平均来看，最热的州应该是亚利桑那州。但创高温纪录的是在加州：“According to the World Meteorological Organization (WMO), the highest temperature ever recorded was 56.7 °C (134.1 °F) on 10 July 1913 in Furnace Creek (Greenland Ranch), California, United States, but the validity of this record is challenged as possible problems with the reading have since been discovered.”
