What to Wear in Las Vegas in December (Cold Nights, Long Walks and Dress Codes)

The short answer

Las Vegas in December averages a high of about 57°F and a low near 40°F, and it's dry. Pack layers for sunny days, a real coat for night walks between resorts, comfortable shoes for long distances, and one dressy outfit. Evenings can feel much colder than the daytime sun suggests.

“The desert fools people twice in December. The sun says you can skip the coat, then the sun sets, and you're in a little dress on a windy overpass. Bring the coat. Vegas is the one town where you won't be overdressed in it.”Her take

How cold is Las Vegas in December?

Colder than most visitors expect. National Weather Service normals put the average high near 57 degrees Fahrenheit and the average low around 40, and there's only about half an inch of precipitation in the entire month. Expect bright, dry days and sharp, chilly nights, with occasional wind that makes the Strip's walkways and overpasses feel colder.

Dry air matters too. Your skin and lips will feel it quickly, and the air inside hotels is usually dry as well. Pack lip balm and a richer moisturizer. Check the 10-day forecast before you pack, since a mild or cold spell can shift things by several degrees either way.

What to pack for four days

Keep colors simple so everything can mix. Black, camel and one jewel tone will do, and a carry-on is enough if you wear your coat and bulkiest shoes on the plane.

One warm coat: a wool or lightweight down style that fits over a dress.
One light layer: a leather jacket or blazer for sunny afternoons.
Two pairs of pants or jeans, one dark and dressy enough for dinner.
Three tops: a fine knit, a turtleneck and something silky for evenings.
Two evening outfits: one dress or jumpsuit and one set of dressy separates.
Three pairs of shoes: cushioned sneakers or flat boots, heeled ankle boots, and dressy shoes.
Sheer or opaque tights, a large scarf and a small crossbody bag.

What to wear during the day

Daytime is relaxed: jeans, a good knit and a jacket fit nearly anything from brunch to shopping. Bring a layer you can take off, because casinos and malls can be warm and it's often chillier in the shade than you'd expect. Sunglasses are worth carrying, even in December, since the desert sun is bright and sits low in the sky.

The biggest surprise for first-timers is the walking. Resorts look close together but are often a long walk apart, and you'll cross large casino floors and pedestrian bridges to get anywhere. Wear cushioned, broken-in shoes in the daytime, and save your dressiest pair for evenings you'll spend mostly sitting.

What to wear to shows and dinner

Most Las Vegas shows don't have a strict dress code, so you'll see everything from jeans to cocktail dresses in the same row. Smart casual is a safe minimum. Think dark jeans or tailored pants with a silky top and heeled boots. Theaters can be cool, so a jacket or wrap across your shoulders is useful.

Fine-dining restaurants vary more. Some have a stated dress code that excludes shorts and athletic wear. Look on the restaurant's website before you go, and aim for a dress, a jumpsuit or tailored separates. A velvet blazer or a metallic shoe makes it feel like a night out without needing a new outfit.

What to wear to a nightclub in December

Clubs are the dressiest part of Las Vegas, and dress codes are real, even if they vary. Expect them to want cocktail dresses or dressy separates, with heels or dressy hard-soled flats, and to turn away athletic wear, sneakers, flip-flops and very casual looks at the door. Check the club's website the day you're going.

Most clubs have a coat check, usually for a fee, and some expect heavier coats to be checked, so wear your warm coat and hand it in. A short mini or sequined dress with sheer black tights is warmer than bare legs, and it looks deliberate. Keep flat, foldable shoes in your bag or your hotel room for the trip back, especially if the walk ends up longer than you planned.

What about New Year's Eve in Las Vegas?

The Strip's New Year's Eve crowd stays outdoors in the cold for hours, often after sunset, so dress more like you're going to an outdoor event than to a club. A warm coat, thermal tights under a dress or dressy pants, flat boots and a hat are the sensible choice. Your party heels will only hurt.

If you're heading to an event indoors afterward, check for coat check before you go, and check the venue's bag policy, since rules vary. A small crossbody or clutch is the safest choice. Keep your ID and phone on you, in a crossbody or an inside pocket.

Questions people ask

Is December too cold for a dress in Las Vegas?

No, if you add tights and a warm coat for the walk. Indoors you'll be comfortable, so just plan for the time spent outside after dark.

Do I need a heavy coat in Las Vegas in December?

You'll want at least a warm wool or light down coat for nights, when temperatures often drop near 40 degrees. A heavy parka usually isn't necessary.

Can I wear jeans to a show in Las Vegas?

Yes, in most theaters. Clean, dark jeans with a nice top are common. Check for any specific show or restaurant rules, particularly for fine dining.

Can I swim in Las Vegas in December?

Some resort pools stay open on a limited schedule and may be heated, but check with your hotel. Outside air is usually too cool for most people to enjoy lounging by a pool.

The takeaway

Sunny days, cold nights, long walks. Pack layers, a real coat and two kinds of shoes, then check the dress code on anything you're booking.
