Saint Paul Weather in March

Saint Paul is Minneapolis's twin city on the Mississippi River, the state capital, and home to the famous Winter Carnival celebrating rather than suffering through the extreme cold. The Mississippi River valley location means significant river fog and cold air pooling in the valley while the bluffs above stay clearer. St. Paul gets slightly colder winters than Minneapolis due to its more eastern and valley-bottom position.

Shoulder season — often good value with pleasant weather.
