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
Saturday, periods of moderate south-southeasterly winds will aid dispersion during the afternoon. However, these winds will decrease during the evening hours, allowing pollutants to accumulate. Therefore, particle levels will be low-Moderate. Sunday and Monday, temperature inversions each morning will trap pollutants near the ground. In addition, an offshore cold front will generate calm to light southeasterly winds throughout much of the period. These winds will limit dispersion and allow pollutants to accumulate, keeping particle levels low-Moderate on both days.
