Guwāhāti's air quality reflects the Brahmaputra River valley's flat alluvial plain at 55 metres surrounded by the Assam Hills and the Meghalaya Plateau, with vehicle traffic on surrounding roads and the oil refinery, tea, and construction corridor contributing local sources. The monsoon provides effective wet season cleansing, while the dry winter northeast monsoon and biomass burning from surrounding northeastern Indian forests generate seasonal PM2.5 elevation and the valley's topographic enclosure creates concentration under calm winter conditions throughout the year.
