Las Vegas - Extreme Daily Precipitation for Each Year





This page lists the biggest rainstorms or snowstorms of the year in Las Vegas, Nevada along with the date they occurred. The information answers questions like: When was the last time more than 1.5 inches of precipitation landed on Las Vegas in a single day? What was the rainiest day of 2018?

The list gives the highest daily precipitation for each year in Las Vegas and the date that it happened. A date with a plus sign beside it means the same amount of moisture also fell on at least one other day earlier that year.

These records go back to 1931, with a few years missing data. During that time the heaviest downpour measured for a single day was 2.58 inches (65.5 millimetres) on August 21, 1957.

Since 1949 the precipitation extremes were observed at McCarran International Airport. Before then, the weather station was at downtown Las Vegas.
