Chicago, Illinois – Dangerous swimming conditions are set to arrive along Lake Michigan beaches beginning Friday morning, bringing an increased risk of rip currents and high waves for the Chicago area and surrounding lakeshore communities.
According to the National Weather Service in Chicago, winds shifting off the lake will create hazardous surf from early Friday through at least Saturday, with waves expected to build to 4–7 feet. Beachgoers in Cook, Lake, and Porter counties are urged to avoid swimming, especially at popular spots such as Oak Street Beach and Indiana Dunes.
Officials warn that rip currents could quickly sweep even experienced swimmers away from shore. Local agencies will post red flags and may restrict beach access if conditions worsen. The NWS recommends staying out of the water, monitoring lifeguard instructions, and avoiding piers or breakwalls during the high surf period.
These lake hazards coincide with humid summer weather and periodic thunderstorms moving through Illinois, potentially drawing more residents to beaches. Lifeguards and emergency crews are on alert as conditions could be similar to late-June events when multiple rescues occurred.
Dangerous surf is expected to persist into Saturday before gradually improving. More updates and advisories may follow if threats continue.
