Bandar Seri Begawan's air quality reflects the flat Brunei Darussalam coastal position on the Brunei River at the South China Sea, with vehicle traffic on surrounding roads and the government, oil wealth, and services corridor contributing local sources. Consistent South China Sea maritime breezes provide ventilation, while transboundary haze from Indonesian and Malaysian Borneo peatland fires represents the primary severe seasonal concern and Bandar Seri Begawan generally maintains moderate to good conditions outside haze episodes throughout most of the year.
