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
Sunday, an approaching upper-level trough of low pressure will increase atmospheric mixing. At the surface, moderate and gusty onshore winds will disperse pollutants and carry cooler air into the Sacramento region. Therefore, despite mostly sunny skies aiding ozone development, ozone levels will be high-Good. Monday and Tuesday, mixing will continue to be enhanced as the upper-level trough traverses northern California. Furthermore, onshore surface winds will persist, transporting clean, cool air into the Sacramento region. As a result, ozone levels will be Good on both days.
