So, you're looking at the 14 day forecast las vegas and thinking, "Hey, it's the desert, I'll just pack my flip-flops and a tank top, right?"
Honestly, that’s the fastest way to end up shivering in a $40 souvenir hoodie you bought out of desperation at a Strip gift shop.
Vegas in January is a bit of a trickster. Right now, it's actually pretty gorgeous—69°F and sunny today, Saturday, January 17. But don't let that afternoon sun fool you into thinking it's pool weather. The second that sun dips behind the Spring Mountains, the temperature falls off a cliff. We're talking a drop down to 43°F tonight.
That’s a 26-degree swing. Your body is going to feel every single one of those degrees.

The Reality of the 14 Day Forecast Las Vegas
Most people see "sunny" and "60s" on their weather app and assume it’s basically spring. It’s not. It’s high-desert winter. If you're walking from the Venetian to Caesars Palace at 10 PM, the wind tunneling between those massive towers can make 43 degrees feel like a freezer.
What the Next Week Actually Looks Like
The upcoming week is sticking to a very specific script. We’ve got a mix of bright sun and some "meh" cloudy days.
- Sunday, Jan 18: It’s gonna be mostly cloudy with a high of 65°F. There’s a tiny 10% chance of rain during the day, so maybe keep an eye on the sky if you're doing an outdoor tour.
- Monday, Jan 19: Back to full sun and 69°F. This is basically the "Goldilocks" day of the week—perfect for walking the Strip without breaking a sweat.
- Tuesday & Wednesday: Things cool off just a touch. Tuesday hits 65°F and Wednesday stays around 66°F with some clouds moving back in.
Basically, the daytime is for light jackets, and the nighttime is for actual coats. I’ve seen tourists trying to do the "Vegas nightlife" look in tiny dresses and no stockings in January, and they look miserable. Don't be that person.

The Wind and Humidity Factor
The wind right now is pretty chill—mostly around 5 mph coming from the North or Northeast. It’s not the "blow your hat off" kind of wind Vegas gets in the spring, but it adds a bite to the air.
Also, the humidity is sitting at a bone-dry 12% to 19%. If you aren’t used to desert air, your skin is going to feel like parchment paper by day three. Your nose might even get a little crusty. It’s gross, but it’s the reality of the Mojave.
Why the "Coldest Month" is Actually Great
Even though January is technically the coldest month in Vegas, it’s arguably one of the best times to visit if you actually want to do things.

In July, you can’t walk more than a block without feeling like you’re being slow-roasted. Right now? You can hike Red Rock Canyon or the Valley of Fire and it feels amazing. The "send temps" (as climbers call them) are perfect.
Expert Gear Check
If you’re packing based on the 14 day forecast las vegas, here is the "real talk" list of what you need:
- Layers, obviously. A t-shirt, a hoodie, and a medium-weight jacket. You’ll be shedding and adding these all day.
- Lip balm and heavy moisturizer. Not the cheap stuff. Get the medical-grade stuff.
- Real shoes. You will walk 10+ miles a day. I promise. Even if you think you’re taking Ubers, you’ll end up walking through the labyrinth of the casinos.
- A refillable water bottle. You dehydrate faster here because the sweat evaporates before you even feel it.
What's Happening Around Town
Since the weather is so mild, the city is leaning into the "Winter Swim" vibe. Places like Stadium Swim at Circa keep their pools at 94°F year-round. It’s a weird sensation to have your body in hot water while your ears are cold, but it’s a total Vegas experience.
If the 14 day forecast las vegas starts showing those 70°F peaks toward the end of the month (like the 70°F predicted for Tuesday, Jan 27), that’s your cue to book your outdoor tours. Hoover Dam, Grand Canyon, or even just a long walk Downtown to see the Fremont Street murals.
Actionable Takeaways for Your Trip
- Check the lows, not just the highs. If the low is under 45°F, you need a real jacket for the evening.
- Hydrate like it's your job. Aim for double your usual water intake to combat the 12% humidity.
- Book outdoor activities for mid-day. The window between 11 AM and 3 PM is your prime "warm" time.
- Don't trust the sun. It’s bright, but it doesn't always mean it's warm. The UV index is currently low (3), so you won't feel the heat on your skin like you do in the summer.
Stay warm, keep your skin hydrated, and enjoy the fact that you aren't melting in 115-degree heat. Vegas in the winter is a different beast, but once you figure out the layering game, it’s actually the most comfortable time to be here.
