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
Wednesday, moderate onshore winds will aid pollutant dispersion. In addition, slightly cooler temperatures will reduce ozone production, and carryover from the previous day will be low. Thus, ozone levels will be high-Good. Thursday, onshore winds will weaken, reducing dispersion. Furthermore, sunny skies and highs in the low-90s will promote ozone development. As a result, ozone levels will be low-Moderate. Friday, light onshore winds will persist, hindering dispersion. Additionally, ample sunshine and temperatures in the mid-90s will increase ozone formation. These conditions will yield mid-Moderate ozone levels.
