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
Friday and Saturday, periods of moderate and gusty north-northwesterly winds will aid dispersion and low-level mixing in the Sacramento region as a surface ridge of high pressure gradually moves across the Pacific Northwest. These conditions will result in continued Good particle levels on both days. Sunday, as surface high pressure moves into the Great Basin, winds will become calm in the Sacramento region, leading to pollutant accumulation. In addition, morning and evening temperature inversions will trap pollutants in the lower levels of the atmosphere. However, daytime temperatures warming into the upper-70s will enhance mixing through the afternoon hours. These conditions, combined with low pollutant carryover from Saturday, will lead to low-Moderate particle levels.
