My tip for August

Schedule outdoor activities early in the day and keep an indoor backup plan.

How August compares

10th of 12 overall in Chicago, 6th for weather, 11th for space, 11th for value. The emptiest month is January; the best value is January.

Plan around

Lollapalooza: Grant Park and the downtown lakefront get packed for four days; hotel rates hit their yearly peak citywide, not just near the park.

Not set on August?

Chicago’s best weather window — warm days, cool evenings, rooftops back in full swing.

Warm, dry, comfortable days with noticeably thinner crowds and softer rates than midsummer.

Book early and plan around the busiest hours — the rainiest month of the year, on top of peak summer crowds and prices.
