The Upper Midwest is a fickle place where, in the winter, we can see literally feet of snow and air temperatures of -10°F., -20°F., -30°F.—or even colder. During the winter of 2025, Ely, Minnesota, recorded an air temperature of -41°F. (not a record), and several places experienced wind chills colder than -50°F. At the other extreme, summer temps often reach into the 90s with heat index levels creeping over 100°F. And no, it is not a "dry heat." The only thing we can do about these wild Midwest temperature swings is try to manage them.
In the winter, we bundle up and cover as much of our skin as possible. In the summer, though, we head for our region's many lakes, rivers, and swimming holes. Fortunately, we have one of the biggest, coolest lakes there is right in our backyard: Lake Superior. It's the largest freshwater lake in the world by surface area, and its average annual water temperature hovers around 43°F. It's a natural cold plunge and air conditioner, combined, and it's where I like to head when the mercury starts to rise. Next time a heat wave is heading for you, why not jump in the car and take a road trip to some of the best beaches, coolest waterfalls, and refreshing swimming holes along Lake Superior and its tributaries—like this three-day, two-night journey through Minnesota, Wisconsin, and Michigan.
