Keshod is situated within the fertile plains of the Saurashtra peninsula in Gujarat, serving as a vital commercial node for the surrounding agrarian landscape. Positioned in the Junagadh district, the town is characterized by a flat, semi-arid terrain that transitions seamlessly into the vast, biodiverse expanse of the Gir Forest. This regional positioning creates a unique urban-rural gradient where the town’s dense commercial core is buffered by sprawling fields of groundnut and cotton. The proximity to the Arabian Sea, while not directly coastal, allows for periodic maritime breezes that help ventilate the urban canopy, though the inland distance limits this cleansing effect during stagnant weather. The surrounding landscape is predominantly low-lying, which means there are few natural topographical barriers to prevent the lateral movement of pollutants from nearby industrial clusters or agricultural zones. However, the proximity to the Gir forest acts as a critical carbon sink, mitigating some of the local emissions. Air quality in Keshod is heavily influenced by this intersection of agricultural activity and urban growth. The prevalence of unpaved roads in the periphery contributes to high levels of suspended particulate matter, especially during the dry months. As a trading hub, the influx of heavy transport vehicles adds a layer of combustion-based pollutants to the atmosphere. Consequently, the city's air quality profile is a complex blend of organic agricultural dust and urban vehicular exhaust, shaped by its specific placement in the Gujarat hinterland.

The air quality narrative in Keshod is dictated by the rhythmic oscillation of the tropical semi-arid climate. During the scorching summer months, from March to June, the atmosphere is dominated by high temperatures and desiccated soils, leading to elevated levels of coarse mineral dust. Strong convective currents often lift these particles, creating a hazy horizon. As the southwest monsoon arrives between June and September, the city experiences a dramatic atmospheric cleansing. Heavy precipitation effectively scrubs the air of particulate matter, marking the period of lowest pollution and highest visibility, making it ideal for outdoor activities. However, the transition into the post-monsoon period in October and November introduces a new challenge: agricultural residue burning. As farmers clear fields for the next cycle, smoke plumes often linger, exacerbated by decreasing wind speeds. The winter months, from December to February, bring the most precarious conditions. Cooler temperatures trigger nocturnal temperature inversions, where a layer of warm air traps pollutants close to the ground. This phenomenon, combined with occasional morning fog, concentrates vehicular emissions and domestic smoke, posing risks to those with chronic respiratory conditions. Sensitive groups, including the elderly and children, should limit prolonged outdoor exertion during these stagnant winter mornings. To maintain respiratory health, residents are encouraged to favor the monsoon window for intensive outdoor work and exercise caution during the late-autumn burning season and the winter inversion peaks, ensuring a mindful approach to the city's seasonal atmospheric shifts.
