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
Tuesday, a trough aloft will shift southward across northern California, with periods of showers and thunderstorms supporting atmospheric mixing. Furthermore, gusty onshore winds will keep pollutants well dispersed, resulting in Good particle levels. Wednesday, a weak surface ridge of high pressure will develop across far northern California, producing light northwesterly winds through the Sacramento Valley. These winds will carry clean air into the region, allowing particle levels to remain Good. Thursday, mixing will be limited as upper-level high pressure approaches from the west. In addition, a morning temperature inversion will trap pollutants near the ground, while calm to light southeasterly morning winds will allow pollutants to accumulate. However, light westerly to northwesterly afternoon winds will aid dispersion, and pollutant carryover from the previous days will be low. Thus, particle levels will be high-Good.
