U.S. state and territory temperature extremes explained

The following table lists the highest and lowest temperatures recorded in the 50 U.S. states, the District of Columbia, and the 5 inhabited U.S. territories during the past two centuries, in both Fahrenheit and Celsius.^[1] If two dates have the same temperature record (e.g. record low of 40°F in 1911 in Aibonito and 1966 in San Sebastian in Puerto Rico), only the most recent date is shown.
