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, as upper-level high pressure moves east of the region, atmospheric mixing will improve. However, calm to light northerly surface winds will reduce dispersion, allowing pollutants to accumulate in the Sacramento area. Therefore, particle levels will range from high-Good to mid-Moderate. Monday and Tuesday, morning inversions will trap pollutants at ground level. However, onshore winds will strengthen each afternoon, aiding pollutant dispersion. Thus, particle levels will range from Good to low-Moderate on both days.
