Squeezed between the CBD and the historic steelworks precinct to the north, Wollongong Harbour is a small boat harbour where industrial character and city bustle sit close together. The Illawarra escarpment rising sharply behind the city can trap air against the coast on still, windless days, allowing emissions from both traffic and nearby industry to linger longer than they would in a more open setting. Sea breezes off the Tasman usually help clear things out, but this pocket of the harbour is more exposed to industrial influence than beaches further south.

When is air pollution at its worst in Wollongong Harbour?
For visitors and locals in Wollongong Harbour, the Wollongong-wide risk period is the December-to-March bushfire season, when smoke from nearby fires drifts through on hot northerlies. Winter adds its own trouble, with wood-heater smoke lingering on calm, cold nights. The rest of the year is otherwise good, so it's these months that call for caution.
Are air quality levels in Wollongong Harbour 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
