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, an upper-level low pressure system just off the northern California coast will aid atmospheric mixing. In addition, persistent onshore winds will continue to transport cleaner air into the Sacramento region. However, increasing sun and high temperatures in the mid-90s will support ozone development. As a result, ozone levels will be mid-Moderate. Tuesday, slightly cooler temperatures will reduce ozone formation as increasing onshore winds promote low-level mixing and dispersion. Therefore, ozone levels will improve to low-Moderate. Wednesday, westerly to southwesterly winds will weaken through the Sacramento region, limiting pollutant dispersion. Furthermore, mostly sunny skies and temperatures in the mid-90s will enhance ozone formation. As a result, ozone levels will be mid-Moderate.
