Extreme variability

Chicago experiences substantial seasonal variation in both the amount and types of precipitation and clouds. This is a threat to both food security and public health. The extreme weather events that occur may be increasing in frequency. These are called heat waves and high temperature events.

The bulk of the snowfall in Chicago comes in January and February. However, lighter snowfall can come in early October or early May.

The city’s weather is affected by Lake Michigan. The large thermal mass of the lake moderates temperature and suppresses precipitation. When north or northeast winds blow, they cause lake-effect snows. These snows help boost storm systems.
