Hebli, a small town nestled in the Belagavi district of Karnataka, India, occupies a geographically significant position within the Deccan Plateau. Located at approximately 15.4858° N latitude and 75.1283° E longitude, its elevation of around 580 meters above sea level contributes to a relatively moderate climate. The surrounding landscape is characterized by undulating hills and plains, transitioning from scrubland and dry deciduous forests to agricultural fields as one moves outwards. Hebli’s proximity to the Western Ghats, though not immediately adjacent, influences regional weather patterns and can occasionally funnel moisture-laden winds. The town sits within a predominantly rural setting, exhibiting a gradual urban–rural gradient as one travels away from the core settlement. While Belagavi, a larger industrial and commercial hub, lies within reasonable commuting distance, Hebli itself maintains a largely agrarian character, with agriculture – primarily sugarcane, maize, and pulses – dominating the surrounding land use. This agricultural activity, coupled with potential localized brick kilns or small-scale industrial units, can contribute to localized air pollution. The town’s location within the broader Karnataka industrial belt, though not directly on a major industrial corridor, means it is susceptible to pollutants transported from further afield. The terrain, with its gentle slopes, can sometimes trap pollutants, particularly during periods of low wind speed, exacerbating local air quality challenges. The lack of significant water bodies immediately adjacent to Hebli limits natural air purification processes.

Hebli's air quality experiences a distinct seasonal cycle dictated by the region's tropical climate, broadly divided into wet and dry seasons. The dry season, typically spanning from October to May, often witnesses a gradual deterioration in air quality. Reduced rainfall and lower humidity contribute to increased dust levels, particularly from agricultural activities like harvesting and land preparation. Temperature inversions, common during the cooler months (December-February), trap pollutants near the ground, leading to stagnant air and elevated concentrations of particulate matter. March and April, with rising temperatures and increased agricultural burning, frequently present the most challenging periods for air quality. The onset of the monsoon season (June-September) brings a significant improvement, as rainfall effectively washes away pollutants and increased wind speeds disperse them. However, the initial monsoon phase can be temporarily impacted by dust storms carried in from the Arabian Sea. Fog, particularly during the cooler months, can also exacerbate air quality issues by reducing visibility and trapping pollutants. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, especially during peak agricultural activity and periods of temperature inversion. Outdoor activities are generally more favorable during the monsoon months, although occasional heavy rainfall can still impact visibility and air quality. The transition periods between seasons often present unpredictable air quality conditions, requiring vigilance and awareness of local conditions.
