Chicago experiences one of the most dramatic seasonal transformations of any major U.S. city, with temperature swings that can exceed 100 degrees between winter and summer. The Windy City can plunge to -20°F in January and soar above 95°F in July, making timing your visit crucial for the experience you desire. This remarkable climate variability is precisely what gives Chicago its distinct character throughout the year, with each season offering its own unique charm and activities.
Getting to Chicago
Chicago is served by two major airports: O’Hare International Airport (ORD), one of the busiest airports in the world, and Midway International Airport (MDW), which primarily handles domestic flights. Both airports offer excellent connections to the city center via the Chicago Transit Authority (CTA) trains, known locally as the ‘L’.
If you’re traveling from within the Midwest, Amtrak trains and intercity buses provide convenient alternatives to flying. Chicago’s Union Station serves as a major rail hub connecting to cities across the United States.
