See the most extreme temperatures in Utah history
On July 9, 2021, California's Death Valley reached 130 degrees Fahrenheit, according to an automated measuring system there, representing one of the highest temperatures ever recorded on the planet. The world record, also recorded at Death Valley, was 134 degrees in July 1913.
More than 210 degrees Fahrenheit separates the highest and the lowest temperatures on record in the United States, the third-largest country in the world. As some states are infamous for having blistering hot summers, others become inundated by winter storms and frigid cold. The contiguous U.S. had its warmest meteorological summer (June-August) on record in 2021, according to NOAA's National Centers for Environmental Information.
Stacker consulted 2021 data from the NOAA's State Climate Extremes Committee (SCEC) to illustrate the hottest and coldest temperatures ever recorded in each state. Each slide also reveals the all-time highest 24-hour precipitation record and all-time highest 24-hour snowfall.

Utah by the numbers
- All-time highest temperature: 117° F (St. George on July 5, 1985)
- All-time lowest temperature: -50° F (East Portal on Jan. 5, 1913)
- All-time highest 24-hour precipitation: 5.08 inches (Deer Creek Dam on Feb. 1, 1963)
- All-time highest 24-hour snowfall: 38 inches (Alta on Dec. 2, 1982)
Utah is famous for its ski resorts and ample amount of snowfall during winters, but summers can get unbearably hot. St. George's arid weather makes it far warmer than other parts of Utah, thanks to the fact that it is located in the Mojave Desert, which explains why it holds the record at 117 degrees. During the summer of 2019, Salt Lake City and other parts of the state experienced stifling heat after a high of 103 degrees was recorded in July.
