Chicago, Illinois Weather in April

April feels changeable

Chicago in April is cool and often damp. Days reach about 10°C, while evenings fall to 4°C. Rain comes on around 12 days, and clouds are common, so don't count on a full day of sunshine. The lakefront can feel colder than downtown, especially when the wind picks up.

There's enough daylight for sightseeing, but the weather suits indoor stops mixed with short walks. See the Art Institute of Chicago, then stroll through Millennium Park when the skies clear. Save long lakefront walks or a beach day for warmer weather.

Events and quieter streets

April brings the Chicago Latino Film Festival, with screenings around the city. The Cubs' baseball season also gets going at Wrigley Field; a game is a fun way to see the lively Wrigleyville area, though chilly seats can test your patience.

Families who enjoy museums and baseball will find plenty to do between showers. April is generally quieter and less expensive than the busy summer months, though Cubs games and festival screenings draw their own crowds. Spring break and Easter can make some days busier, depending on when they fall.

A handy rainy-day route

April is a shoulder-season month: you'll usually find fewer summer visitors, but the weather can limit outdoor plans. May is warmer, though it's also wetter by the monthly rainfall total. Keep a flexible day in mind rather than building your whole visit around the lake.

For a weather-proof city view, ride the CTA Brown Line around the Loop. You'll pass above downtown streets and see the tall buildings without committing to a long walk in the rain. For dinner nearby, try a Chicago-style hot dog—just don't ask for ketchup.
