FAQs about flying to Chicago

Chicago climate

Chicago has an extreme climate with very hot summers and bitterly cold winters, its lakeside setting only slightly moderating the temperatures and adding some humidity to the atmosphere. Chicago has distinct seasons, with a short spring, when temperatures are moderate and nights frosty. Summers are hot, sunny and humid, from June to the end of September, with cool evenings when breezes blow in from Lake Michigan. Autumn is a lovely time of year when the air is crisp and cool, with blue skies and sunshine. Winters in Chicago are icy and prone to cold, harsh winds. Snow is common, and it is also very rainy during the winter months.

Getting around Chicago

No need to worry about getting around Chicago. There are plenty of ways to get around. Hop on the El, short for elevated train, the city’s subway system, or one of the buses that runs all over the city. For information about fares and routes, check out the website for the Chicago Transit Authority. Traffic is often congested, especially during rush hour, and driving isn’t recommended. Biking is becoming increasingly popular around the city, thanks to the city’s former mayor encouraging residents to ride their bikes as a mode of transportation. With all of Chicago’s lakefront property, biking can be a great way to enjoy the city.
