Air Quality Report


What is AQI?

The Air Quality Health Index or "AQHI" is a scale designed to help you understand what the air quality around you means to your health.

It is a health protection tool that is designed to help you make decisions to protect your health by limiting short-term exposure to air pollution and adjusting your activity levels during increased levels of air pollution. It also provides advice on how you can improve the quality of the air you breathe.

This index pays particular attention to people who are sensitive to air pollution and provides them with advice on how to protect their health during air quality levels associated with low, moderate, high and very high health risks.

The AQHI communicates four primary things;

  • A number from 1 and 10+ indicating the quality of the air. The higher the number, the greater the health risk associated with the air quality. When the amount of air pollution is very high, the number will be reported as 10+.

  • A health risk category that describes the level of health risk associated with the index reading (e.g. Low, Moderate, High, or Very High Health Risk).

  • Health messages customized to each category for both the general population and the 'at risk' population.

  • Current hourly AQHI readings and maximum forecasted values for today, tonight and tomorrow.

Main Pollutant



Ozone is a gas comprised of three oxygen (O3) atoms. It is unstable and reacts easily to other gases. In its natural state, it is a component in several levels of the atmosphere. At high altitudes, it provides protection by absorbing large amounts of ultraviolet radiation. At ground level, however, high concentrations pose a health and environmental threat. It is also one of the principal components of smog. Ozone levels are generally higher in summer, during hot sunny weather. Concentrations are usually highest in late afternoon. Ozone is a pollutant that can travel large distances. Periods of high ozone levels can persist anywhere from a few hours to a few days, depending on weather conditions.
