Chicago's weather is known for its dramatic swings and four distinct seasons. Summers are warm and humid, often reaching the 80s and 90s Fahrenheit, with occasional thunderstorms. Winters are cold and snowy, with temperatures frequently dipping below freezing and significant snowfall. Spring and fall offer milder temperatures but can be unpredictable, with sudden shifts between warm and cool conditions. Lake Michigan plays a significant role, moderating temperatures near the lakefront but also contributing to lake-effect snow in winter.
