Ozone, also known as smog, forms when sunlight causes reactions between nitrogen oxides and volatile organic compounds. Conditions during the summer are favorable for ozone formation. During the Texas ozone-forecast season, roughly March through November, TCEQ meteorologists provide daily ozone forecasts for each of the nine metropolitan areas in Texas. The forecast season is determined by when each region is most likely to experience elevated ozone concentrations. 

Air Quality Indexaqi_scale.jpg

The Air Quality Index is a numerical scale that is used for rating air quality. Ozone, along with other air pollutants, is measured on the AQI scale. The scale is accompanied by corresponding colors that indicate the amount of threat to health posed by the concentration of a pollutant. Not only is the AQI used for reporting current conditions, but it is also used to forecast future conditions. Find the latest forecast for air quality conditions in Texas. 

Ozone Action Day

If TCEQ meteorologists forecast an Ozone Action Day, they will contact the National Weather Service to broadcast the information across its "weather wire." The TCEQ also informs the public typically a day in advance when conditions are forecast to be favorable for high ozone levels so citizens, businesses, and industry can take steps to reduce the pollutants that contribute to ozone formation.
