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
Friday, westerly to northwesterly winds will disperse pollutants and transport clean air into the Sacramento region. These conditions, combined with low pollutant carryover from Thursday, will yield high-Good particle levels. Saturday, a ridge of high pressure aloft will reduce atmospheric mixing over the Sacramento Valley. In addition, a temperature inversion during the morning and evening hours will confine pollutants near the surface, and calm to light and variable winds will limit dispersion. Therefore, particle levels will increase to low-Moderate. Sunday, mixing will improve slightly as a cold front passes over northern California. However, calm to light southerly to southeasterly winds will hinder dispersion, while increasing humidity will promote particle formation. Additionally, a morning temperature inversion will trap pollutants at ground-level. Thus, particle levels will be mid-Moderate.
