Camping on one of the eight state parks and several private campgrounds on Lake Superior is great! Be prepared for cooler temperatures along the lake. Superior is large enough to create a micro-climate around it. Just getting a couple hundred feet away from the lake may increase the daytime temp but 5 degrees. Another extreme example. I’ve seen summer daytime temps on the harbor in Duluth to be in the upper 60’s while the temp at the Duluth airport 7 or 8 miles away to be in the mid 80’s! Remember: You are located at about 47 degrees north latitude and near a very large, deep, cold lake.
