United States temperature extremes

United States temperature extremes

For the United States, the extremes are 134.8 °F (57.1 °C) in Death Valley, California and −82.8 °F (−63.8 °C) recorded in Prospect Creek, Alaska.

Among the U.S. states, Hawaii has both the lowest state maximum of 100 °F (37.7 °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 degrees Fahrenheit (34.4 degrees Celsius). 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 °F (−20 °C) to 45 °F (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 °F (−47 °C) to 49 °F (9 °C).

Some North Americans and Europeans keep a record of the temperature extremes they have experienced as an indicator of the extent of their travel. There is much variation in temperature due solely to climate, and excluding travel, the average American might expect to experience a lifetime temperature range of between 90 to 135 F° (50 and 75 C°).Fact|date=February 2007 Europeans, unless they travel to places with unusual climates, tend to experience smaller temperature ranges due to the more moderate temperatures observed on the continent (excluding the freak summer of 2003).
