Frankston sits directly on Port Phillip Bay in Melbourne's outer south-east, its beachfront position benefiting from strong onshore bay breezes that provide good ventilation and generally clean background air. Traffic concentrates around the town centre and station rather than the foreshore itself. There is no significant industry. Bushfire smoke is a periodic summer risk from the nearby Mornington Peninsula hinterland. Overall, this bayside suburb enjoys notably better air quality than Melbourne's more inland outer suburbs.

When is air pollution at its worst in Frankston Beach?
Frankston Beach benefits from Port Phillip Bay's onshore breezes for much of the year, with summer bushfire smoke, December to March, the main exception during hot, windless spells. Winter wood-heater smoke is generally less pronounced here than in more sheltered inland suburbs.
Are air quality levels in Frankston Beach 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.
