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 and Saturday, strong temperature inversions will confine pollutants near the surface each morning. In addition, periods of light onshore winds will hinder dispersion in the Sacramento region. Furthermore, sunny skies and high temperatures near 100F will enhance ozone development, leading to Unhealthy for Sensitive Groups ozone levels on both days. Sunday, an approaching trough of low pressure will aid atmospheric mixing. In addition, increasing onshore winds will promote dispersion. However, sunny skies and continued hot temperatures will support ozone development, resulting in high-Moderate ozone levels.
