Kandukūr, nestled in the Rayalaseema region of Andhra Pradesh, India, occupies a geographically significant position within a landscape characterized by undulating terrain and a gradual transition from semi-arid plains to the Deccan Plateau. Located at approximately 15.2167° N, 79.9042° E, the city sits at an elevation of roughly 330 meters (1083 feet) above sea level, influencing local weather patterns and air circulation. The surrounding landscape is predominantly agricultural, with extensive fields of groundnut, cotton, and pulses defining the rural character. To the east, the landscape gently rises, hinting at the broader plateau, while to the west, it slopes towards the Pennar River basin, though Kandukūr itself lacks direct proximity to a major river. This agricultural intensity contributes to seasonal particulate matter, particularly during harvest periods. The urban–rural gradient is relatively sharp; Kandukūr, while a growing town, maintains a distinct separation from the surrounding agricultural lands. The region's climate is hot and dry, with limited rainfall, which can exacerbate air quality issues by reducing atmospheric cleansing through precipitation. While not directly adjacent to major industrial belts, Kandukūr’s proximity to larger urban centers like Kurnool and Kadapa means it can be affected by pollutants transported via prevailing winds. The topography, with its gentle slopes, can sometimes trap pollutants, especially during periods of low wind speed, creating localized air quality challenges. The overall geographic setting presents a complex interplay of agricultural practices, regional climate, and connectivity to larger urban areas, all impacting the city's air quality profile.

Kandukūr’s air quality experiences a distinct seasonal cycle dictated by the region’s tropical climate and agricultural practices. The dry season, spanning roughly from March to May, typically witnesses the poorest air quality. High temperatures and minimal rainfall create stable atmospheric conditions, often leading to temperature inversions where cooler air becomes trapped near the ground, preventing the dispersion of pollutants. Agricultural burning, a common practice for clearing fields after harvest, significantly contributes to particulate matter during this period. The monsoon season, from June to September, brings a welcome respite, with increased rainfall effectively washing away pollutants and improving air quality. However, the onset of the monsoon can initially be accompanied by increased humidity and fog, which can temporarily trap pollutants. October and November mark a transitional period, with decreasing rainfall and gradually increasing temperatures. December and January represent the cooler months, with relatively better air quality compared to the dry season, although occasional fog events can still lead to localized pollution spikes. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, limiting outdoor activities during peak pollution hours, typically in the morning and late afternoon. Maintaining indoor air quality through ventilation and air purifiers is also advisable. The agricultural cycle is a key driver; periods of intense planting or harvesting necessitate awareness and potentially reduced outdoor exposure.
