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, upper-level high pressure passing over northern California will inhibit atmospheric mixing, while calm to light surface winds will reduce dispersion. Furthermore, temperature inversions through the morning and evening hours will confine pollutants to the lower levels of the atmosphere. As a result, particle levels will be low-Moderate. Sunday and Monday, as a low pressure system deepens off the California Coast, atmospheric mixing will increase over the Sacramento region. Additionally, strengthening southerly to southwesterly winds will promote dispersion. Therefore, particle levels will be Good on both days.
