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, a strong trough of low pressure aloft will impact northern California, producing scattered showers and thunderstorms, and periods of gusty southerly winds. These conditions will enhance mixing and keep pollutants well dispersed, leading to Good particle levels. Monday, mixing will decrease slightly as the aloft trough weakens and departs to the south. Furthermore, light winds will hinder dispersion throughout the day. However, pollutant carryover will be low, keeping particle levels Good. Tuesday, a temperature inversion will hinder low-level mixing early in the day as a ridge of high pressure aloft moves across northern California. In addition, light southeasterly to southwesterly winds will limit dispersion. As a result, particle levels will range from high-Good to low-Moderate.
