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
Friday, increasing sunshine will aid ozone production in the Sacramento region. However, light to moderate north-northwesterly winds will disperse pollutants. In addition, cool temperatures and low pollutant carryover from Thursday will keep ozone production in check. As a result, ozone levels will continue to be Good. Saturday and Sunday, mostly sunny skies will aid ozone development, while calm to light winds will allow pollutants to accumulate in the Sacramento region. However, mild temperatures will continue to limit ozone production, keeping ozone levels Good to high-Good on both days.
