Monitoring the environment

EPA AirWatch


EPA AirWatch has recently been upgraded. To ensure you are viewing the most recent version of the map, we recommend you refresh the page.

EPA AirWatch is a map that shows air quality information measured by EPA’s air monitoring stations around Victoria. To get the most from EPA AirWatch, we recommend you first visit About EPA AirWatch.

Air monitoring information is also available at the hourly air quality data table.

On occasion, data may not show on the map below for a variety of reasons, such as monitoring station maintenance, equipment breakdown or website issues. See current notices below.

During winter months, EPA switches off equipment that we use to monitor summer ozone in parts of our network (mostly in metropolitan Melbourne). We will switch them back on before the start of next summer.

To give EPA’s network more coverage, we have removed ozone and visibility equipment from the Box Hill and Brighton monitoring stations for use in other areas; however both stations will continue to monitor small particles known as PM2.5, a key indicator of air quality.
