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 and Tuesday, an upper-level ridge of high pressure will limit atmospheric mixing over the Sacramento region each day. Furthermore, periods of light and variable winds will allow pollutants to accumulate and carry over from day to day. Additionally, strong temperature inversions during the morning and evening hours will confine pollutants to the lower levels of the atmosphere. As a result, particle levels will be low-Moderate on Monday and mid-Moderate on Tuesday. Wednesday, as a trough of low pressure deepens offshore, increasing southerly winds will aid low-level mixing and dispersion in the Sacramento region. In addition, increasing clouds will hinder development of a temperature inversion during the evening. Therefore, particle levels will improve to low-Moderate.
