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, as a broad surface ridge of high pressure stretches across central California, calm to light southerly winds will limit dispersion and gradually transport regional pollutants into the Sacramento Valley. In addition, a morning temperature inversion will hinder low-level mixing, resulting in low-Moderate particle levels. Tuesday, as a cold front approaches northern California, moderate southeasterly winds will aid dispersion throughout the day. In addition, periods of light to moderate rain will promote atmospheric mixing. However, regional pollutant carryover will allow particle levels to remain low-Moderate. Wednesday, atmospheric mixing will gradually decrease as an aloft ridge of high pressure strengthens offshore. In addition, light and variable winds will reduce dispersion, leading to another day of low-Moderate particle levels.
