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, as an upper-level low-pressure system moves across northern California, low-level mixing will increase. In addition, moderate onshore surface winds will aid pollutant dispersion. As a result, particle levels will be Good to low-Moderate. Monday and Tuesday, surface high pressure off the northern California coast will produce calm to light onshore winds. These winds will limit dispersion and allow pollutants to gradually accumulate. Therefore, particle levels will be high-Good to mid-Moderate Monday, followed by low- to mid-Moderate particle levels Tuesday.
