Worst air pollution Byron Bay, today and tomorrow

On 5 August 2026, overall air quality in Byron Bay is fair. AQI is the main air quality indicator at 25.7/100. Pollution peaks around 4:00 PM (O3: 25.7/100).

On 6 August 2026, air quality conditions in Byron Bay will be similar to today, with AQI forecast at fair at 23.4/100. Pollution peaks around 3:00 PM (O3: 23.4/100).

Byron Bay's air stays clean for most of the year thanks to onshore breezes, but late-dry-season hinterland burns between August and November can send smoke drifting over town on still mornings, and cane-fire smoke lingers into early summer further north. Expect the occasional hazy, smoky day rather than a sustained problem — check conditions before long beach runs during that window.

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.

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.
