Banjarmasin's air quality reflects the flat South Kalimantan Martapura River delta position at sea level, with vehicle density and the coal trading, manufacturing, and port corridor generating elevated PM2.5. The Java Sea provides limited maritime ventilation, while transboundary haze from Kalimantan peatland fires represents the most severe seasonal concern and Banjarmasin generally maintains moderate to elevated Indonesian Borneo coal trading capital readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Banjarmasin right now?
On 20 September 2026, overall air quality in Banjarmasin is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 6:00 AM (PM1: 100/100).
Will air quality be worse tomorrow in Banjarmasin?
On 21 September 2026, air quality conditions in Banjarmasin will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 7:00 AM (PM1: 100/100).
When is air pollution at its worst in Banjarmasin?
The biggest local contributors to pollution in Banjarmasin are traffic on the surrounding roads, light manufacturing, and fishing fleet activity, particularly once onshore breezes fall calm. Sea breezes typically keep conditions in check, except during still weather. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Banjarmasin 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.
