Chicago July 2026 heat wave
Entities: Chicago, Illinois · ABC7 Weather · Tracy Butler
Overview
In early July 2026, Cook County, Illinois recorded six heat‑related deaths, the deadliest July heat episode in the area since 2015. Temperatures peaked between 88 °F and 95 °F, and officials cited limited air‑conditioning access, urban heat‑island effects and social isolation as contributing factors.
A few days later, on July 27, an extreme‑heat advisory and warning were issued for Chicago and surrounding counties, with heat‑index values projected above 110 °F in some locations. The city expanded cooling‑center operations at parks, libraries and senior centers and urged residents to request wellbeing checks, aiming to protect vulnerable populations amid the ongoing heat wave.
