Air quality forecasts for Evansville and Vanderburgh County are provided as a public service.  They are best estimates of predicted pollution levels that can be used as a guide so people can modify their activities and reduce their exposure to air quality conditions that may affect their health.  The forecasts are routinely made available at least a day in advance, and are posted by 10:30 AM Evansville time on Monday (for Tuesday through Thursday) and Thursday (for Friday through Monday).  When atmospheric conditions are uncertain or favor pollution levels above the National Ambient Air Quality Standards, forecasts are made on a daily basis.

Ozone forecasts are available from mid-April through September 30th.  Fine particulate (PM2.5) forecasts are available year round.
