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
Sunday and Monday, atmospheric mixing will improve as a deep trough of low pressure moves across northern California. In addition, periods of moderate southerly to southwesterly winds will disperse pollutants and bring clean air into the Sacramento region. Furthermore, much cooler temperatures and scattered rain showers on Monday will reduce ozone formation. Therefore, ozone levels will be Good on both days. Tuesday, as the low pressure system departs eastward, increasing sunshine will aid ozone formation, and lighter onshore winds will limit pollutant dispersion. However, low pollutant carryover from previous days will keep ozone levels high-Good.
