Chicago, Illinois – Dangerous swim conditions continue along southern Lake Michigan beaches through Thursday morning, with the National Weather Service urging residents and visitors to stay out of the water. Waves reaching 3 to 6 feet are expected to create life-threatening rip currents and hazardous boating conditions from Chicago to Indiana’s shoreline.
According to the National Weather Service in Chicago, all southern Lake Michigan beaches face a high swim risk until Thursday morning. Officials advise avoiding piers, breakwalls, and lakeshore trails due to dangerous surf. Signs and closures will remain in effect as waves peak and boating risks increase.
Beyond the shoreline, drivers in northern Illinois should prepare for patchy morning fog, especially in rural areas and low-lying spots. The fog will reduce visibility just after sunrise, prompting warnings for slower travel, low-beam headlights, and extra caution on bridges and valleys.
While dangerous conditions grip the lakefront, inland areas can expect a stretch of calmer, drier weather with highs in the low 80s Thursday and Friday before a cooler breeze settles in by Sunday.
Warnings for rip currents and hazardous waves remain active until Thursday morning, with additional updates expected if conditions worsen.
