The Sacramento Region's Spare The Air Season Is Underway
The Sacramento region’s annual Spare The Air season will continue through October 31. During this time, a Spare The Air alert will be issued when the AQI for ground-level ozone is forecast to be 126 or above.

Residents in the region are encouraged to continue to telework, take transit, drive a hybrid or electric vehicle, or consider active transportation options such as walking, biking, or riding a scooter when possible, to help continue to improve air quality in the region.

Exposure to high air pollution levels can cause immediate and severe health issues including respiratory illness, heart and lung stress, and damaged respiratory cells. Some individuals are more vulnerable to the health impacts of air pollution, including children, pregnant women, the elderly, and individuals with heart or lung conditions, such as asthma.

Air Quality Forecast and Weather Discussion
Saturday and Sunday, an upper-level low pressure system will move across the region, enhancing vertical mixing and dispersion. Furthermore, cooler temperatures and partly cloudy skies will hinder ozone formation, resulting in Good ozone levels on both days. Monday, as the upper-level low departs northern California, mixing will decrease. Additionally, mostly sunny skies and warmer temperatures will aid ozone development. These conditions will yield low-Moderate ozone levels.
