Air Quality Advisory for Sunday August 3, 2025, through Monday August 4, 2025 The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Advisory for elevated levels of fine particulate (PM2.5) across the state of Michigan. Pollutants are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range with some areas reaching Unhealthy (Red AQI) range. The Air Quality Advisory includes all Michigan counties Wildfire smoke looks to persist throughout Michigan through at least Monday as winds shift, although it stays rather light. Overall hourly concentrations look to diminish but still stay in the USG range, therefore above our Advisory criteria. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes. Reduce or eliminate activities that contribute to air pollution, such as: outdoor burning; use of residential wood burning devices. Tips for households: Keep windows closed overnight to prevent smoke from getting indoors and, if possible, run central air conditioning with MERV-13 or higher rated filters.
