Understand your air
A higher US Air Quality Index means more polluted air. The good category runs from 0 to 50; the category determines the guidance shown here.
Particles up to 2.5 micrometers across. Their concentration is measured in µg/m³, a different unit from AQI.
Particles up to 10 micrometers across, including dust. Compare like-for-like pollutants and time periods when exploring trends.
The displayed AQI is 26, in the good air quality category. This selects the guidance above. Forecasts show how that index may change; they do not establish which source caused the pollution.
