Do You Know Current Air Pollution Levels?
Check air quality conditions before you go outside to help protect your health. 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.

Mark your calendar for May 1, when the Sacramento region's Spare The Air Program will begin. From May 1 to October 31 each year, when the AQI is forecast to reach 126 or higher for ground-level ozone a Spare The Air alert is issued. On Spare The Air days, residents are asked to reduce their driving.

Air Quality Forecast and Weather Discussion
Friday, an offshore trough of low pressure aloft will enhance atmospheric mixing over northern California. In addition, moderate onshore winds will aid dispersion and transport clean air into the Sacramento Valley throughout the day. Therefore, particle levels will be Good. Saturday, as the trough moves inland over central California, it will continue to promote atmospheric mixing. Therefore, despite decreasing southerly winds hindering dispersion, particle levels will remain Good. Sunday, moderate southeasterly winds will disperse pollutants as the area of low pressure gradually departs to the east. Furthermore, cool temperatures aloft will support atmospheric mixing, keeping particle levels high-Good.
