United States temperature extremes

For the United States, the extremes are 134 °F (56.7 °C) in Death Valley, California and −79.8 °F (−62.1 °C) recorded in Prospect Creek, Alaska.

Among the U.S. states, Hawaii has both the lowest state maximum of 100 °F (37.8 °C) and the highest state minimum of 12.0 °F (−11.1 °C). Indeed, tropical locations such as Hawaii often have the lowest recorded temperature ranges, sometimes with a difference of as little as 62 °F (34.4 °C).^{[citation needed]} The most dramatic temperature changes, however, occur in North American climates susceptible to Chinook winds. For example, the largest 2-minute temperature change of 49 °F (27.2 °C) occurred in Spearfish, South Dakota, a rise from -4 to 45 °F (-20 to 7.2 °C). The largest recorded temperature change over a 24-hour period occurred on January 15, 1972 in Loma, Montana, when the temperature rose from -54 to 49 °F (-47.8 to 9.4 °C).
