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 and Wednesday, as an upper-level low pressure system moves across northern California, atmospheric mixing will be enhanced. Additionally, clouds, rain showers, and cool temperatures will inhibit ozone production. As a result, ozone levels will be Good on both days. Thursday, as the trough of low pressure departs to the east, atmospheric stability will increase over northern California, reducing vertical mixing. In addition, mostly sunny skies will aid ozone formation, and calm to light west-northwesterly winds will limit pollutant dispersion. However, cool temperatures will keep ozone production in check, leading to high-Good ozone levels.
