The predominant climate in the U.S. Great Plains is a steppe (semi-arid) climate.

The semi-arid climate of the Great Plains, which stretches from the Dakotas to Texas, is marked by little to moderate precipitation. Although it lacks the high moisture content of more humid locations, this climate is not dry enough to be classified as a desert. Because of this, grasses and bushes predominate in the landscape, with sporadic droughts. The area is good for agriculture, especially crops like wheat, however, irrigation is frequently required due to the region's hot summers and severe winters. A unique, open prairie environment is produced by the steppe climate.
