The March air will wick the moisture out of your skin before you even realize you're dry.
- Plan Indoor Alternatives: If a "North Wind" kicks up, have a backup plan that doesn't involve being outside. This is the perfect time for the Mob Museum, the Neon Museum (which is outdoors but manageable), or a long session at the poker tables.
The Las Vegas temperature March offers is a gateway. It’s the bridge between the dormant winter and the oppressive summer. If you respect the sun and prepare for the wind, it’s easily the best time to see the city. Just don't be the person walking around in a bikini when the sun goes down and the temperature hits 48 degrees. You’ll look like a rookie, and you’ll feel even worse.
