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
Wednesday, a deepening trough of low pressure will enhance atmospheric mixing across northern California. Furthermore, light to moderate north-northwesterly winds will disperse pollutants and transport cleaner air into the Sacramento Valley during the afternoon and evening. Therefore, particle levels will be Good. Thursday and Friday, moderate and gusty north-northwesterly winds will aid dispersion and low-level mixing in the Sacramento region as a surface ridge of high pressure develops over the Pacific Northwest. These conditions will result in continued Good particle levels on both days.
