Mittagong sits at real elevation in the Southern Highlands, around 600 metres, which brings cooler nights and a strong tendency for winter temperature inversions to trap smoke from wood heaters over the town centre. This is the town's standout air quality issue, alongside occasional bushfire smoke drifting through the surrounding forested ranges in summer. There is no heavy industry nearby, and background conditions are otherwise clean, helped by the elevated, semi-rural setting away from major urban emission sources.

Frequently Asked Questions
Is air quality bad in Mittagong right now?
On 25 August 2026, overall air quality in Mittagong is moderate. AQI is the main air quality indicator at 44.8/100. Pollution peaks around 12:00 AM (NO2: 44.8/100).
Will air quality be worse tomorrow in Mittagong?
On 26 August 2026, air quality conditions in Mittagong will be better than today, with AQI forecast at fair at 39.1/100. Pollution peaks around 9:00 PM (NO2: 39.1/100).
When is air pollution at its worst in Mittagong?
Mittagong's elevation and cool climate make wood-heater smoke the main issue, building up on calm winter nights when smoke settles into the valley instead of dispersing. Summer bushfire smoke is the other seasonal risk, arriving with dry northerlies between December and March. Most days remain clear, so the practical advice is to watch forecasts around both seasonal windows.
Are air quality levels in Mittagong 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.
