BENSON, MN

Overview:
Benson, Minnesota is the county seat of Swift County, located along the banks of the Chippewa River in the western half of the state. The surrounding land is largely flat and agricultural.

The climate in Benson can be described as continental and is influenced by the succession of high and low-pressure systems across the region. With the absence of mountainous terrain to form a natural barrier, warm air masses flow into the region from the Gulf of Mexico and the Pacific coast, while cold air masses flow southward from Canada. Summers are hot and humid, and the western part of the state often experiences the highest temperatures in summer. Snowfall can be heavy during the winter, though not as heavy as in more northern areas in the state.

Annual High and Low Temperature Departure

Cold Temperatures

¹Heating Degree Days (HDDs) are indexed units, not actual days, that roughly describe the demand to heat a building. HDDs accumulate on days colder than 65°F when heating is required. Every degree below 65°F is added to the annual total for an annual HDD value, which is plotted in the figure.

Hot Temperatures

²Cooling Degree Days (CDDs) are indexed units, not actual days, that roughly describe the demand to cool a building. CDDs accumulate on days warmer than 65°F when cooling is required. Every degree above 65°F is added to the annual total for an annual CDD value, which is plotted in the figure.
