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 and Thursday, a ridge of high pressure aloft will reduce atmospheric mixing over northern California each day. In addition, light and variable winds will allow pollutants to accumulate in the Sacramento region, while morning and evening temperature inversions confine pollutants near the surface. Furthermore, areas of fog will promote particle formation early in the day on Thursday. These conditions will lead to high-Moderate particle levels on both days. Friday, as the ridge aloft shifts offshore, atmospheric mixing will improve. However, periods of calm winds and pollutant carryover from the previous day will allow particle levels to remain mid-Moderate.
