Honestly, if you're looking at the las vegas 15 day forecast right now and thinking you’ll be lounging by the pool in a bikini, I’ve got some news for you. It’s January 2026. This isn't the July "melt-your-shoes-to-the-asphalt" Vegas.
Right now, as I’m writing this on January 16, it is 50°F outside. It’s nighttime, the sky is clear, and there’s a tiny 2 mph breeze coming from the west. It’s crisp. It’s that kind of desert cold that sneaks up on you the second the sun ducks behind a casino.
What the Next Two Weeks Actually Look Like
Most people assume "desert" equals "hot" 24/7. Huge mistake.
Looking at the immediate las vegas 15 day forecast, we are seeing a weirdly consistent stretch of weather. Today and yesterday both hit a high of 70°F, which is actually quite a bit warmer than the historical January average of 57°F.
But don't let those 70-degree afternoons fool you.
The lows are still dipping into the 42°F to 47°F range every single night. If you’re walking from the Venetian to Caesars Palace at 11 PM in a t-shirt, you’re going to be miserable. Trust me. I’ve seen enough shivering tourists on the Strip to know that "dry cold" is still very much cold.
Here is the vibe for the next several days:
- Saturday (Jan 17): Sunny all day with a high of 69°F, but the clouds move in at night and the temp drops to 42°F.
- Sunday (Jan 18): Mostly cloudy and a bit cooler at 65°F. There’s a tiny 10% chance of rain, but in Vegas, that usually just means a few drops that dry before they hit the ground.
- Monday (Jan 19): Back to the sunshine for MLK Day. High of 69°F, low of 43°F. Perfect for the parade downtown.
By the time we hit the middle of next week, from January 21 to January 25, things stay pretty steady. We’re looking at highs around 64°F to 67°F. It's basically "light jacket" weather.

The Humidity Myth
You’ve heard it a million times: "It’s a dry heat." Well, in January, it’s a dry cold.
The humidity is hovering between 19% and 32% for most of this 15-day stretch. That is incredibly dry. If you aren't a local, your skin is probably going to feel like parchment paper by day three.
Bring lotion. No, seriously. Bring the heavy-duty stuff. Your lips will thank you.
What’s Actually Happening in Town?
The weather is actually working in your favor if you're here for the big events. The SHOT Show is taking over the Venetian and Caesars Forum from January 20-23, and with 61,000 people expected, you’ll be glad it’s not 110 degrees when you’re trying to catch an Uber.
The AVN Adult Expo is also happening at Virgin Hotels from the 21st to the 24th. If you’re heading to the World of Concrete expo (Jan 20-22), the 66°F forecast is basically the goldilocks zone for walking those massive convention floors.
If you’re just here for the vibes, the Backstreet Boys are at the Sphere and Blake Shelton is holding down his residency at Caesars. These are indoor things, obviously, but the walk from the parking garage to the entrance is where the las vegas 15 day forecast matters most.
The "Secret" Strategy for Vegas in January
Kinda weirdly, the best thing to do right now isn't on the Strip.
Since the daytime temps are hitting the high 60s, it is prime time for Red Rock Canyon. Usually, in the summer, you’d literally die trying to hike there. Right now? It’s perfect. Just make sure you finish your hike before 4:30 PM because once that sun goes down, the temperature falls faster than a bad gambler's bankroll.
Also, check if your hotel has a heated pool. Places like the Stadium Swim at Circa keep the water warm year-round, so you can actually watch the NFL playoffs in the water while it’s 50 degrees out. It feels like a glitch in the matrix, but it’s great.

A Few Practical Tips Based on the Current Outlook
Basically, your suitcase should look like a layer cake.
- The "Strip Jacket": You need a medium-weight jacket for the evenings. Wind speeds are low (mostly 1 to 5 mph), but even a light breeze at 42 degrees feels sharp.
- Sunglasses: The UV index is hitting 3 daily. It’s not "burn your skin off" high, but the desert sun is bright.
- Hydration: Since the humidity is so low (currently 41% tonight and dropping to 21% tomorrow), you’ll get dehydrated without even sweating. Drink more water than you think you need.
The las vegas 15 day forecast shows a lot of "mostly sunny" and "partly sunny" days ahead. We aren't seeing any major storms or "Big Cold" fronts through the end of the month. It's just solid, predictable, chilly-but-pleasant desert winter.
Next Steps for Your Trip:
Check your hotel's pool status specifically for "heated operations" before you pack the trunks. If you're planning on Red Rock or Valley of Fire, book your timed entry reservations now, as the mild 60-degree weather makes these spots sell out fast.
