The Coldest Place in Iowa

Dubuque, located on the Mississippi River in Iowa, is the state’s oldest city and also one of the coldest, with an average annual temperature of 47.2°F. Despite its cold temperatures, Dubuque has many attractions, including the National Mississippi River Museum and Aquarium, as well as an established higher education system with schools like Loras College and Clarke University (both of which are run by the Roman Catholic Archdiocese of Dubuque). At the time of the 2020 census, the population of Dubuque was 59,667. Dubuque is located at the junction of Iowa, Illinois, and Wisconsin, an area locally known as the Tri-State Area. It is generally considered the main commercial, industrial, educational, and cultural center for the region. Interestingly, Dubuque is part of the “Driftless Area,” which is a portion of North America that was not affected by the Wisconsin Glaciation. Places in the Driftless Area were never covered by ice during the last ice age and have geography that uniquely reflects it. Dubuque’s cold temperatures and rich history make it a unique and interesting place to visit. Its location on the Mississippi River and its proximity to Illinois and Wisconsin add to its appeal, making it a popular destination for both tourists and residents.
