Tindivanam occupies a strategic position in Tamil Nadu's Viluppuram district, situated approximately 120 kilometres southwest of Chennai along the bustling Chennai–Trichy National Highway 45. This town of 60,000 residents lies within the broader Coromandel coastal plain, characterized by flat to gently undulating terrain with an average elevation of just 50 metres above sea level. Tindivanam's geography places it at the transitional zone between the Bay of Bengal's coastal influence and the interior agricultural heartlands, creating a distinctive urban-rural gradient where commercial activities blend with surrounding farmlands. The town's location within the Palar River basin—though the riverbed often runs dry—contributes to significant road dust issues, particularly during drought periods. Proximity to major transportation corridors ensures constant vehicular emissions, while its position in Tamil Nadu's intensive agricultural belt means seasonal agricultural burning significantly impacts air quality. The flat topography and low elevation inhibit natural ventilation, allowing pollutants to accumulate rather than disperse. Tindivanam's urban character as a regional commercial hub for agricultural produce means commercial activities and construction projects add to the pollution burden, while the absence of significant water bodies nearby reduces natural cleansing effects that coastal cities might experience.

Tindivanam's tropical wet-and-dry climate creates distinct seasonal patterns in air quality that residents must navigate carefully. During the northeast monsoon season from October to December, increased humidity and occasional cyclonic systems from the Bay of Bengal can trap pollutants near the surface, particularly when combined with agricultural burning during the post-harvest period. The peak pollution months from November through February coincide with cooler temperatures that frequently create temperature inversions, trapping vehicular emissions, road dust, and smoke from agricultural burning in a stagnant layer close to the ground. Morning fog during these months further exacerbates pollution accumulation. The summer months from March to May bring extreme heat that accelerates photochemical reactions, though stronger daytime winds provide some dispersal of pollutants. The southwest monsoon from June to September offers the cleanest air, as heavy rains effectively wash pollutants from the atmosphere and winds disperse remaining contaminants. Sensitive groups including children, elderly residents, and those with respiratory conditions should minimize outdoor activities during morning hours in peak pollution months, particularly when agricultural burning is prevalent. The post-monsoon period from October onward requires heightened awareness as pollution begins to build toward its annual maximum.
