Las Vegas Weather

The most comfortable times to be in Las Vegas are the spring and fall. In April and May, daytime temperatures are delightful, between 70 and 90°F. In September and October, the summer heat has abated, and the pools remain open.

Winter is a distinctly different season, with snowcapped mountains in the distance, windy and chilly days, and surprisingly cold nights. The three weeks before Christmas find Las Vegas nearly deserted, with rooms going for bargain rates and hardly a traffic jam on the Strip.

Summer is a time of dry, uncomfortably hot weather (sometimes literally 110°F in the shade), when lounging at an outdoor pool requires protection from the relentless desert sun. You'll probably find yourself continuously thirsty. At the height of the heat, however, hotels offer their lowest rates.
