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.
Thursday: Upper level ridging and surface high pressure will continue to dominate the area's weather. Skies will be mostly clear throughout the day. Winds will be southerly at 5-10 mph. PM2.5 and Ozone are both expected to be in the yellow (moderate) range of the AQI.
