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)

Forecast Discussion: Today, light northerly winds will aid pollutant dispersion in Rochester. However, moisture associated with fog and mist will enhance particle formation, and regional pollutant carryover from previous days will be high. Therefore, AQI levels will be low-Moderate. Tomorrow, moderate southwesterly winds will disperse pollutants and transport cleaner air into the Rochester region, leading to Good AQI levels. Thursday and Friday, lighter southerly to southeasterly winds will bring pollutants and moisture into Rochester. These conditions will aid particle formation, leading to low-Moderate AQI levels on both days. Saturday, moderate southeasterly winds will continue to bring regional pollutants into Rochester, resulting in low-Moderate AQI levels. Sunday, light winds early in the day will reduce mixing and dispersion, allowing pollutants to build up in Rochester. However, northwesterly winds in the afternoon will disperse pollutants, keeping AQI levels low-Moderate.
