It gets just a hair colder on average in Duluth, Minn., where the 30-year-average daily low temperature is 30.5 degrees. Hovering around freezing for most of the year doesn’t stop residents from enjoying outdoor activities such as ice fishing, ice kiting and even wintertime surfing. Surfers can be spotted on Lake Superior in sub-zero temperatures so cold that icicles form on their wetsuits.
