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
Tuesday, light and variable morning winds will allow pollutants to accumulate, while a morning inversion hinders low-level mixing. However, moderate onshore winds will develop in the afternoon and early evening, dispersing pollutants and leading to high-Good particle levels. Wednesday, an upper-level low pressure system will aid atmospheric mixing across northern California. In addition, light to moderate onshore winds will disperse pollutants and transport clean air into the Sacramento Valley. As a result, particle levels will be Good. Thursday, a weak ridge of high pressure aloft will decrease atmospheric mixing across northern California. However, moderate onshore winds will continue to aid dispersion, and pollutant carryover will be low. Therefore, particle levels will continue to be Good.
