When to Go
Summer is the most popular time to visit the Midwest and the Great Lakes. Prices in most places peak in July and August. Daily temperatures average in the 70s in Michigan, though July and August heat waves can push them high into the 80s. Depending on the weather, the leaves usually begin to turn in mid-September and reach their most colorful by mid-October. In winter Michigan has the only significant downhill skiing in the region. The Midwest usually gets at least one subzero cold snap every year. For the rest of winter expect temperatures in the 10s and 20s.
