Coal has long defined Collie, and the town's power stations and mining operations add a distinctive industrial layer to what would otherwise be a typically clean southwest air profile. Dust from mining activity and occasional emissions from power generation are the standout local concerns, layered on top of the region's usual Mediterranean pattern of dry summers and low humidity. Bushfire smoke is also a risk each year between December and March, given the extensive jarrah forest surrounding the town. Away from these industrial and seasonal fire influences, Collie benefits from reasonably good ventilation and generally moderate air quality.
