Nestled in the Nashik district of Maharashtra's northern region, Malegaon occupies a strategic position on the banks of the Girna River, approximately 280 kilometers northeast of Mumbai. Situated at an elevation of around 438 meters above sea level, the city lies within the broader Deccan Plateau, characterized by relatively flat terrain interspersed with low hills that minimally disrupt atmospheric circulation. This urban center functions as a crucial textile manufacturing hub, surrounded by agricultural zones where sugarcane, cotton, and grapes dominate the landscape, creating a distinct urban–rural gradient. Malegaon's location in India's industrial belt, particularly its proximity to major transportation corridors like National Highway 3, exacerbates air quality challenges. The city's geography—sandwiched between the Satpura Range to the north and the Western Ghats to the west—creates a semi-enclosed basin effect that traps pollutants, especially during cooler months. While the Girna River provides some local moisture, it is insufficient to significantly cleanse the air, and the absence of large water bodies nearby limits natural dispersion mechanisms. The dense concentration of power looms in compact urban areas, combined with vehicular emissions from growing traffic, results in high particulate matter levels that linger due to the region's topography and limited wind patterns.

Malegaon's air quality follows a distinct seasonal rhythm shaped by its tropical wet-and-dry climate. During the winter months from November to February, pollution peaks dramatically as cooler temperatures and frequent temperature inversions trap pollutants close to the ground, compounded by calm winds and dense fog that reduce dispersion. This period poses severe risks for outdoor activities, especially for sensitive groups like children, the elderly, and those with respiratory conditions, who should limit exposure and use protective masks. The summer season from March to May brings extreme heat that increases ozone formation and resuspends road dust, though occasional pre-monsoon winds provide some relief by dispersing pollutants. The monsoon from June to September offers the cleanest air, as heavy rainfall from the southwest monsoon washes away particulate matter and suppresses dust sources, making this the optimal time for outdoor pursuits. Post-monsoon months from October onward see a rapid deterioration in air quality as agricultural residue burning in surrounding fields combines with returning industrial emissions and festive fireworks, creating a hazardous mix. Residents should monitor local air quality advisories year-round, with particular vigilance during the high-pollution winter window when indoor air purifiers and reduced outdoor exertion become essential.
