As summer temperatures soar into the high 90s with triple-digit heat indexes, Chicagoans find themselves in the grip of another relentless heat wave. The National Weather Service has issued excessive heat warnings for Cook County through the weekend, urging residents to take precautions against heat-related illness. In a city where brick buildings trap warmth and Lake Michigan’s breeze can offer only so much relief, staying cool isn’t just a comfort—it’s a necessity.
Here are the best ways to keep your cool, whether you’re out and about or hunkering down at home.
Head to a Cooling Center
Chicago has opened more than a dozen cooling centers across the city. These include libraries, community service centers, senior centers, and park district fieldhouses. Most are open from 9 a.m. to 5 p.m., with extended hours during severe heat.

Use Public Libraries and Park District Pools
Libraries aren’t just for books—they’re air-conditioned havens during the worst of the heat. Several Chicago Public Library branches are also designated as official cooling centers.
And if you’re looking to beat the heat more actively, the Chicago Park District has more than 50 outdoor pools and over a dozen splash pads open for summer. Admission is free. Bring sunscreen and hydrate often.
Stay Indoors During Peak Heat
Between 11 a.m. and 4 p.m., the city streets radiate heat like stovetops. If possible, limit outdoor activity during these hours. Postpone strenuous tasks like mowing the lawn or walking long distances until early morning or late evening.
If you must be outside, wear light-colored, loose-fitting clothing, a wide-brimmed hat, and use sunscreen.
Keep Your Home Cool Without Breaking the Bank
Window units and central AC are working overtime, but not every Chicagoan has access—or can afford—to keep them running all day. Try these tips:
- Close blinds and curtains to block out the sun.
- Use fans wisely—ceiling fans should spin counter-clockwise in summer to push cooler air down.
- Unplug electronics when not in use. Even idle chargers generate heat.
- Sleep low—heat rises, so the lowest floor in your home may offer relief at night.
Stay Hydrated and Eat Smart
During a heat wave, your body loses water faster than usual. Drink water even before you feel thirsty. Avoid alcohol and caffeine, which can dehydrate you.
Stick to lighter meals. Salads, fruits, and cold sandwiches not only keep you cool, but also reduce the need to turn on the oven or stove.
Check on Neighbors and the Vulnerable
Chicago has a painful history with heat waves. The deadly summer of 1995 claimed over 700 lives, many of them elderly residents living alone. Authorities urge everyone to check in on neighbors, especially seniors, those with medical conditions, and anyone without access to air conditioning.
“Staying cool is a community effort,” says Dr. Elena Castillo, an ER physician at Northwestern Memorial Hospital. “Even a simple phone call or knock on the door can save a life.”
Cool Down Creatively
Think outside the box: wet a towel and drape it over your shoulders, take a cool foot bath, or freeze water bottles and place them near fans to circulate cold air. Some Chicagoans are even heading to local movie theaters for matinees—not just for entertainment, but for the AC.
In Case of Emergency
Heat stroke is a medical emergency. Symptoms include confusion, rapid pulse, flushed skin, and lack of sweating. Call 911 immediately if you suspect someone is suffering from heat-related illness.
As the city bakes, one thing remains true: Chicagoans are resourceful. With a mix of smart planning, neighborly care, and a bit of Midwestern grit, the city will ride out the heat wave—together.
Stay cool, Chicago.
