What August is like in Chicago
August stays warm and busy. Highs near 82F (28C), humid days, and a mix of sun and thunderstorms. The lake is at its warmest all year, which makes this the best month for swimming. Crowds and prices remain at their peak, with Lollapalooza sometimes spilling into early August and the Air and Water Show drawing huge crowds.
This month suits beach lovers and families who want easy summer days and kid-friendly museums. Expect lines and plan ahead. If you can shift to September, you get nearly the same weather and a warm lake with far fewer people.
Make the most of August
What is especially good about Chicago this month.
The warmest lake of the year
The water at North Avenue and Oak Street beaches is as warm as it gets, and calmer too. It is the best month for a swim with kids.
Chicago Air and Water Show
One weekend in August, free air shows roar over the lakefront. North Avenue Beach has the best view, so arrive very early.
Jazz Festival kickoff
The Chicago Jazz Festival runs around Labor Day weekend, so late August trips can catch the start. Shows in Millennium Park are free.
What to pack for August
- A swimsuit, towel, and beach sandals
- Light, breathable clothes
- A small umbrella or rain shell for thunderstorms
- Reef-safe sunscreen and a hat
Our timing tip
If you do not want Air and Water Show crowds, check that weekend's date and plan your beach day for another day, since the lakefront and trains get packed.

Things to do in Chicago
Chicago Architecture Center river cruise
Runs roughly spring through fall. The first and last departures of the day are the most comfortable in summer.
Art Institute of Chicago
One of the great museums anywhere. Go at opening and head straight to the Impressionists before the crowds.
Millennium Park
Cloud Gate (the Bean), Crown Fountain, and free summer concerts at the Pritzker Pavilion. Early morning for photos.
Field Museum
Home of SUE, one of the most complete T. rex skeletons ever found. Plan at least half a day.
Museum of Science and Industry
A real U-boat, a coal mine, and a huge model railroad. Best on weekdays outside school field trip season.
Wrigley Field
A Cubs day game in summer is the classic Chicago afternoon. Tour days run when the team is away.
Beat the crowds
- Check the convention calendar at McCormick Place. Big shows can double hotel rates for a week.
- Buy museum tickets online and arrive at opening. The Field, Shedd, and MSI fill fast on summer weekends and during school breaks.
- Stay in a neighborhood like Lincoln Park, Wicker Park, or the West Loop and ride the L downtown. Rates are often better than the Loop and River North.
- September gives you summer weather with far fewer visitors. It is the best-value warm month.
Know before you go
- Architecture boat tours and many river cruises run roughly spring through fall and pause in winter.
- Beaches are officially open with lifeguards from about Memorial Day to Labor Day. Outside that window, swimming is not supervised.
- Winter never shuts the city down. Museums, theater, and restaurants run full schedules, and the L keeps moving in all but the worst storms.
- Wrigley Field and Sox park tours depend on the baseball schedule; check game days before you plan.
