What's The Weather In Vegas In December

So you’re thinking about Vegas in December. Good news: you won’t melt, and you probably won’t need a parka the size of a minivan. The weather is basically desert cozy with a side of sunshine.

December sits right in the middle of Las Vegas winter. That means crisp mornings, mild afternoons, and nights that remind you the desert isn’t always a giant hairdryer. Locals call it sweater weather; tourists call it “wait, why is my margarita shivering?”

What December Actually Feels Like

Average daytime highs land around 58°F (14°C). If the sun is out — and it usually is — you might feel warm enough to ditch the jacket on a sunny patio. But the moment that sun dips, the temperature drops like a bad poker hand.

Average overnight lows hover near 39°F (4°C), with some nights dipping into the 30s and occasionally the 20s. So yes, Vegas gets cold. It’s not Midwest cold, but it’s not pool-party weather either.

Humidity is low, which keeps the air dry and the skies clear. Your skin might feel like parchment by day three, so pack lotion. Your hair, on the other hand, may finally behave.

Daytime: Light Jacket Weather

From roughly 11 a.m. to 4 p.m., Vegas feels pretty pleasant. A light jacket, hoodie, or denim jacket usually does the trick. If you’re walking the Strip, you’ll heat up fast anyway.

That’s because casino hopping involves a lot of walking. You’ll go from cool outdoor air to warm, smoky, over-air-conditioned interiors. Layers are your best friend here.

A T-shirt under a sweater under a jacket sounds excessive until you experience the indoor-outdoor temperature whiplash. Then you’ll feel like a genius. A slightly sweaty genius, but still.

Nighttime: Bring the Fuzzy

Once the sun clocks out, December nights in Vegas get chilly. A cute going-out outfit might look amazing in the hotel lobby. Outside, it might make you question every life choice that led to that miniskirt.

Pack a proper coat if you plan to walk the Strip after dark. Heated patios and fire pits help, but they won’t save your exposed ankles. And yes, people still wear heels in December — they’re just braver than the rest of us.

Las Vegas in December [Weather, Events, What to Wear, Tips]

The wind can make it feel even colder. A breezy night on the pedestrian bridges feels like nature’s way of saying, “Should’ve brought a scarf, huh?”

Rain, Snow, and Other Plot Twists

December is one of the drier months in Las Vegas. Rain isn’t impossible, but it’s not exactly a daily event. You might see a quick shower, and locals will drive like it’s the apocalypse.

Snow happens, but rarely on the Strip. The surrounding mountains and higher elevations can get a dusting, which looks gorgeous from a heated hotel room. If the valley gets flurries, everyone posts about it like they’ve witnessed a unicorn.

So don’t cancel your trip over snow fears. Just keep an eye on the forecast if you’re driving to Red Rock or Mount Charleston. Those areas play by different winter rules.

What to Pack for Vegas in December

Think layers, layers, layers. Start with a base layer that works indoors, add a sweater or fleece, and top it with a jacket or coat. You’ll be ready for sunshine, shade, casinos, and that random cold gust.

Comfortable shoes are non-negotiable. The Strip is deceptively long, and December’s cool air won’t stop your feet from filing a complaint. Bring lip balm, moisturizer, and sunglasses too, because the winter sun is sneaky.

If you’re planning a fancy dinner or a show, you can still dress up. Just add a stylish coat and maybe some tights. You’ll look great and avoid turning into a human icicle.

Pools, Patios, and Outdoor Fun

Most resort pools close or shift to heated-only status in December. A few heated pools and hot tubs stay open, especially at nicer properties. But this isn’t the month for cannonballs and frozen daiquiris by the pool.

Outdoor adventures are still fantastic, though. The cooler weather makes hiking at Red Rock Canyon way more enjoyable than in July. Just bring a jacket and check for icy trails.

Patios with heaters are a whole vibe. Sip a cocktail, wrap yourself in a provided blanket, and pretend you’re not secretly dreaming of a hot bath. It’s charming, honestly.

New Year’s Eve and Holiday Sparkle

December in Vegas goes big on holiday cheer. The Bellagio Conservatory, Ethel M Chocolate Factory lights, and ice rinks around town make it feel festive. The Strip gets crowded, sparkly, and full of people in Santa hats.

New Year’s Eve is its own beast. Expect big crowds, road closures, fireworks, and cold temperatures, so dress warmly while you wait for midnight. A sequined jacket over a thermal shirt is a valid strategy.

If you’re not into the NYE chaos, visit earlier in December. You’ll get the decorations, the shows, and the cozy weather without the shoulder-to-shoulder madness.

The Bottom Line? December in Vegas Is a Delight

Vegas in December isn’t a tropical getaway, and that’s okay. It’s a crisp, sunny, sparkly escape where you can wear a sweater, drink hot cocoa, and still enjoy the neon glow. The weather keeps you cool, but the city keeps you warm.

So pack your layers, book that show, and don’t forget your coat for the nighttime stroll. You’re going to have a blast. And if you get a little chilly, that’s just Vegas giving you an excuse to cozy up.
