So, you’re looking at the weather 10 day las vegas nv and thinking about whether to pack that heavy coat or just a light hoodie. Honestly, the desert is a bit of a trickster in January. Most people see "Las Vegas" and "Desert" and assume it's going to be warm enough for pool time year-round. It’s not. Not even close.
Right now, as of Sunday, January 18, 2026, Vegas is sitting in that weird winter transition where the sun feels amazing but the shade feels like a freezer. If you're heading out today, it’s a comfortable 65°F with some clouds drifting around, but don't let that fool you. By the time the sun ducks behind the Spring Mountains, you’re looking at a low of 42°F.
The Reality of the Las Vegas 10-Day Forecast
If you’re trying to plan your outfits for the next week and a half, the vibe is basically "layering or regret." We’ve got a little bit of everything coming up. Monday, January 19, looks like the peak of the week with a high of 68°F and pure sunshine. It’s basically perfect walking weather for the Strip, though the wind is going to kick up a bit from the north at about 11 mph.
After that? Things settle into a very predictable, chilly groove.
Starting Tuesday, the thermometer takes a slight dip. We’re talking highs around 61°F and 60°F for the middle of the week. By Thursday, January 22, it might even feel a bit brisk with a high of only 59°F. It’s not "snow on the Sphinx" cold, but if you’re standing in line for a club or waiting for an Uber outside Caesars Palace, you’re going to want more than a t-shirt.

Rain? In the Desert?
Actually, yeah. It’s rare, but the forecast shows a tiny 10% chance of rain popping up today and again on Wednesday. In Vegas terms, a 10% chance usually means you might see a single drop on your windshield, or it might just get a little gloomier for twenty minutes. The humidity is staying super low—around 22% to 23% for most of the week—so your skin is probably going to feel like parchment paper. Pack the heavy-duty moisturizer. Seriously.
Why the Desert Night Hits Different
One thing tourists always underestimate is the "radiational cooling." Because there’s so little moisture in the air and no "urban heat island" effect that can compete with the vastness of the Mojave, the heat just... vanishes the second the sun sets.
- Sunday Night: 42°F
- Monday Night: 43°F
- Tuesday Night: 42°F
- Wednesday Night: 42°F
It’s remarkably consistent. Whether the day was 68°F or 59°F, the night is going to drop into the low 40s. If you’re planning on hitting the Fremont Street Experience or walking between resorts, that 20-degree drop feels like hitting a wall of cold air.
The Back Half of the 10-Day Window
Looking toward next weekend, January 24 and 25, the weather 10 day las vegas nv shows a slight recovery. We’ll be back in the low 60s. Saturday should hit 63°F and Sunday will be around 62°F. It’s going to get a bit cloudier toward the end of the month, which actually helps trap a tiny bit of warmth at night—lows will "spike" to 46°F. Living the high life, right?

The UV index is also low, sitting at a 1 or 2. You probably won't burn, but the air is crisp. If you’re headed to Red Rock Canyon for a hike, this is actually the goldilocks zone. It’s way better than the 115°F madness of July, provided you have a windbreaker.
Actionable Vegas Weather Tips
Don't just stare at the numbers; use them. Here is how you actually survive a January trip to the desert based on this specific forecast:
The "Casino Sandwich" Strategy
Casinos are kept at a constant 70°F-72°F. When it’s 60°F outside, the indoors feels warm. When it’s 42°F outside at night, the indoors feels like a sauna. Wear a light jacket you can easily unzip or carry.
Hydrate Like Your Life Depends on It
With humidity hovering at 22%, you are losing water just by breathing. The "dry heat" (or dry cold) is a silent dehydrator. Drink a glass of water for every cocktail, or you'll wake up with a headache that has nothing to do with the slots.

Wind Protection
Monday is the windy day. If you have long hair, tie it back. If you’re wearing a hat, make sure it’s snug. 11 mph doesn't sound like much, but in the wind tunnels between the massive hotel towers, it can feel double that.
Check the West Side
If you’re staying off-strip towards Summerlin, remember that the elevation is higher. It’s usually about 3 to 5 degrees cooler than the Harry Reid International Airport readings you see on most apps.
The next ten days in Vegas are looking pretty stable. No major storms, no "weather alert" days on the immediate horizon, just standard, chilly desert winter. Enjoy the sun while it's up, because once 4:30 PM hits, the party continues—but the temperature definitely leaves the building.
