Kota Kinabalu's air quality benefits from its exceptional South China Sea and Sulawesi Sea coastal position in Malaysian Sabah, with consistent South China Sea and southwest monsoon maritime breezes providing reliable tropical ventilation. Vehicle traffic on surrounding roads and the tourism, fishing, and government corridor contribute modest local sources, while transboundary haze from Indonesian Kalimantan peatland fires represents the primary severe seasonal concern and Kota Kinabalu generally maintains moderate to good Malaysian Sabah coastal readings throughout non-haze periods.

Rainfall through the monsoon usually keeps levels in check. Onshore breezes usually help clear the air, but pollution can build up when winds are light.

Are air quality levels in Kota Kinabalu 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.
