Chicago, Illinois – Swimmers and beachgoers across Chicago and northern Illinois are facing dangerous conditions Thursday night into Friday, as hazardous waves and strong rip currents threaten Lake Michigan beaches and an air quality alert blankets the region.
According to the National Weather Service Chicago and the Illinois EPA, a Beach Hazards Statement and an Air Quality Alert are both in effect through at least 4:00 PM Friday, August 1. Northeast winds are fueling high waves and choppy waters from Winthrop Harbor to Indiana’s Porter County, with swimming conditions described as life-threatening—especially for inexperienced swimmers. In addition, an Air Pollution Action Day has been declared for all of Illinois due to wildfire smoke and elevated ozone, pushing air quality into the “Unhealthy for Sensitive Groups” range.
Local impacts include widespread haze, dangerous swimming at Chicago and Indiana beaches, and reduced air quality in cities like Evanston, Oak Lawn, Naperville, and Gary. Residents are urged to stay out of the water, avoid piers and breakwalls, and limit outdoor activity—especially if you have asthma or respiratory issues. Area schools and day camps may restrict recess and outdoor activities.
Similar summer beach hazards have resulted in numerous rescues in past years. This dual threat will persist through Friday afternoon, with updates and additional warnings possible.
More advisories may be issued as weather and air quality conditions evolve. Stay tuned for the latest updates.

- Friday: Haze early, mostly sunny, high 73°F. Dangerous swimming, unhealthy air until 4 PM.
