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-Aug.) on record in 2021, according to NOAA’s National Centers for Environmental Information.

Stacker consulted data from the NOAA’s State Climate Extremes Committee (SCEC) to illustrate the hottest and coldest temperatures ever recorded in Arizona.
