Merewether sits directly on the Newcastle coastline, its famous beach and ocean baths exposed to strong onshore breezes that provide excellent natural ventilation and keep background air quality among the best in the city. Traffic is light, confined to local streets rather than major through-routes. There is no industry nearby, in contrast to Newcastle's port precinct further north. Bushfire smoke is a periodic summer risk from hinterland bushland. Overall, this beachside suburb enjoys consistently clean, well-mixed coastal air.

When is air pollution at its worst in Merewether?
Merewether's beachside position generally keeps air quality good, with the main concerns being summer bushfire smoke, December to March, on hot, still days, and occasional wood-heater smoke on cold, calm winter nights. Being right on the coast, onshore breezes here tend to clear haze faster than in suburbs further inland.
Are air quality levels in Merewether 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.
