You’re standing on the Strip in July. The air doesn't just feel hot; it feels heavy, like a physical weight pressing against your skin. You look at one of those big digital bank thermometers and it screams 114°F. Your first thought? "It’s a dry heat."
Honestly, that’s the biggest lie we tell ourselves about the desert. Dry or not, triple digits are a beast. If you're planning a trip to Sin City, understanding what is temperature in las vegas isn't just about packing the right shirt. It’s about survival, or at least, not spending your entire vacation nursing a heat-induced headache in a dark hotel room.
Vegas is a land of extremes. One month you’re melting; a few months later, you’re shivering in a North Face jacket while waiting for the Bellagio fountains to dance. People think of Nevada as an eternal summer, but the high desert has a wicked sense of humor.
The Reality of the "Dry Heat" Myth
We’ve all heard it. "At least it's not humid like Florida!" True, Las Vegas doesn't have that "breathing through a wet blanket" feel. But the dry air is a double-edged sword. Because the humidity often hovers around 10% to 15% in the summer, your sweat evaporates instantly.
You don't feel "sticky," so you don't realize how much water you’re actually losing. In 2025, Las Vegas saw 77 days where the mercury hit 100°F or higher. That’s over two months of oven-like conditions. Even in June 2024, record highs reached 112°F by mid-month. When the air is that dry, your skin can actually start to feel tight and itchy within minutes of walking outside.

The Winter Chill (December to February)
Don't let the palm trees fool you. Winter in Vegas is legit cold. In December and January, the average high is around 57°F or 58°F. That sounds mild until the sun goes down. Once that desert sun dips behind the Spring Mountains, the temperature crashes into the high 30s.
I’ve seen tourists walking the Strip in January wearing shorts and flip-flops because they saw "Nevada" on the map. They look miserable. Honestly, you need a coat. In January 2025, it actually dropped to 29°F. If you're coming in the winter, think layers.
The Perfection of Spring and Fall
This is when Vegas shines. March and April are spectacular, with highs ranging from 70°F to 80°F. It’s pool season, but you won't feel like you're being slow-cooked.
October is arguably the best month of the year. The average high is 81°F, and the air starts to get that crisp, autumn feel. It’s the peak time for hiking at Red Rock Canyon or exploring Valley of Fire without worrying about heatstroke.
The Summer Blast (June to August)
This is the danger zone. July is the hottest month, with an average high of 104°F, though 110°F is a regular occurrence. In 2021, the city hit an all-time record of 117°F.

- June: Hits 100°F regularly. It’s the windiest month, too, which feels like standing behind a jet engine.
- July: The peak. Highs of 105°F are the "normal."
- August: Still brutal, but this is when the "monsoon" season kicks in. You might get sudden, violent thunderstorms that drop the temp 20 degrees in ten minutes, only to make it humid and gross an hour later.
Why the Wind Changes Everything
People forget about the wind. Las Vegas is basically a giant bowl surrounded by mountains. In the spring, especially April and May, the wind can be relentless. We’re talking sustained speeds of 15 to 20 mph with gusts that can knock a drink out of your hand.
In the summer, the wind doesn't cool you down. It’s like a convection oven. If it’s 110°F and the wind is blowing at 20 mph, it’s just pushing more heat into your body. It's weirdly exhausting.
Survival Tips from a Local Perspective
If you have to be here when it’s 110°F, you need a strategy. You can't just wing it.
First, the "Resort Walk" is your best friend. Most of the major hotels on the Strip are connected by bridges, trams, or internal walkways. You can get from Park MGM to the Bellagio almost entirely in air conditioning if you know the routes.
Second, water isn't enough. You need electrolytes. The dry air sucks the salt right out of you. If you’re drinking nothing but plain water while walking the Strip, you’ll end up bloated and still feeling "off." Grab a Gatorade or some Liquid IV packets.

Third, watch your feet. The pavement in Vegas can reach 160°F in the summer. If you’re wearing thin-soled sandals, your feet are going to cook. More importantly, if you have a dog, keep them off the asphalt. People forget and their pups end up with burned paws. It’s heartbreaking.
The Mount Charleston Escape
When the Strip is 115°F, there’s a secret escape. Mount Charleston is only about 45 minutes away, and because it’s at a much higher elevation (over 7,500 feet), it’s usually 20 to 25 degrees cooler.
Locals head up there to hike or just to breathe air that doesn't feel like it came out of a hairdryer. It’s a literal lifesaver during a July heatwave.
Actionable Takeaways for Your Trip
Stop checking the "average" and start looking at the "lows." The gap between day and night in the desert is huge.
- For Summer Trips: Only plan outdoor activities (like the Neon Museum or walking the Strip) after 8:00 PM or before 9:00 AM.
- For Winter Trips: Bring a medium-weight jacket. The wind off the desert at night is biting.
- The Hydration Rule: Drink 8 ounces of water for every alcoholic beverage. The "Vegas Flu" is usually just severe dehydration masquerading as a hangover.
- Skin Care: Sunscreen is non-negotiable, even in February. The UV index here is high because of the elevation and the lack of cloud cover.
Plan your wardrobe around the "15-degree rule." If the forecast says 75°F, it’ll feel like 90°F in the direct sun and 60°F in the shade or inside a casino where the AC is set to "Arctic." Layers are the only way to win the Vegas weather game.
Now that you know the score, check the specific 10-day forecast for your dates. If you see anything over 105°F, move your outdoor dinner reservations to an indoor spot. You’ll thank yourself when you aren't sweating through your nice clothes before the appetizers arrive.
