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.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: 6/28/2017 - Advisory for smoke impacts from the Hill Fire, near Park Hill Rd, east of Santa Margarita: If smoke or ash is visible in the air, County officials recommend that all adults and children avoid strenuous outdoor activity, remain indoors as much as possible, and set any heating/air conditioning/ventilation systems to recirculation. The public is advised to take action and consult your doctor if you are experiencing health problems. If staying indoors does not provide relief, temporarily leaving the area and going to a location where the air is not visibly affected by the fire is advised ------ 7/4/2017 - Fireworks Celebrations Can Influence Local Air Quality: The San Luis Obispo County Air Pollution Control District encourages everyone to have an enjoyable and safe July 4 holiday. Simultaneously, the Air District officials want to remind Central Coast residents that fireworks increase levels of dangerous particulate matter and pose a health threat. July 4 fireworks can temporarily increase air pollution in local areas. The APCD advises individuals that will be near neighborhood fireworks and large fireworks displays to take appropriate cautionary measures as individual health conditions dictate. Fireworks release large qualities of particulate matter, such as soot, ash, and metals. During prime time for fireworks displays (i.e., 8-10 p.m.) significant increases in levels of particulate pollution are possible, especially in areas with substantial fireworks activity and stagnant weather conditions. Although these levels may dissipate by midnight, elevated pollution concentrations can last until morning if wind conditions are stagnant. Particle pollution can cause serious health impacts, especially to people with heart or lung disease, elderly individuals, and small children. Residents should use common sense and take precautions to reduce the harmful health effects associated with increased air pollution from fireworks. These precautions are especially important for people with existing respiratory or heart conditions. If you are impacted by local air quality conditions, remain indoors as much as possible, and set the air conditioning/ventilation systems to recirculation. Consult your medical professional if you are experiencing health problems.
