Upper Midwest

The Upper Midwest is a northern subregion of the U.S. Census Bureau's Midwestern United States. Although the exact boundaries are not uniformly agreed upon, the region is usually defined to include the states of Iowa, Michigan, Minnesota and Wisconsin; some definitions include North Dakota, South Dakota, and parts of Nebraska and Illinois.

The National Centers for Environmental Information considers the Upper Midwest climate region to include Iowa, Michigan, Minnesota, and Wisconsin.[1]


The United States Geological Survey uses two different Upper Midwest regions:


The Association for Institutional Research in the Upper Midwest includes the states of Iowa, Minnesota, North Dakota, South Dakota, Wisconsin and the upper peninsula of Michigan in the region.[3] According to the Library of Congress, the Upper Midwest includes the states of Minnesota, Wisconsin and Michigan.[4]

Climate[edit]

The region has dramatic variations between summer and winter temperatures; summers are hot; and winters are very cold. For example, Sioux Falls averages 25 days each year with temperatures above 90 °F (32 °C) and 45 days each year with temperatures below 5 °F (−15 °C).[5] Mitchell, South Dakota has a record high of 116 °F (47 °C) and a record low of −39 °F (−39 °C).[6]


The growing season is shorter, cooler and drier in areas farther north and west. The region's western boundary is sometimes considered to be determined by where the climate becomes too dry to support growing non-irrigated crops other than small grains or hay grass.
