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
Monday and Tuesday, an upper-level ridge of high pressure will persist over northern California, limiting atmospheric mixing. In addition, strong overnight temperature inversions will confine pollutants near the surface, while light and variable winds hinder dispersion each day. However, warm temperatures each afternoon will enhance mixing, and pollutant carryover from day to day will be low. As a result, particle levels will be low-Moderate on both days. Wednesday, increasing onshore winds ahead of an approaching cold front will effectively disperse pollutants and bring cleaner air into the Sacramento region, lowering particle levels to Good.
