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.
Tuesday-Friday: Upper level ridging and surface high pressure will dominate the area's weather on Tuesday and Wednesday to provide mostly sunny skies. The ridge will flatten and the high will move away from the area on Thursday and Friday. This will lead to an increase in clouds with a very low chance for rain. Winds each day will be southerly at 5-15 mph. Temperatures will be above normal in the 70s each day. PM2.5 is expected to be in the green range on Tuesday and in the yellow range on Wednesday through Friday.
