Are You Ready for Summer Air Pollution?
The Sacramento region's Spare The Air season is underway. Ground-level ozone (also known as smog) is a summer air pollution problem and most of it is caused by mobile sources.
Make a plan to reduce driving when we issue a Spare The Air alert.
Check air quality conditions before you go outside. Smog levels increases throughout the day and will be their highest in late-afternoon or early evening.
Download the free Sacramento Region Air Quality app today. You'll get air pollution readings from monitors throughout the region, the daily forecast, plus Spare The Air alerts.
A Spare The Air alert in the Sacramento region will be issued when the AQI for ground-level ozone pollution is forecast to reach 126 or above.

Air Quality Forecast and Weather Discussion
Saturday and Sunday, cloudy skies, cool temperatures and scattered rain showers will inhibit ozone production. In addition, an upper-level trough of low pressure will enhance vertical mixing, and moderate winds will aid pollutant dispersion. Therefore, ozone levels will be Good on both days. Monday, increasing sunshine and warmer temperatures will enhance ozone formation. However, moderate and gusty onshore winds during the afternoon will keep pollutants dispersed. Thus, ozone levels will remain Good.
