Chicago winters are marked by cold temperatures, often dipping below freezing. Snowfall is typical, with the city receiving an average of 36 inches (91 cm) of snow annually.

Spring: Transition and Unpredictability
Spring in Chicago is a period of transition, with temperatures gradually rising. Early spring can still feel quite chilly, especially in March and April, with occasional snowfall. By late spring, temperatures stabilize and become more pleasant, with blooming flowers and increased sunshine making it a popular time for outdoor activities.

How Lake Michigan Influences Chicago's Weather
Lake Michigan plays a significant role in shaping Chicago's climate. It helps moderate temperature extremes, keeping summers slightly cooler and winters milder compared to inland areas. However, it also contributes to lake-effect snow in the winter and breezes during the summer, making the weather feel more dynamic and sometimes unpredictable.
