Because most visitors experience Las Vegas behind the air-conditioned comfort of the indoors, Las Vegas has become a year-round destination no matter how extreme the weather. However, traffic into the city slows with the cooler temperatures of December and January, and at the height of the heat in August.
While Las Vegas enjoys sunshine for over 300 days each year, the coldest and hottest months of the year tend to keep visitors away. According to the Las Vegas Convention and Visitors Authority, traffic traditionally slowed from mid-July through the end of August, but the lure of wave pools and lazy rivers such as those at Mandalay Bay, the MGM Grand and Monte Carlo has attracted visitors back to the city.
Casinos and hotels offer discounted room rates Sundays through Thursdays. Rates are also lower from November through January, although the exceptions are the Thanksgiving holiday and the few days before and after the New Year. Coincidentally, the buffet lines are also the least crowded during this period.
Airfare for flights into Las Vegas hits rock bottom when the searing heat reaches its height in August.
While the Las Vegas off-season generally means thinner crowds and steeper discounts on lodging, airfare, attractions and food, rates can suddenly climb if a convention or special event arrives in town.
