Bobonong, nestled in the Central District of Botswana, occupies a unique geographical position. Situated at coordinates -21.9655, 28.4363, the town lies on a relatively flat plateau, part of the larger Kalahari Basin. The surrounding landscape is predominantly savannah woodland, characterized by acacia trees and grasslands, transitioning into sandy plains further afield. The elevation is around 900-1000 meters above sea level, influencing temperature patterns and atmospheric circulation. While not immediately adjacent to a major body of water, Bobonong is located within a region where seasonal pans (shallow depressions that fill with water during the rainy season) are common, impacting local humidity. The urban character of Bobonong is that of a developing town, serving as a regional administrative and commercial centre for the surrounding rural communities. Agriculture, primarily subsistence farming and livestock rearing, dominates the surrounding areas, contributing to potential dust and biomass burning emissions. The urban-rural gradient is quite pronounced, with a clear distinction between the more concentrated built-up area of Bobonong and the sparsely populated agricultural lands. This gradient, coupled with prevailing wind directions, significantly influences the dispersion of pollutants, concentrating them within the town during periods of calm weather. The lack of significant industrial activity mitigates some pollution sources, but dust from unpaved roads and agricultural practices remain key concerns.

Bobonong experiences a distinct wet and dry season, heavily influencing its air quality. The wet season, typically from November to April, brings relief from dust and particulate matter as rainfall effectively suppresses airborne particles. However, increased humidity can also contribute to the formation of mould spores, potentially impacting respiratory health. The months of December and January often see localized flooding of seasonal pans, which can exacerbate damp conditions. The dry season, spanning May to October, presents the most challenging air quality conditions. During this period, persistent drought conditions and increased agricultural activity lead to higher levels of dust and smoke from controlled burns used for land clearing. Wind speeds tend to be higher during the dry season, potentially transporting dust from surrounding areas into the town. Temperature inversions, common during the cool mornings of June and July, trap pollutants near the ground, worsening air quality. August and September are particularly prone to dust storms. Sensitive groups, including children, the elderly, and individuals with respiratory illnesses, should limit outdoor activity during these months. Wearing masks and keeping windows closed can help mitigate exposure. The transition months of November and April offer the most favourable conditions for outdoor activities, with moderate temperatures and reduced pollution levels.
