The 1980 United States heat wave was a period of intense heat and drought that wreaked havoc on much of the Midwestern United States and Southern Plains throughout the summer of 1980. It is among the most devastating natural disasters in terms of deaths and destruction in U.S. history, claiming at least 1,700 lives and because of the massive drought, agricultural damage reached US$20.0 billion (equivalent to $63 billion in 2020 dollars). It is among the billion-dollar weather disasters listed by the National Oceanic and Atmospheric Administration.
