Air quality in Greystanes (2145)

Air quality in Greystanes (2145) is measured using the NSW Environment Protection Authority's (EPA) network of monitoring stations and expressed as an Air Quality Index (AQI). The AQI combines readings for particulate matter (PM2.5 and PM10), ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide into a single score. The data shown covers the monitoring region closest to Greystanes in the Cumberland LGA and includes an annual summary of days exceeding safe thresholds.

Sydney's air quality exceeds national standards on relatively few days per year compared to other major cities, but the distribution is uneven. Suburbs near major motorways, industrial precincts, or airports tend to see more exceedances. If Greystanes shows elevated PM2.5 readings, check whether the monitoring station is representative of residential streets or positioned near a pollution source. EPA station placement affects the numbers.
