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: Surface high pressure will be in control of the area's weather and will create clear skies throughout the day. Winds will predominately be from the west to northwest at 5-10 mph. Temperatures will rise to the upper 70s. Both PM2.5 and Ozone are expected to be in the green (good) range of the AQI.
Friday: Surface high pressure will continue to stretch into the area from the north. This will continue the mostly clear skies throughout the day. Winds will be 5-10 mph from the northeast. High temperatures will be in the mid 70s. PM2.5 is expected to be in the yellow range.
