Drought developed in the Western, Midwestern and Northeastern United States in the summer of 2020.[1] Similar conditions started in other states in August 2020, including Iowa, Nebraska and certain parts of Wisconsin and Minnesota. At the same time, more than 90% of Utah, Colorado, Nevada and New Mexico were in some levels of drought.[2] Also in drought conditions were Wyoming, Oregon and Arizona.

Over the course of 2021, conditions improved in the Northeast but worsened in the Western United States. As of June 2021, "nearly the entire region (97 percent) [was] facing abnormally dry conditions."[3] Drought also affected a wide area of Mexico in 2021, as well as the prairies of Canada.

The drought conditions of 2020 were associated with a moderate La Niña episode that had developed in the Pacific Ocean.[4]

By autumn 2020, the drought in the Western States was the worst since similar drought conditions seven years earlier.[5]

The 2020–2021 drought was described by some as possibly the worst drought in modern history for the Western U.S.[6]

By late spring 2021, dry conditions had expanded to almost the entire state of California and to neighboring Nevada.[7]

Midwest

Iowa received widespread rain in September; that improved the dry conditions for the eastern region of the state.[8] But the western half of the state dealt with severe-to-extreme drought problems which extended past 2020 and into 2021. By late April and early May 2021, though, northern, central and northeastern Iowa had fallen back into dry conditions.[9] By mid-August 2021, drought problems in Iowa had worsened; certain areas across the state were affected with extreme drought conditions by August 13. The northwest and east-central regions of Iowa were especially adversely affected with extreme dry conditions by mid-August.[10][11]

The 2020–2022 droughts were also affecting Michigan, southern Wisconsin, most of North Dakota and northwestern South Dakota.[12][13]

In northeastern Illinois near the Chicago metropolitan area, May 2021 was the driest since 2012.[14] As of June 1, 2021, Chicago had only received barely half of one inch of rainfall due to drought in the area.[15] April 2021 was one of the city's driest Aprils on record; only .71 of an inch fell in Chicago in April 2021.[16]

By August 12, 2021, Minnesota was having the worst drought spells since the major drought in the final two years of the late 1980s.[17] Just over seven percent of the state, in particular, nine counties in the northwestern part of Minnesota were having exceptional drought. That was the first time since 1988 the state had been under exceptional dry conditions.[18] The drought conditions in Minnesota during 2021 caused serious comparisons to extremely similar dry conditions eighty-five years prior.[19]

Northeast

By late August/early September 2020, the drought conditions in several regions of the United States had worsened. The New England states and New York were also under severe to extreme drought conditions.[20]

The Northeastern United States were out of drought conditions by the beginning of June 2021.[21]

Southeast

By June 2021, moderate drought conditions had developed in Virginia, North Carolina, South Carolina and Florida.[22]

Mexico

As of April 2021, Mexico was facing one of the most widespread droughts in its history, with 85% of the country experiencing drought conditions.[23]

As of March/April 2022, 30% of Mexico, especially northern, still has serious, critical and major drought problems.[24][25]

Canada

As of Spring 2021, extreme drought threatened the Canadian Prairies in Manitoba and Saskatchewan, after an abnormally dry fall and spring.[26]
