Nestled in the southern Indian state of Karnataka, Mysuru occupies a strategic position at the foothills of the Chamundi Hills, with an elevation of approximately 770 meters above sea level that provides some natural ventilation but also traps pollutants under specific conditions. The city lies on the Deccan Plateau, characterized by gently undulating terrain that slopes eastward toward the Kaveri River basin, creating a subtle urban-rural gradient where agricultural lands and peri-urban settlements blend with the expanding metropolitan core. Mysuru's location between the Western Ghats to the west and the Eastern Ghats to the east influences local wind patterns, with breezes often channeling through the valley but sometimes stagnating during dry periods. The city is approximately 150 kilometers southwest of Bengaluru, placing it within Karnataka's emerging industrial corridor, particularly with the Hebbal industrial area contributing to regional emissions. Proximity to water bodies like the Kukkarahalli Lake and the Kaveri River offers limited moderating effects on air quality, though these are often overshadowed by urban sprawl and traffic congestion. The surrounding landscape includes scrub forests and agricultural zones, where seasonal crop residue burning can exacerbate particulate matter levels, while the city's growth as a tourism and education hub intensifies local pollution sources like vehicle exhaust and construction dust, creating a complex interplay between geography and anthropogenic factors that shape its air quality challenges.

Mysuru's air quality follows a distinct seasonal rhythm driven by its tropical wet-and-dry climate, with pollution peaking sharply from December through March due to a combination of meteorological stagnation and human activities. During these winter and early spring months, cooler temperatures and frequent temperature inversions trap pollutants close to the ground, while low wind speeds and morning fog exacerbate the accumulation of vehicle exhaust, road dust, and industrial emissions from the Hebbal area. Sensitive groups, such as those with respiratory conditions, should limit outdoor exertion in these months, especially during early mornings when pollution concentrations are highest. The southwest monsoon from June to September brings relief, as heavy rainfall scrubs the atmosphere of particulate matter, though occasional thunderstorms can stir up dust temporarily. This period offers the best conditions for outdoor activities, with clearer skies and improved air quality. The post-monsoon months of October and November see a gradual deterioration as dry conditions return, setting the stage for the peak pollution season. Throughout the year, localized factors like waste burning and construction dust add to the baseline pollution, making year-round vigilance advisable for vulnerable populations, who should monitor air quality reports and plan activities for midday when dispersion is better.
