In October, Chicago averages a high of 62°F (17°C) and a low of 45°F (7°C). Most runs feel like about 54°F (12°C) once you factor in a typical morning or evening start, so dress for that number rather than the thermometer. Lakefront wind and big seasonal swings make dressing right a real skill in Chicago.
