Cremorne sits on Sydney's Lower North Shore, its harbourside position giving it good natural ventilation similar to neighbouring Neutral Bay and Mosman, though Military Road's traffic still passes through parts of the suburb. Ferries service much of the harbour frontage. There is no industry present. Bushfire smoke is a periodic summer risk from northern hinterland bushland. Overall, background air quality here is generally very good, reflecting a leafy, low-density harbourside suburb with moderate arterial traffic on its fringe.

Frequently Asked Questions
Is air quality bad in Cremorne right now?
On 4 August 2026, overall air quality in Cremorne is fair. AQI is the main air quality indicator at 20.0/100. Pollution peaks around 7:00 PM (NO2: 20.0/100).

When is air pollution at its worst in Cremorne?
Cremorne, on the lower north shore, typically sees good air quality most of the year, with summer bushfire smoke, December to March, the main seasonal concern during hot, still conditions, and a milder rise in wood-heater smoke possible on cold winter nights. Harbourside breezes generally help clear haze quickly here.
Are air quality levels in Cremorne 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.
