MINNEAPOLIS/ST PAUL, MN (TWIN CITIES)

Overview:
Minneapolis is the largest city in the state of Minnesota, and it forms half of the Twin Cities metropolitan area alongside neighboring city and state capital Saint Paul. The Twin Cities are located on an artesian aquifer at the confluence of the Mississippi and Minnesota Rivers. Water is prevalent in the region, with thirteen lakes found within 5 acres of the Minneapolis city boundaries, in addition to the two major rivers and several wetlands, creeks, and large ponds.

The Twin Cities’ climate is continental, with wide swings in temperature occurring from summer to winter. Summers are warm to hot and often humid. Temperatures in certain areas can spike up to 9°F warmer than neighboring communities due to the urban heat island effect. Winters are cold and snowy, and the region reports the coldest average temperatures of any major metropolitan area in the U.S. Cold arctic air masses are often transported south toward the region during the winter, due to the surrounding flat terrain with no natural barriers to block it. Thunderstorms bringing heavy rainfall are common in the spring, summer, and autumn, with nearly half of annual precipitation typically occurring during the summer months of July to August. Snow is frequent in the winter, with an annual average snowfall of over 54 inches.

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.
