Air Quality Forecast

Thursday, May 13th – The next couple of days will be mostly sunny with light winds and warming temperatures. Above-average temperatures and poor night-time ventilation may allow fine particulate (PM-2.5) and ozone levels to gradually increase, but daytime ventilation should be enough to keep air quality in the AQI-Good range most of the time on Thursday and Friday. /MCKAY

About the Air Quality Index (AQI)

The AQI is an index for reporting air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

An AQI value of 100 generally corresponds to the national air quality standard for the pollutant, which is the level EPA has set to protect public health. To make it easier to understand, the AQI is divided into six categories:

Preview Only: Edit these values wihtin the WP Admin > AQI Monitoring & Burn Status
  • GoodAir quality is considered satisfactory, and air pollution poses little or no risk.Numeric Value: 0-50

  • ModerateAir 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.Numeric Value: 51-100

  • Unhealthy for SomeMembers of sensitive groups may experience health effects. The general public is not likely to be affected.Numeric Value: 101-150

  • UnhealthyEveryone may begin to experience health effects; members of sensitive groups may experience more serious health effects.Numeric Value: 151-200

  • Very UnhealthyHealth alert: everyone may experience more serious health effects.Numeric Value: 201-300

  • HazardousHealth warnings of emergency conditions. The entire population is more likely to be affected.Numeric Value: 301+

The Current Air Quality reflects the predominant air pollutant (either PM2.5, PM10, or Ozone*) with the highest reading in the monitoring network. *Ozone is only measured during ozone season, May-September.

Note: Values above 500 are considered Beyond the AQI. Follow recommendations for the “Hazardous category.” Additional information on reducing exposure to extremely high levels of particle pollution is available.
