So, you're looking at the Las Vegas weather forecast 14 day and trying to figure out if you actually need that heavy coat or if you can skate by with a light hoodie. Honestly, the desert is a bit of a liar this time of year. People see "Nevada" and "Desert" and immediately pack for Coachella.
Big mistake.
Right now, as of Sunday, January 18, 2026, Vegas is sitting in a bit of a "mostly cloudy" mood. It’s 62°F out there. Not exactly poolside weather, but definitely better than the sub-zero wind chills currently hitting the Midwest. If you’re arriving today, expect a high of 65°F. But here is the thing: the moment that sun dips behind the Spring Mountains, the temperature is going to plummet to 42°F.
The Mid-January Shift
Tomorrow, Monday, January 19, things look a bit more "classic Vegas." We’re talking full sun and a high of 69°F. It’s that perfect, crisp desert air where you feel like a million bucks in the sun but reach for a sweater the second you hit the shade.
But don't get too comfortable.
By Tuesday and Wednesday, we’re sliding back into the low 60s. Highs will be around 64°F and 63°F respectively. It’s a subtle shift, but in the desert, a five-degree drop combined with the lack of humidity makes it feel significantly cooler.
Why the 14-Day Outlook Matters
Looking further out, the Las Vegas weather forecast 14 day shows a pretty stable pattern for the end of January 2026. We aren't seeing any massive "Nokaen-style" storm disruptions—referring to that early typhoon that popped up near the Philippines recently—but we are seeing typical high-pressure stability.
Saturday, January 24, looks like the sweet spot for outdoor plans with a high of 67°F. If you’re planning on hitting the Red Rock Canyon for a hike, that’s your window.
Interestingly, as we push toward the final days of the month, like Tuesday, January 27, and Wednesday, the 28th, temperatures are actually projected to climb back up to 70°F. It’s a bit of a pre-spring tease.
Humidity and the "Dry Cold" Myth
You've probably heard someone say, "It’s a dry heat." Well, in January, it’s a dry cold. Humidity right now is hovering around 20% to 27%.
What does that actually mean for you?
Basically, your skin is going to turn into parchment paper and you’ll be chugging water like you’re in a marathon even though it’s only 60 degrees. The lack of moisture in the air means there’s nothing to hold onto the heat. That's why the daily range is so wild—often a 25-degree difference between lunch and dinner.
What to Actually Pack
Forget the swimsuits unless you're staying at a place like Stadium Swim at Circa, which stays heated year-round. For everywhere else, you need layers.
- The Base: T-shirt or light long-sleeve.
- The Mid: A denim jacket or a light puffer.
- The Emergency: A beanie. Seriously. When the wind picks up off the desert floor at night, you'll want it.
Wind speeds over the next week are staying pretty mellow—mostly between 1 mph and 5 mph. On Monday, January 19, we might see a 5 mph breeze from the north, which will make that 69°F feel a bit more like 64°F.
Beyond the Strip
If you’re planning to head out to Mt. Charleston, keep in mind that the Las Vegas weather forecast 14 day for the city doesn't apply up there. While it's 65°F at the Bellagio, it could easily be 35°F and snowing at the resort. It’s only a 45-minute drive, but it’s a different world.

The 14-day outlook suggests mostly clear to partly cloudy skies through the end of the month. Rain chances are incredibly low—mostly 0% to 10%. We had a soggy start to 2026 with some New Year's rain, but the tap seems to have turned off for now.
Actionable Travel Tips for the Next 14 Days
- Check the UV Index: Even when it’s 63°F on Wednesday, the UV index is around 2 or 3. It’s low, but if you’re out hiking all day, the desert sun will still get you.
- Hydrate more than you think: The 22% humidity will dehydrate you faster than the summer heat because you won't feel yourself sweating.
- Book outdoor dinners for the weekend: Friday, Jan 23, and Saturday, Jan 24, have the most stable evening temps (lows in the mid-40s) compared to the start of the week.
- Watch the North Wind: Any time the forecast mentions a "North" wind (like on Monday), expect it to feel about 5 degrees colder than the thermometer says.
Stay flexible, keep a jacket in the car, and enjoy the fact that you aren't shoveling snow. Vegas in late January is a vibe, as long as you aren't expecting a heatwave.
