Ozone season has arrived
March 03, 2026
March has many of us thinking about Spring, but that also means Ozone season is here. Ozone season began March 1 and runs through the end of October.
Air Quality Division meteorologists at the Michigan Department of Environment, Great Lakes, and Energy (EGLE) keep their eyes on the skies year-round and continue to forecast air quality related issues.
EGLE meteorologists will issue advisories or alerts when weather conditions may cause air to be unhealthy for some individuals. On these days, people are encouraged to change their activities to minimize their exposure.
Alerts or advisories are called when levels of ozone or particulate matter put people at risk. During ozone season, high levels of ozone near the ground can have harmful effects for sensitive individuals.
Meteorologists will issue an Air Quality Alert when levels of pollutants may be unhealthy for the public. It is important to know how to protect yourself and your loved ones when air quality is unhealthy by checking the Air Quality Index (AQI) on your favorite weather app or the MiAir dashboard.
