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.
