Honestly, if you're picturing yourself lounging by a resort pool in a swimsuit this week, you might want to rethink that packing list. People always assume the desert is a furnace year-round, but January in the Valley is a whole different beast. Right now, as we hit mid-January 2026, the las vegas nv weather 10-day forecast is showing us a city that’s surprisingly comfortable by day but properly frigid once the neon lights flicker on.
We are currently seeing a "Goldilocks" stretch. It’s not too hot, not too cold—at least while the sun is up. But there is a specific rhythm to Vegas weather this time of year that catches tourists off guard every single time.
Breaking Down the Las Vegas NV Weather 10-Day Forecast
The numbers don't lie, but they can be deceptive if you don't know how the desert air works. Today, January 15, we're looking at a high of 70°F with basically zero wind. That sounds like perfection, right? It is, until you realize the low is dropping to 46°F tonight. That’s a 24-degree swing.
As we look through the next week and a half, the consistency is actually pretty wild. We are stuck under a ridge of high pressure that is keeping things stable, dry, and clear.

The Daily Outlook: Jan 15 to Jan 24
- Thursday (Today): A peak of 70°F. It’s arguably the best day of the week. Very light south winds at 2 mph.
- Friday, Jan 16: Another 70°F day. Pure sunshine. The northwest wind picks up just a tiny bit to 5 mph, which might add a slight "bite" to the shade.
- The Weekend (Jan 17-18): Saturday holds steady at 68°F, but Sunday dips slightly to 65°F. We’ll see some "partly sunny" intervals on Sunday, with a negligible 10% chance of a stray shower. Don't bet on the rain; Vegas rarely pays out on that.
- Next Week (Jan 19-22): Expect a very repetitive cycle. Highs will hover between 66°F and 68°F. Monday (MLK Day) looks beautiful at 68°F and sunny.
- The Wind Factor (Jan 24): Keep an eye on Saturday, January 24. While the high stays at 65°F, the wind is forecasted to jump to 16 mph from the northwest. In the desert, 16 mph feels significantly colder than it looks on paper.
Why "Above Normal" Still Feels Cold
The National Weather Service in Las Vegas has been noting that we are technically in an "above-normal" temperature trend. Usually, January averages a high of about 57°F. So, hitting 70°F today is actually a massive bonus.
But here’s the thing most people get wrong: humidity. Or rather, the lack of it. With humidity sitting around 21% to 27% this week, your body loses heat much faster than it would in a humid place like Florida or Houston. When that sun goes behind a building on the Strip, the temperature feels like it drops 10 degrees instantly.
I’ve seen it a thousand times—people walking around in shorts at 2:00 PM, and by 6:00 PM, they’re huddled in a CVS buying an overpriced souvenir hoodie because they're shivering.

The Microclimates of the Valley
If you’re planning on leaving the Strip, the las vegas nv weather 10-day forecast changes depending on your elevation.
If you head out to Red Rock Canyon for a hike, subtract about 5 to 7 degrees from the official McCarran (Harry Reid) airport reading. If you’re heading up to Mt. Charleston, you’re looking at actual winter conditions. While the city stays dry with 0% precipitation chances for most of this forecast, the mountains often trap whatever moisture is lingering in the air.
What to Pack for This 10-Day Window
You’ve gotta layer. It’s the only way to survive a Vegas January without misery.

Basically, you need a "three-stage" outfit. A light t-shirt for the midday sun, a medium sweater or denim jacket for the late afternoon, and a proper coat if you plan on walking between casinos at midnight. The overnight lows are hovering around 42°F to 44°F for the duration of this forecast. That is cold.
Actionable Advice for Your Trip
- Hydrate like it’s 110 degrees. Even though it's 70°F, the dew point is incredibly low (around 27°F). You won't feel sweaty, but the air is literally pulling moisture out of your skin and lungs.
- Sunscreen is non-negotiable. The UV index is hitting a 3 this week. It’s not "burn in ten minutes" levels, but with clear skies and 8 hours of sunshine, you'll get a "Vegas glow" (read: lobster face) faster than you think.
- Check the wind on Jan 24. If you’re planning outdoor dining or a helicopter tour toward the end of next week, that 16 mph wind forecast might cause some turbulence or chilly patio experiences.
- Take advantage of the "Chilly" mornings. If you’re a runner, the 7:00 AM window is perfect. It’ll be around 48°F—crisp, clear, and the Strip is empty.
The current las vegas nv weather 10-day forecast is essentially giving us a perfect window for sightseeing without the brutal heat exhaustion of July. Just respect the desert nights, or they'll remind you exactly where you are.
Next Steps:
Monitor the wind speeds for the weekend of the 24th, as gusts in the Colorado River Valley tend to be higher than the valley floor. If you're heading toward Hoover Dam, expect conditions to feel about 5-10 mph windier than the Strip forecast suggests.
