Randwick sits on an elevated ridge in Sydney's eastern suburbs, close to the coast, a position that supports reasonable natural ventilation despite fairly steady traffic generated by the nearby university, hospital precinct, and racecourse. Ocean breezes reach the suburb readily given its proximity to the coast. There is no heavy industry here. Bushfire smoke is a periodic summer risk from more distant hinterland. Overall, background air quality is good, with traffic around key institutions the main localised factor.

Frequently Asked Questions

Is air quality bad in Randwick right now?

On 4 August 2026, overall air quality in Randwick is fair. AQI is the main air quality indicator at 28.6/100. Pollution peaks around 7:00 PM (NO2: 28.6/100).

Will air quality be worse tomorrow in Randwick?

On 5 August 2026, air quality conditions in Randwick will be similar to today, with AQI forecast at fair at 28.4/100. Pollution peaks around 11:00 PM (NO2: 28.4/100).

When is air pollution at its worst in Randwick?

Randwick's eastern-suburbs position benefits from onshore breezes most of the year, so summer bushfire smoke (December–March) arriving on northwesterly winds is the main seasonal concern. Expect generally clean coastal air otherwise, with any smoke haze typically clearing quickly once sea breezes re-establish each afternoon.

Are air quality levels in Randwick 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.
