July Heat Wave Claims Six Lives in Cook County
A severe heat wave in Cook County, Illinois, has resulted in six confirmed deaths, marking the deadliest month for heat-related fatalities in over a decade, according to the Cook County medical examiner’s office. The deaths occurred between June 30 and July 14, 2026, with air temperatures reaching the upper 90s °F (32-37 °C) and heat indices exceeding 100 °F (37.8 °C). Victims ranged in age from 44 to 71, with underlying health conditions such as heart disease, diabetes, and obesity contributing to the fatalities. Experts warn that the true toll may be higher, as heat-related deaths are often misclassified. The National Weather Service reported that the heat index in Chicago reached 100 °F (37.8 °C) on July 14, exacerbating the risk for vulnerable populations.
