Air Quality Forecast and Ozone Action Day Alerts

Sign up to receive the Today's Texas Air Quality Forecast and/or Ozone Action Day email or text alerts for several metropolitan areas throughout Texas.

The Today's Texas Air Quality Forecast is based on the EPA's Air Quality Index scale for ozone, PM2.5, and PM10, made for 14 forecast regions across the state (Austin, Beaumont-Port Arthur, Brownsville-McAllen, Corpus Christi, Dallas-Fort Worth, El Paso, Houston, Laredo, Lubbock, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen). It is updated daily on normal TCEQ work days and may also be updated on weekends or holidays when air pollution levels are high. The forecast is posted on the Today's Texas Air Quality Forecast webpage and disseminated via e-mail whenever updates are made.

Each day during ozone season (roughly March through November in Texas), Ozone Action Day forecasts are made for nine participating metropolitan areas (Austin, Beaumont-Port Arthur, Corpus Christi, Dallas-Fort Worth, El Paso, Houston, San Antonio, Tyler-Longview, and Victoria). TCEQ informs the public typically a day in advance when conditions are forecast to be favorable for high ozone levels in any of the participating areas so citizens, businesses, and industry can take steps to reduce the pollutants that contribute to ozone formation. For more information on the Ozone Action Day forecast program, a list of the individual areas' official ozone season dates, and ozone in general, see Ozone: The Facts.
