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.

As a result, particle levels will be low-Moderate on both days. Friday, moderate to occasionally heavy rain will overspread the Sacramento region, enhancing atmospheric mixing ahead of an approaching cold front. In addition, moderate southeasterly winds will continue to aid dispersion. Therefore, particle levels will improve to high-Good.
