Chicago's Climate
Chicago sits on the shore of Lake Michigan and has a humid continental climate with four sharply defined seasons strongly shaped by the lake. Summers (June to August) are hot and humid, often 27-32°C with thunderstorms and the occasional severe storm, while winters (December to February) are frigid below 0°C with heavy snow and a biting wind that drives the feels-like temperature far lower. Its "Windy City" nickname reflects the gusts sweeping off the lake and plains.
