December-February
Cooler weather and an abundance of holiday parties make winter an extremely popular time to visit Sin City. You'll want to make flight and hotel reservations at least a month in advance, especially if you're hoping to ring in the new year Vegas-style.
Although you probably could wear shorts during the day in Vegas, a comfortable pair of jeans is your best bet for Vegas in the winter. Men should also bring a mix of short and long sleeved collared shirts, as well as a T-shirt or two and a hoodie.
The cool season lasts for 3.2 months, from November 19 to February 24, with an average daily high temperature below 66°F. The coldest month of the year in Las Vegas is December, with an average low of 39°F and high of 58°F.
