Clothing

Insulated jacket or wool coat
Las Vegas January lows drop to 38°F on the Strip — many visitors pack only for pool weather and are caught in the cold during evening walks between casinos.
Layering sweaters
The 20°F gap between 58°F January afternoons and casino interiors held at 68°F creates constant indoor-outdoor temperature shock that requires easy-remove layers.
Long-sleeve thermal undershirt
Las Vegas January air is bone-dry with humidity under 30% — the arid desert cold at 38°F feels sharper than humid coastal cities at the same temperature.
Jeans or tailored trousers
Las Vegas entertainment venues — from the Sphere to Wynn nightclubs — enforce smart-casual dress codes year-round, and January is a peak indoor-venue month.
Dressier top or cocktail-ready blouse
CES week in early January brings a professional crowd to the Strip; evenings at ARIA and the Venetian skew dressier during the convention season.

Footwear

Cushioned walking shoes or sneakers
The Las Vegas Strip covers 4+ miles of concrete — January visitors still average 6–8 miles of daily walking across casino floors, parking garages, and outdoor promenades.
Heeled ankle boots
Ankle boots handle Las Vegas January evenings at 38°F and add polish for casino dining at Gordon Ramsay or Joël Robuchon without sacrificing warmth.
Warm socks (2–3 pairs)
Casino marble floors at the Bellagio and MGM Grand are cold underfoot — warm socks prevent feet from aching during long gambling or show-watching sessions.

Accessories

Scarf
January nights near the Bellagio fountains and the outdoor sections of Fremont Street Experience drop to 38°F — a scarf is the fastest way to recover warmth between venues.
Sunglasses with UV400 lenses
Las Vegas January UV is stronger than most realize — the desert valley at 2,001 ft elevation eliminates atmospheric haze and post-rain skies are especially bright and glare-heavy.
SPF 50+ lip balm and hand cream
Las Vegas January humidity averages below 30% — lips and knuckles crack quickly in dry desert air even when daytime highs are only 58°F.
Small crossbody bag
New Year's holiday traffic persists through January on the Strip — a crossbody bag keeps hands free and essentials secure in busy casino crowds at the Cosmopolitan and ARIA.

Gear

Packable rain jacket
Las Vegas averages 4 rainy days in January — Pacific winter storms occasionally deliver several hours of steady rain to the uncovered Strip, and most visitors never think to pack for it.
Compact travel umbrella
A compact umbrella complements a rain jacket for January Strip walks where you may be moving quickly between casinos and need hands-free coverage — the Bellagio-to-Caesars stretch is fully exposed.
Waterproof tote or dry bag
Las Vegas January rain is infrequent but soaks leather bags and unprotected electronics quickly — a small waterproof tote protects your phone and wallet during the 4 possible rainy days on the Strip.

Local tips for Las Vegas in January

CES (Consumer Electronics Show) runs in early January and brings 100,000+ attendees to the Strip — book dining reservations and show tickets at least a week in advance and expect higher Uber surcharges throughout the convention.

The outdoor Bellagio fountain show runs on a winter schedule in January — arrive at 38°F post-sunset fully dressed for the cold, as the crowd is dense and you may wait 10–15 minutes for the next show.

Las Vegas casino interiors are kept at 68°F year-round — even on a 38°F January night, you'll need to shed your coat the moment you step inside; carry a bag large enough to hold bulky outerwear so it doesn't slow you down.
