The Air Quality Index (AQI) is the daily forecast for the quality of the air. In many metropolitan areas the AQI is reported during the weather report. Air quality is the worst during the summer months and days that are hot are often bad air quality days too. The AQI is color coded. Many areas delcare an Air Quality Action Day on days when the forecast is Orange or worse.
