Port Augusta's air quality has improved with the 2016 closure of the coal-fired power stations that once operated nearby, and background conditions are now generally good, aided by consistent Spencer Gulf sea breezes. The main remaining challenges are dust storms, which are a well-known feature of this gateway-to-the-outback location, along with low humidity and a wide daily temperature range typical of semi-arid Australia. There is limited heavy industry in the town today.

When is air pollution at its worst in Port Augusta?

The most notable air quality drops in Port Augusta come with dust storm conditions, when strong, dry winds sweep across the surrounding plains and Spencer Gulf shoreline, most likely during hot, windy stretches in spring and summer. Expect these to be sudden, visible events rather than persistent haze, easing quickly once the wind changes. Outside of dust events, the sea breeze off the gulf generally keeps the air clear.

Are air quality levels in Port Augusta 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.
