Hourly update of air quality in Western Australia.
Last updated: 2 December 2019

The Department of Water and Environment Regulation operates an air quality monitoring network with sites in Perth and regional areas of Western Australia.

Monitoring is carried out according to the requirements of the National Environment Protection (Ambient Air Quality) Measure and improves our understanding of air quality trends, and the long term impacts on Western Australian communities.

Data from the monitoring network is presented online as ambient concentrations and air quality index (AQI) values which are updated hourly.
