Chicago is facing a prolonged period of intense heat and humidity. This isn't just a one-day event; the heat is expected to stick around through Monday. The National Weather Service has issued an extreme heat warning for Cook County. This means that the city will experience temperatures soaring into the 90s, with the heat index making it feel even hotter. The heat index is a measure of how hot it actually feels outside, taking into account both temperature and humidity. On Sunday, the high is expected to hit around 94 degrees, but it will feel like 101 degrees due to the humidity. Even at night, temperatures will only drop to 78 degrees, with wind gusts up to 25 mph. This persistent heat is due to the "urban heat island effect, " where concrete and asphalt in the city absorb and radiate heat, making urban areas warmer than rural ones.

This extended heatwave poses significant health risks, especially for the elderly and those with existing medical conditions. Heat-related illnesses can develop quickly in such conditions. Experts advise wearing light, breathable clothing and avoiding strenuous activities during the hottest parts of the day. Staying indoors with air conditioning is the best way to beat the heat. If you must go outside, take frequent breaks and stay hydrated. Check on vulnerable friends, family, or neighbors to ensure they are coping with the heat. Pets also need special care during this time. Keep them indoors as much as possible and ensure they have plenty of water. While this heatwave is earlier than usual, it is not unheard of for Chicago. The city has experienced similar conditions in the past, with the record high for June 22 being 97 degrees set in 1988.

Finding relief from the heat can be challenging, especially since many cooling shelters are not open on the weekend. However, residents can find respite in public libraries, City Colleges of Chicago campuses, Chicago Park District field houses, and splash pads. The Garfield Community Service Center will also be open on Sunday from 9 a. m. to 5 p. m. Over the past three years, Chicago has seen 485 heat-related deaths and more than 700 emergency room visits due to heat. Certain ZIP codes, such as 60620, 60623, 60628, and 60651, have historically seen more heat-related emergencies. This data highlights the importance of taking the heat warning seriously and taking steps to stay safe. By Saturday afternoon, the heat index had already reached 103 degrees in Chicago and 107 degrees in Aurora. Despite the heat, many residents found ways to enjoy the day, such as swimming and lounging at Kathy Osterman Beach. Friends Lyndee Boyce and Chloe Wesley chose to swim during the hottest part of the day, taking precautions to avoid sunburn by staying in the water and using sunscreen.
