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, light north-northwesterly winds will limit pollutant dispersion in the Sacramento region. In addition, an evening temperature inversion will trap pollutants at the surface. Therefore, particle levels will be low- to mid-Moderate. Monday, a weak cold front will impact northern California, enhancing atmospheric mixing. However, light onshore winds will continue to hinder dispersion, while another evening temperature inversion will confine pollutants near the ground. These conditions will keep particle levels low- to mid-Moderate. Tuesday, an upper-level trough of low pressure passing over the region will aid vertical mixing. At the surface, moderate to gusty onshore winds and rain showers will disperse pollutants. Thus, particle levels will improve to high-Good to low-Moderate.
