The most notable body of water in Illinois is Lake Michigan, which experiences a wide range of water temperatures. During the summer months, the water temperature along the lake’s southern shore typically reaches between 70°F and 75°F (21°C to 24°C), providing a comfortable environment for swimming and other water activities.
