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 ridge of high pressure aloft will limit atmospheric mixing. In addition, calm to light southerly winds will hinder dispersion and allow pollutants to accumulate in the Sacramento region. Therefore, particle levels will be low-Moderate. Monday, a temperature inversion will confine pollutants near the surface early in the day. However, light northwesterly winds will aid dispersion during the afternoon and evening, allowing particle levels to remain low-Moderate. Tuesday, increasing northwesterly winds will disperse pollutants in the Sacramento region as a surface ridge of high pressure strengthens over the Pacific Northwest. Therefore, particle levels will improve to high-Good.
