Current and forecast air quality

Air quality index (AQI) and concentration values are updated hourly and a daily air quality forecast is made for the Greater Sydney Metropolitan Region at 4pm each day.


               The Vineyard monitoring site has been decommissioned and there will be no data until a new site is established.

               Some web links to other sites may not work due to their planned IT maintenance including links in our email AQI
