National Weather Service in Chicago Issues Excessive Heat Watch Beginning Wednesday

August 21, 2023

The City of Chicago will open additional Cooling Centers along with Safety Tips and City Resources to Beat the Heat and to Stay Safe


An Excessive Heat Watch has been issued beginning Wednesday morning, August 23 through 8 p.m. on Thursday, August 24 due to an expected period of dangerous heat and humidity with possible heat index values of 110˚ degrees. Because the heat index is expected to exceed 105°-110°F for at least two consecutive days, in response the City of Chicago will open additional cooling centers for residents to escape the dangerous heat. The Chicago Office of Emergency Management and Communications (OEMC) will continue to monitor conditions with the National Weather Service in Chicago and will issue alerts for additional advisories, watches, and warnings.


Dangerous Heat and Humidity



Excessive heat or extreme conditions can lead to unhealthy impacts – especially over a duration of time. Public safety is the top priority of the City of Chicago and residents are also reminded that hot temperatures and high humidity may cause heat illnesses to occur. OEMC and city departments are reminding residents and visitors of the resources available to help alleviate the effects so everyone can stay healthy and safe.

When the temperatures climb to extreme levels, Chicagoans should monitor themselves and others for the telltale signs of heat-related illness. Extreme sweating, intense thirst, nausea, fatigue or weakness, and dizziness or confusion can all be indicators of heat exhaustion or heat stroke. It’s also important to check on relatives, neighbors, seniors, and our vulnerable population. If you are unable to make contact, you can request a well-being check by downloading the CHI311 app, visiting, or calling 3-1-1. If there is a medical emergency due to a heat-related illness, call 9-1-1.
