Chicago's weather is notoriously unpredictable. The city experiences all four seasons, and the transition between them can be sudden and extreme. In the winter, temperatures can dip well below freezing, and strong winds off of Lake Michigan make the cold even more biting. Snow is also common, and Chicagoans often have to contend with treacherous ice storms.

Spring brings some relief from the cold, but it can also be a volatile season, with severe thunderstorms bringing high winds and heavy rains. Summer is usually hot and humid, with temperatures often topping 90 degrees. However, the city sometimes gets a reprieve from the heat in the form of a cool lake breeze. Fall is generally mild, but it can be wet, as heavy rains are not uncommon. As a result of the city's unpredictable weather, Chicagoans have to be prepared for anything.
