AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Thursday, light to moderate onshore winds will aid pollutant dispersion in the Sacramento region. However, sunny skies and temperatures in the upper-90s will support ozone formation. In addition, smoke from the Detwiler fire in Mariposa County will be transported into the foothills east of Sacramento, enhancing ozone formation and increasing particle levels. Therefore, ozone levels will be Unhealthy for Sensitive Groups. Friday is a Spare The Air day in the Sacramento region. Warmer temperatures will enhance ozone formation, and lighter winds will inhibit pollutant dispersion. Furthermore, smoke impacts from the Detwiler fire will continue to enhance pollutant levels, especially in the foothills. These conditions, combined with high pollutant carryover from Thursday, will lead to Unhealthy for Sensitive Groups ozone levels. Saturday, an upper-level ridge of high pressure will build over northern California, reducing vertical mixing in the atmosphere. In addition, temperatures over 100F will enhance ozone formation, and smoke from the Detwiler fire will continue to impact the region. Therefore, despite moderate winds in the afternoon aiding dispersion at the surface, ozone levels will remain Unhealthy for Sensitive Groups.
