Right now, if you're standing on the Strip and looking up at the neon, you’re probably feeling a bit of a nip in the air that wasn't there a few hours ago. Honestly, people come here expecting 100-degree heat year-round, but January has a way of reminding you that Las Vegas is, first and foremost, a high-desert environment.
As of Sunday evening, January 18, 2026, the current temperature in Las Vegas is sitting at 57°F.
It’s one of those classic desert nights where the sky is clear with periodic clouds, and the air feels incredibly still—the wind is basically nonexistent right now, clocked at 0 mph coming from the west. If you’re heading out to dinner or catching a show, you’ve definitely reached the "jacket required" portion of the evening.
Why the Current Temperature in Las Vegas Feels Different Tonight
There’s a specific kind of chill that hits the Mojave once the sun goes down. Even though 57°F might sound like a mild spring day in Chicago or New York, the 29% humidity makes it feel sharper. There is no moisture in the air to hold onto the day's heat. Earlier today, we saw a high of 63°F, but that warmth is escaping into the atmosphere fast.
By the time the late-night crowds are spilling out of the casinos, we’re looking at a low of 42°F.
It’s kind of wild when you think about the swing. You can go from a comfortable 63°F mostly cloudy afternoon to a 42°F night in just a few hours. That’s a 21-degree drop. If you aren't dressed in layers, the walk between Caesars Palace and the Bellagio fountains is going to feel a lot longer than it actually is.
Desert Dynamics: Humidity and the UV Factor
Earlier today, the UV index was at a measly 1. Basically, you weren't getting a tan even if you tried. Tonight, it’s 0. While that sounds obvious for nighttime, it matters because the sun isn't there to provide that radiant heat that usually makes Vegas feel so intense.
The precipitation chance is holding steady at 0% for the night, so you don't have to worry about rain ruining your hair or your suede shoes. It’s just cold, dry, and crisp.
Packing for Las Vegas in January
Most travelers make the mistake of packing for the "Vegas" they see in movies—pool parties, bikinis, and short sleeves. If you do that this week, you’re going to end up buying an overpriced souvenir hoodie at a gift shop.
- The Layering Rule: Since the high today hit 63°F but we’re heading toward 42°F, you need a light jacket for the day and a heavier coat or a solid sweater for the night.
- Moisturize Everything: With humidity at 29%, your skin will feel like parchment paper. The desert air literally sucks the moisture out of you.
- Footwear Matters: It’s a walking city. Even when the current temperature in Las Vegas is a manageable 57°F, the wind can whip through the canyons created by the massive hotels, making it feel several degrees colder.
What to Expect for Tomorrow
Looking ahead to Monday, January 19, things are going to stay pretty consistent. We’re expecting a high near 65°F with plenty of sunshine. It’s perfect walking weather—not too hot, not too cold. Just remember that the 40s will return as soon as the sun dips behind the Spring Mountains.

The "winter sun" in Nevada is actually some of the best weather the city sees all year. You get the bright blue skies without the oppressive 115-degree heat that makes the pavement melt in July. It’s a different vibe, sure, but for anyone who actually wants to see the sights without breaking a sweat, this 57°F evening is actually pretty ideal.
Actionable Next Steps:
If you are currently in Las Vegas or arriving tonight, check the local sensors at McCarran (Harry Reid International) for real-time wind gusts, as the "feels like" temperature can drop significantly if the breeze picks up. Ensure you have a hydration plan; even at 57°F, the low humidity causes rapid dehydration that most visitors mistake for a "Vegas hangover."
