Las Vegas - Coldest Decades





The coldest decades on record are ranked here for Las Vegas, Nevada. The lists include decades when Las Vegas had the lowest average temperatures, the fewest hot days and the most cold days. These extremes are for temperatures observed at McCarran International Airport near downtown Las Vegas and cover seven decades, from the 1950s to the 2010s.
