The climate of South Dakota (United States of America)
The state of South Dakota is located on the Great Plains which is a large region consisting of prairies, steppes and grass lands east of the Rocky Mountains. South Dakota is divided into two parts by the Missouri River which flows from north to south through the state. Locals often use the terms ‘East River’ and West River’ to point out where a city is located in the state. Seven Indian Reservations are situated in South Dakota. After the states of Alaska and New Mexico South Dakota is home to the most Indians in the United States. A world famous monument in South Dakota is Mount Rushmore. Mount Rushmore features sculptures of the four first presidents of the United States of America and is one of the best known attractions in the United States.

South Dakota has two different climate types. The total amount of annual precipitation determines which climate type applies to a certain region. In general the eastern part of the state has a moderate continental climate and the western part of the state has a cold steppe climate (type BSk according to the Köppen climate classification). Winters are cold in South Dakota. Extremely low temperatures are not uncommon, especially when cold air is supplied form the Arctic. A short spring is followed up by a warm summer. For three months daytime temperatures reach tropical values. However, during the night temperatures may drop. In June there may be a difference between daytime and night time temperatures of 20 degrees. Extremes in weather such as fierce winds, heavy thunderstorms, snow storms, ice rains and tornadoes are not uncommon in South Dakota. South Dakota is located in Tornado Alley which is a large region in which tornadoes are not uncommon.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The figures below apply to Nashville.
