Air quality in Karratha is influenced strongly by its role as a major Pilbara iron ore and gas industry hub, with port operations, rail haulage and processing contributing dust to the local airshed alongside naturally occurring wind-blown red dust from the surrounding arid landscape. Humidity is generally low outside the wet season, and cyclone season (November-April) can bring heavy rain that temporarily clears dust but also raises the risk of storm-related disruption. Background air quality away from industrial activity is typically good.

When is air pollution at its worst in Karratha?
The most challenging air days in Karratha usually coincide with strong winds combined with dry conditions, which stir up dust from both natural desert surfaces and industrial stockpiles and haul roads around the port. This is most common outside the cyclone season, particularly in the drier, windier months. Residents should expect episodic dust haze rather than constant poor air, with conditions typically improving once winds settle or rain moves through.
Are air quality levels in Karratha based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
