Local Environmental Conditions
This location in Canberra combines built-up streets with more open land, so local traffic matters, though emissions are less concentrated than in a city center. Lying in a valley at around 560 m, the area is prone to temperature inversions that hold pollutants near the ground when winds drop. Home heating, especially wood stoves and fireplaces, adds smoke and fine particles in the colder months.
Summers are mild, averaging around 18°C in the warmest month, so ozone usually stays moderate even from December to February. Calm, cold weather from May to August, averaging 4°C, lets the valley fill with pollution from home heating and traffic overnight. From one day to the next, still, dry weather allows pollution to accumulate, and wind or rain clears it out.

Frequently Asked Questions About Air Quality in Australian Capital Territory
Is air quality bad in Weston Creek right now?
On 7 October 2026, overall air quality in Weston Creek is fair. AQI is the main air quality indicator at 23.3/100. Pollution peaks around 1:00 AM (PM10: 23.3/100).

When is air pollution at its worst in Weston Creek?
Summers are mild, averaging around 18°C in the warmest month, so ozone usually stays moderate even from December to February. Calm, cold weather from May to August, averaging 4°C, lets the valley fill with pollution from home heating and traffic overnight. From one day to the next, still, dry weather allows pollution to accumulate, and wind or rain clears it out.
Are air quality levels in Weston Creek 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.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
