What to Wear in Las Vegas
USA · 8 monthly packing guides
Las Vegas in summer is extreme heat (40-46°C / 104-115°F regularly) paired with aggressively air-conditioned casinos. The city is built around two outfit categories: dayclub/pool and nightclub. Dress codes are enforced — athletic wear and flip-flops are turned away at club doors (sneaker rules vary; XS allows clean sneakers); cover-ups are required to walk through casinos on the way to the pool. Bachelorette capital of the US; theme dressing is expected, not optional.
Choose your month below to match your layers and shoes to the weather. Across the months covered, average daily lows reach 4°C / 39°F in December; average highs reach 41°C / 106°F in July.

No. They are monthly climate averages for planning, not temperatures promised for a particular day or hour. Check the local forecast close to departure and adjust your layers and rain protection. The source, station and averaging period are listed for each month where recorded; different stations or rain-day definitions can affect comparisons.
No. Treat the capsule as a set of clothing functions: walking shoes, a base outfit, weather protection and any change for dinner or a venue's dress code. Start with equivalents you own. Adjust quantities to your trip length and laundry access; the illustrations are outfit suggestions, not a shopping requirement.
