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, a temperature inversion will confine pollutants near the surface early in the day, while light winds hinder dispersion. However, increasing onshore winds will aid dispersion during the afternoon, allowing particle levels to remain mid-Moderate. Monday, as a surface ridge of high pressure develops over the Pacific Northwest, moderate northwesterly winds will aid dispersion in the Sacramento region throughout the day. Therefore, particle levels will improve to low-Moderate. Tuesday, light winds will allow pollutants to accumulate early in the day. However, as a trough of low pressure aloft moves inland over northern California, atmospheric mixing will improve. In addition, increasing southerly winds will aid dispersion during the evening. As a result, particle levels will remain low-Moderate.
