What’s the weather like in Chicago in March?

Located in the state of Illinois on the shores of Lake Michigan, Chicago has a humid continental climate. Often known as the ‘Windy City’, Chicago’s weather can be very unpredictable, especially in March which falls between the winter and summer seasons. This time of year is often very cold and damp in the city and surrounding areas, so you’ll need to pack lots of warm layers.


In March, the average temperature in Chicago is a chilly 3°C, with highs of 8°C and lows dipping below freezing to -2°C at night. With such cold temperatures, make sure you bring a hat, scarf and gloves to stay warm, especially after dark. Around 70mm of rain is expected this month, but with half of all days in March forecast to be sunny, you’ll still see bright weather on your visit to the city in March.
