Air quality advisory issued for much of Wisconsin due to wildfire smoke

Metro Wire Staff

CENTRAL WISCONSIN – The Wisconsin Department of Natural Resources has issued a red-level air quality advisory for fine particulate matter (PM2.5) across much of the state, in effect from noon Wednesday through noon Thursday.

The advisory covers more than 40 counties in southern and eastern Wisconsin, including Milwaukee, Dane, Brown, Outagamie, and Kenosha counties. Air quality is expected to reach unhealthy levels in eastern regions near Green Bay and Lake Michigan, while areas farther west may experience conditions considered unhealthy for sensitive groups.

While cleaner air is expected to move in from the northwest, the DNR said wildfire smoke will continue to impact surface air quality through at least midday Thursday.

The advisory urges sensitive groups—including children, older adults, and individuals with heart or lung conditions—to limit or reschedule outdoor activities and remain indoors if symptoms develop.

Those with asthma are advised to follow their action plans and have quick-relief medicine on hand. People with heart conditions should monitor for symptoms such as palpitations, shortness of breath, or unusual fatigue and seek medical attention if symptoms occur.

All residents are encouraged to keep outdoor activity brief and less intense, and to move indoors if they experience breathing difficulties or other symptoms.

To protect yourself during wildfire smoke events, the DNR recommends:

  • Checking the local air quality index.

  • Using the Wisconsin Data Map for real-time conditions.

  • Downloading the free WisconsinAQM app for mobile air quality alerts.

  • Signing up for air quality advisory notices via email or text.

  • Staying indoors, closing windows and doors, and avoiding activities that increase indoor pollution, such as vacuuming or burning candles.

  • Using high-efficiency air filters inside the home.

  • Wearing an N95 mask if prolonged outdoor activity is unavoidable.
