Due to technical difficulties, air quality data is not currently uploading to our website. ACT Health continues to monitor air quality and will still issue public health warnings if required.
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 for ozone and nitrogen dioxide, over 8 hours for carbon monoxide, 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.

Please note all data shown on this site is in Australian Eastern Standard Time (AEST) and is not adjusted for Daylight Saving Time (DST).
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.
How to use the graphs
To use these graphs, hover your mouse over the graph lines to see the Air Quality Index (AQI) values for each station. Click on the Date and Time function in the table to select other periods. Click on the Name function to select/deselect stations. The legend for the graphs can be opened from the bottom right corner.
Please note all available data may be subject to further modification and validation. Gaps in the data mean a pollutant wasn’t measured at that site, an instrument was briefly offline or not enough data was collected during the time period.
Note: This graph shows the AQI for PM2.5 as a 24 hour rolling average.
