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
Saturday and Sunday, a temperature inversion will confine pollutants near the surface each morning. Furthermore, light winds throughout the period will lead to pollutant build-up in the Sacramento region, resulting in low- to mid-Moderate particle levels on both days. Monday, a weak cold front will impact northern California, enhancing atmospheric mixing and producing light to moderate onshore winds in the afternoon. These conditions will disperse pollutants, leading to high-Good to low-Moderate particle levels.
