Summary

  • Chicago's air quality reached hazardous levels Thursday — the worst in the city's recorded history, according to Mayor Brandon Johnson — as wildfire smoke from more than 200 fires burning in northwestern Ontario settled over the region.
  • The Air Quality Index climbed above 400 during the day before peaking at 700 Thursday evening. Chicago was ranked the worst major city in the world for air quality at its peak.
  • As of Friday morning, Chicago's AQI remains above 400 — still in the "hazardous" category. An Air Quality Alert is in effect for 12 Illinois counties including Cook, DuPage, Kane, Will, and Lake until midnight Friday.
  • Smoke is expected to begin clearing later Friday afternoon as winds shift, with conditions improving to the "unhealthy" category by Friday evening and "moderate" by Saturday morning.
  • Light to moderate smoke could return Saturday evening around 8-9 p.m. as winds shift, though not as severe as Thursday.
  • City officials continue to urge residents to stay indoors, keep windows closed, and limit outdoor activity until the AQI drops.
  • Anyone with heart or lung conditions, young children, senior citizens, and other sensitive groups should avoid all unnecessary time outside. If you must go outside, wear a well-fitted N95 or KN95 mask.
  • For real-time local conditions, check AirNow.gov. Residents can sign up for city emergency alerts through the OEMC app or at notifychicago.org, and anyone needing air-conditioned relief can call 311 to find a cooling center or request a well-being check for an at-risk neighbor.

Those most at risk—older adults, children, pregnant people, and anyone with heart or lung conditions—should avoid all unnecessary time outdoors. The Chicago Park District has closed beaches and moved or canceled outdoor programs.

Residents are advised to stay inside as much as possible, keep windows closed, run air conditioning on recirculate to keep smoky air out, and run an air purifier on its highest setting if available. Anyone who must go outside should wear a well-fitted N95 or KN95 mask, though health officials stress that a mask is not a substitute for staying indoors. Watch for symptoms like coughing, chest pain, or difficulty breathing, and call 911 for severe symptoms.

The National Weather Service has extended its air quality alert through Friday night for parts of northern Illinois and all of northwest Indiana.

The air quality index climbed above 450 during the day Thursday, ranking Chicago among the worst major cities in the world. It then jumped to over 600 on Thursday evening.
