Weather

They don't call it the 'Windy City' for nothin'. There's everything from cool, God-sent lake breezes at the height of summer to skirt-raising gusts in the spring to spine-chilling, nose-chiselling blasts of icy air in the winter. Late spring and early autumn are pleasant, being generally warm, clear and dry. July and August can get really hot, with temperatures from 27-32°C (80-90°F) and high humidity. Winters can be damp and cold - between -11°C and -2°C (12°F and 29°F) if you're lucky - and snowy for days on end.
