As a coastal holiday town on Wallis Lake, Forster generally enjoys clean air driven by consistent onshore breezes off the Tasman Sea, which disperse local pollutants efficiently. The main risk comes in summer, when bushfire smoke from the Great Lakes hinterland or further afield can drift over the coast during dry, high fire-danger periods, as seen during the 2019-20 Black Summer fires. Traffic and wood-smoke sources are limited given the town's modest size and holiday character.

Frequently Asked Questions

Is air quality bad in Forster right now?

On 4 August 2026, overall air quality in Forster is fair. AQI is the main air quality indicator at 39.1/100. Pollution peaks around 10:00 PM (NO2: 39.1/100).

Will air quality be worse tomorrow in Forster?

On 5 August 2026, air quality conditions in Forster will be similar to today, with PM1 forecast at fair at 28.9/100. Pollution peaks around 9:00 PM (NO2: 46.3/100).

When is air pollution at its worst in Forster?

Forster's air is at its worst during summer bushfire season, when smoke from hinterland or regional fires can blanket the coast on northerly or westerly winds, sometimes lingering if sea breezes fail to clear it. Outside of fire risk periods, expect consistently clean coastal air, with only mild wood-smoke haze possible on still winter nights in town.

Are air quality levels in Forster 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.
