CHICAGO — The Chicago area is under an extreme heat warning as the city faces its first major heat wave of 2025, with a heat index peaking at 106 degrees on Saturday and dangerously high temperatures expected to continue into Monday, according to the National Weather Service.
High Temperatures, Higher Risks
Saturday’s actual high was 96 degrees, but humidity levels pushed the heat index to 103–106, prompting public health officials to warn residents to limit outdoor activity and remain in air-conditioned environments when possible.
“This heat can be life-threatening, especially for older adults, young children, and people with chronic health issues,” the National Weather Service said in its alert.
Cooling Centers Activated Across Chicago
In response, the city has opened designated cooling centers and extended hours at select public libraries and park district buildings to provide relief for vulnerable residents. A full list of locations is available through the city’s 311 service.
Officials are urging residents to check on neighbors, avoid strenuous outdoor work, and stay hydrated.
“Use fans, seek shade, and wear lightweight clothing,” said Dr. Allison Arwady, Chicago’s former public health commissioner. “This kind of weather can become deadly very quickly, even for healthy individuals.”
Events Continue Despite Scorching Conditions
Despite the sweltering heat, thousands turned out for Chicago’s Pride Fest, which kicked off over the weekend. Many attendees came prepared with umbrellas, parasols, water bottles, and cooling neck wraps to beat the oppressive weather.
Among them was Aurora Burton, who traveled from Michigan for the celebration. “It’s hot, but we’re here for community,” she said while shielding herself with a parasol. “We’re just being smart and taking breaks.”
Emergency Services on Alert
Chicago’s emergency services remain on high alert as calls for heat-related illnesses typically surge during extreme weather events. First responders are monitoring vulnerable areas and unhoused populations to provide water and transport to cooling sites if needed.
The Warning Stays In Place
The extreme heat warning remains in effect through Monday evening, with overnight lows not expected to provide much relief, staying in the upper 70s. Sunday and Monday are forecast to remain in the 90s, with persistent high humidity.
“It’s important to listen to your body,” said a spokesperson for the National Weather Service. “If you feel dizzy, weak, or confused, seek medical help immediately. This is not just uncomfortable weather — it’s dangerous.”
