You're standing on Las Vegas Boulevard, the neon humming above you, and suddenly you realize that "desert" doesn't always mean "hot."
Honestly, the 10 day weather Las Vegas Strip forecast is looking like a masterclass in why you should never trust a postcard. Most people pack for Sin City thinking they’ll be lounging poolside with a frozen margarita in 100-degree heat. If you do that this week, you’re going to be shivering in line at the buffet.
Right now, as of Sunday, January 18, 2026, the Strip is sitting at a crisp 43°F.
It’s nighttime, the sky is partly cloudy, and there’s a light 4 mph breeze coming from the west. If you’re heading out to see the Bellagio Fountains, you better have a coat. The desert loses its heat the second the sun dips behind the Spring Mountains, and this week is no exception.
The 10-Day Breakdown: Sun, Clouds, and a Bit of a Chill
Don't let the "sunny" icons on your phone app fool you into thinking it's t-shirt weather. We are looking at a stretch where the highs feel decent, but the lows are basically refrigerator temperatures.
Sunday, January 18 (Today) Expect a high of 64°F with partly sunny skies. It’s actually one of the nicer days for a walk. Tonight, it clears up completely, dropping back down to 43°F.

Monday, January 19 (Tomorrow) This is the peak of the week. We’re hitting 67°F under full sun. But watch out for the wind—it’s kicking up to 10 mph from the north. That’s enough to make a 60-degree day feel like 50 if you’re caught in a shadow between the massive resorts like Caesar’s or the Venetian.
Tuesday, January 20 The mercury takes a dip. We're looking at a high of 60°F and a low of 42°F. It’s sunny, but that air is going to feel sharp.
Wednesday & Thursday (Jan 21-22) Mid-week gets a little gloomy. Wednesday stays at 60°F but turns cloudy. Thursday drops even further to a high of 58°F. Interestingly, the low on Thursday actually creeps up to 46°F because the cloud cover acts like a giant space blanket, trapping what little heat the concrete absorbed during the day.
The Late Week Rebound (Jan 23-27) By Friday, the sun is back in full force. Highs will hover between 62°F and 65°F through next Tuesday. The lows stay remarkably consistent, ranging from 44°F to 47°F.
Basically, the next ten days are the definition of "layering weather."

Why the Strip Has Its Own Microclimate
Most people check "Las Vegas weather" and think they’re covered. They aren't.
The Strip isn't actually in the city of Las Vegas; it's mostly in Paradise and Winchester. Because of the massive amount of concrete, glass, and asphalt, the "Urban Heat Island" effect is real here. However, in January, the towering hotels create massive wind tunnels.
Have you ever walked past the Wynn or the Encore when the wind is blowing? It’s brutal. Even a 3 mph or 4 mph wind (which is what we’re seeing for most of this forecast) can feel significantly colder when it's funneled between 50-story buildings.
Humidity is staying incredibly low—around 22% to 25% for most of the week.
While that sounds great for your hair, it’s a nightmare for your skin and hydration. You’ll feel fine, then suddenly realize you’ve got a headache because the desert air is literally sucking the moisture out of you. Drink twice as much water as you think you need, especially if you’re hitting the casino floor where the air is filtered and even drier.

What to Actually Pack (The Expert List)
Forget the swimsuits unless your hotel has a heated indoor pool or a very brave outdoor heater setup. Most locals won't even look at a pool until April.
- The Mid-Weight Jacket: A leather bomber, a denim jacket with a lining, or a stylish wool overcoat. You need something that looks good for dinner but actually stops the wind.
- Light Sweaters: Cashmere or light knits are your best friends. You’ll be constantly moving from 60-degree outdoors to 72-degree indoors.
- Real Shoes: Leave the flip-flops in the suitcase. Stick to Chelsea boots, stylish sneakers, or loafers. The Strip involves miles of walking, and cold toes make for a miserable night at the craps table.
- A Scarf: Sounds dramatic for Vegas, right? It isn't. When that sun goes down at 4:30 PM and the temperature drops 20 degrees in an hour, you'll be glad you have it.
Rain Chances: Will You Get Wet?
Short answer: Probably not.
The chance of precipitation over the next 10 days is hovering around 0% to 10%. Sunday has a tiny 10% chance of a stray shower, and Saturday/Sunday (Jan 24-25) might see a 10% blip, but "rain" in Vegas usually means three drops on your windshield and a rainbow over the Strat.
January averages only about 0.5 to 0.6 inches of rain for the entire month. You are much more likely to be bothered by the dry air than a downpour.
Actionable Tips for Your Trip
- Lip Balm is Non-Negotiable: With humidity hitting 22%, your lips will crack before you finish your first slot pull. Buy a stick at the airport.
- Check the UV Index: Even though it’s "cool," the UV index is still hitting 2. It’s not high, but if you’re out hiking Red Rock Canyon during those sunny Monday hours, the desert sun can still catch you off guard.
- Sunset Planning: The sun sets early in January. Plan your outdoor photos (like the Welcome to Las Vegas sign) for between 1:00 PM and 3:00 PM when the light is best and the temperature is at its daily peak.
- The "Vegas 10-Degree Rule": Whatever the forecast says, subtract 10 degrees if you’re standing in the shade of a skyscraper.
The next 10 days on the Las Vegas Strip are going to be beautiful, crisp, and perfect for sightseeing without the soul-crushing heat of July. Just make sure you bring a jacket that looks as good as the rest of your outfit.
Next Steps for Your Trip
To make the most of this 60-degree weather, you should:
- Book outdoor tours like the High Roller or a walk through the Neon Museum for the afternoons of Monday or Tuesday when the sun is brightest.
- Verify your hotel's pool status if you were planning on a dip; many Strip pools close for maintenance in January regardless of the temperature.
- Pack a portable power bank; cold weather (and constant photo-taking) drains phone batteries faster than usual.
