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, calm to light westerly winds throughout much of the day will reduce dispersion, allow pollutants to accumulate in the Sacramento region. Additionally, continued sunshine and highs in the mid- to upper-80s will promote ozone formation, resulting in mid-Moderate ozone levels. Saturday, a passing weak cold front will enhance vertical mixing and produce light to moderate onshore winds, dispersing pollutants and transporting cleaner air into the Sacramento region. Furthermore, slightly cooler temperatures and scattered clouds will inhibit ozone development, yielding Good ozone levels. Sunday, sunny skies will enhance ozone production throughout the Sacramento Valley. However, moderate and gusty north-northwesterly winds will keep pollutants well dispersed, leading to Good ozone levels.
