Air quality in the ACT

ACT Health reports on air quality using up-to-date, accurate data on levels of pollutants in the air. The Air Quality Index (AQI) displayed on this page provides a comparison of air pollutants, standardising measurements of ozone, carbon monoxide, nitrogen dioxide, and airborne particles in the environment in the ACT.

For health advice relating to air quality in the ACT, please refer to Air Quality Health advice Portal.

The Air Quality Index (AQI) readings on this page are updated with information calculated on data readings averaged over 1 hour nitrogen dioxide, over 8 hours for carbon monoxide and ozone, and over 24 hours for particulates.

The figures represented below are averages over time, as prescribed by the NEPM standards. This means that if there is a sudden onset weather or smoke event (for example a dust storm or bush fire), it is possible that people will see the visible pollutant (smoke or dust) in the air before it starts to register on these graphs.

If this happens, ACT Health will assess the air quality and publish a public health alert, if required.

If you would like to see the grass pollen count for today and the next 6 days, visit the Canberra Pollen Count and Forecast Service. You can also download the AirRater app This free app provides users with up-to-date information on total pollen (including tree and grass pollens), smoke pollution and temperature in the ACT. Please note that pollen levels may vary between AirRater and the Canberra Pollen Count and Forecast Service from time to time. These differences arise because AirRater measures total pollens and Canberra Pollen Count and Forecast Service measures grass pollen only.

Carbon monoxide and nitrogen dioxide are not measured in Civic.

Please note all available data may be subject to further modification and validation. Other gaps in the data mean a pollutant wasn’t measured at that site, an instrument was briefly offline due to maintenance work or not enough data was collected during the time period.
