Air quality in Cowan (2081)
Cowan (2081) falls within the Hornsby local government area. Air quality here is influenced by traffic density on nearby arterials, prevailing wind patterns, and proximity to industrial land uses.

Wood-fire heaters are a surprisingly large contributor to winter air pollution in Sydney's middle and outer rings. If Cowan is a cooler area where wood fires are common, winter PM2.5 readings can spike significantly above summer averages.
