May. Many birds pass through canoe country on their way north for the summer. Some stay to nest and decorate the tree with their beautiful colors. Wildflowers begin to poke through the forest floor almost as soon as the snow is gone. Fishing season opens around mid-May for trout, northern pike, and walleye. Bass fishing seems to pick up later.
Trout are in shallow water and easily caught in the first part of the season.
Weather is very unpredictable early in the season. Nights can be very cool, and freezing temperatures are possible. Daytime highs vary but can range from the 50s to the 80s, averaging 62 degrees. Bugs are generally not out early in the month and not bad toward the end. This is a very low-use time, with the exception of Memorial Day weekend.
