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.
Saturday-Monday: Upper level ridging will move on top of the area with surface high pressure stretching down from the NE US. Each day of the forecast period will be mostly sunny with no rain and light winds. Both PM2.5 and Ozone are expected to be in the yellow range (moderate) of the AQI through Monday.
