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
Thursday, aloft low pressure and scattered rain showers will enhance atmospheric mixing over the Sacramento region. Furthermore, moderate to gusty westerly winds will disperse pollutants, yielding Good particle levels. Friday, as the next storm system impacts northern California, widespread rain and moderate to gusty southerly to southeasterly winds will keep pollutants well dispersed, resulting in continued Good particle levels. Saturday, a morning temperature inversion will develop, confining pollutants near the ground. Additionally, upper-level high pressure over northern California will reduce mixing, and light southwesterly afternoon winds will limit dispersion. However, low pollutant carryover from the previous days will lead to high-Good particle levels.
