This United States map indicates every state and territory, with each recording its own hottest dates and temperatures.
California’s Death Valley logged the hottest temperature in America. On July 10, 1953, the area recorded a scorching 134 degrees Fahrenheit (57 degrees Celsius), which is about half more than a person’s normal body temperature.

Ten areas, including five U.S. states, have their highest record temp at less than or equal to 105 deg. F (41 deg. C), the warmest range in this chart. Puunene, Hawaii has the lowest temperature among all those recorded, at just 98 F (37.2 C), comparable to a borderline normal human body temperature.
