The Illinois climate can be fairly extreme. The summer months can see temperatures of between 80°F and 90°F (27-32°C) with high humidity, while in winter it can often be damp and cold, with temperatures ranging between 12°F and 29°F (-11°C and -2°C). Regular snow is accompanied by icy winds that whip off Lake Michigan. Travel to Illinois is best embarked upon in May and September, as these are the most pleasant months with reliably warm weather.
