Kiama enjoys generally excellent air quality thanks to its exposed coastal position on the NSW South Coast, with onshore winds off the Tasman Sea providing near-constant ventilation. Dairy farming surrounds the town rather than heavy industry, so agricultural odours are more common than particulate pollution. Wood heater smoke can build on still winter nights, and summer bushfire smoke occasionally drifts down from the escarpment. Traffic along the Princes Highway corridor is the main localised source of vehicle emissions.

Frequently Asked Questions
Is air quality bad in Kiama right now?
On 17 September 2026, overall air quality in Kiama is good. AQI is the main air quality indicator at 16.7/100. Pollution peaks around 10:00 PM (PM2.5: 16.7/100).
Will air quality be worse tomorrow in Kiama?
On 18 September 2026, air quality conditions in Kiama will be worse than today, with AQI forecast at fair at 31.4/100. Pollution peaks around 6:00 PM (PM2.5: 31.4/100).
When is air pollution at its worst in Kiama?
Kiama's coastal position keeps air quality good most of the year, with the main risk arriving during summer bushfire season (December–March) when fire smoke from the surrounding escarpment and inland ranges can blow through on northerly winds. Winter evenings in cooler months occasionally bring mild wood-smoke haze in sheltered pockets, but prolonged poor-air stretches are uncommon here.
Are air quality levels in Kiama 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.
