In Larrimah, occasional vehicle traffic and open farmland nearby mean particulate matter here comes more from dust and seasonal field work than congestion. With green space limited nearby, little natural filtering happens before particulates settle here. Wind patterns on any given day can shift this picture meaningfully in either direction.

Frequently Asked Questions
Is air quality bad in Larrimah right now?
On 20 September 2026, overall air quality in Larrimah is poor. AQI is the main air quality indicator at 75.1/100. Pollution peaks around 8:30 PM (PM2.5: 75.1/100).
Will air quality be worse tomorrow in Larrimah?
On 21 September 2026, air quality conditions in Larrimah will be similar to today, with AQI forecast at poor at 76.1/100. Pollution peaks around 9:30 PM (PM2.5: 76.1/100).
When is air pollution at its worst in Larrimah?
Winter is usually when particulate matter climbs highest locally, driven by heating season smoke that lingers under stagnant, cold winter air. Warmer months bring a different problem: smoke haze from nearby bushfires, as warm, dry conditions drive both ozone formation and periodic bushfire smoke from the surrounding region. Between the winter and summer extremes, spring and autumn usually bring the year's most consistently clear air.
Are air quality levels in Larrimah 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.
