If you stepped outside in the middle of the night expecting that typical desert chill, you probably noticed it's actually not too bad out there. Right now, the mercury is sitting at a steady 52°F. Honestly, for a January night in the Mojave, that’s practically a heatwave. The sky is perfectly clear, and the wind is just a whisper coming from the northwest at about 2 mph. Basically, it’s the kind of night where you can actually walk from the car to the casino without your teeth chattering.
But let's talk about the main event. If you’re asking what is the weather in las vegas nevada today, Thursday, January 15, 2026, you are in for a serious treat.
We are looking at a high of 70°F. Yeah, you read that right. In the dead of winter, Las Vegas is serving up literal spring vibes. It's going to be sunny all day long. Not "partly sunny" or "filtered sun"—just straight-up blue skies. The humidity is bottoming out at around 26% during the day, so it’s that classic, crisp desert air we all brag about.
Why 70 Degrees in January is a Big Deal
Most people think Vegas is just a furnace 24/7. Not true. Usually, mid-January sees highs in the high 50s. Hitting 70°F today puts us well above the seasonal average. It’s the kind of day where the pool decks at the resorts might actually see some action, even if the water is a bit "invigorating."

If you’re heading out, here’s the breakdown:
- Morning: Crisp and clear.
- Afternoon: Peaking at that glorious 70°F mark.
- Evening: Cooling back down to a low of 46°F.
- Wind: Calm northwest breezes at 2 mph.
The UV index is hovering around 3. It’s low, but don't let the "winter" label fool you. That desert sun is direct. If you’re walking the Strip or hitting a trail at Red Rock, you’ll still want a bit of sunscreen.
Packing for the Temperature Swing
The desert has this funny way of tricking you. You’ll be sweating in a t-shirt at 2:00 PM and then wondering where you left your parka by 6:00 PM. Since the low tonight is 46°F, layers are your best friend.

Light jackets? Essential.
Heavy boots? Probably overkill for today.
The sun is going to set at 4:49 PM. Once that giant orange ball drops behind the Spring Mountains, the temperature is going to plummet fast. You’ve basically got a ten-hour window of "perfect" weather before the desert reminder hits.
What This Means for Your Plans
There is a 0% chance of rain. None. Zero. You can leave the umbrella in the hotel room. This is the ideal day for outdoor dining or finally taking that helicopter tour you’ve been eyeing.

If you're a local, it’s a "windows down" kind of commute. If you're a tourist, it's the day you realize why people move here. While the rest of the country is likely shoveling snow or dealing with gray slush, Las Vegas is basking in a sunny 70°F glow.
Actionable Next Steps:
- Plan your outdoor activities between 11:00 AM and 4:00 PM to catch the peak warmth.
- Bring a medium-weight sweater or jacket if you plan on staying out past the 4:49 PM sunset.
- Hydrate more than you think; that 26% humidity will dry you out faster than the heat does.
