Chicago, Illinois – Beachgoers in the Chicago area should be cautious Monday as the National Weather Service warns of a high swim risk at Lake Michigan beaches, with scattered thunderstorms and strong currents possible through Friday.
According to the National Weather Service in Chicago, seasonable summer temperatures will dominate this week, ranging from the low 80s to near 90°F. Spotty showers and isolated thunderstorms are possible each afternoon, with the best chance for more widespread rainfall arriving Friday. Rain chances range from 10% to 50% depending on the day and location, with locally heavy downpours possible.
Cities across northern and central Illinois, including Aurora, Rockford, and Joliet, could see brief rain delays during the late afternoon commute. Temperatures will be slightly cooler near the lakeshore, with increased humidity adding to the discomfort inland. Residents are urged to avoid swimming at unguarded beaches, especially during red flag warnings. Dangerous rip currents and wave conditions could persist into Tuesday.
