Air Quality Forecast

Air quality forecasts are issued every day of the year for the Birmingham area and are based on the Air Quality Index (AQI).  The AQI is a color-coded scale that reports how clean or polluted the air is and the associated health effects.

The Jefferson County Department of Health forecasts fine particles (PM2.5) year-round and the Alabama Department of Environmental Management forecasts Ozone (O3) during the warm season.

An Air Quality Alert is issued when the AQI is forecast to reach 101 or higher.  The public is encouraged to decrease their personal emissions on days with higher pollution levels.
