Air quality in Hobart is generally good overall, helped by the city's exposure to Roaring Forties westerlies and its position on the Derwent estuary. The main local concern is wood heater smoke in winter, which can settle in low-lying suburbs on still, cold nights, particularly where the surrounding hills limit air movement and trap cooler air near the ground. Bushfire smoke from further afield across southern Tasmania can also occasionally reach the city during severe fire seasons.

Frequently Asked Questions
Is air quality bad in Hobart right now?
On 4 August 2026, overall air quality in Hobart is fair. AQI is the main air quality indicator at 38.3/100. Pollution peaks around 8:00 PM (NO2: 38.3/100).
Will air quality be worse tomorrow in Hobart?

When is air pollution at its worst in Hobart?
Winter evenings are the time most likely to bring noticeably reduced air quality in Hobart, as wood heater smoke accumulates in low-lying parts of the city under still conditions before dispersing the next day. Outside winter, Hobart's air is typically among the cleanest of any Australian capital, thanks to its southerly, wind-exposed position.
Are air quality levels in Hobart 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.
