Boussé is situated within the Plateau-Central region of Burkina Faso, embodying the quintessential characteristics of a Sahelian settlement. The town sits upon a relatively flat, undulating plateau, where the terrain is dominated by sparse savanna vegetation and lateritic soils. This geographic positioning places Boussé in a transitional zone between the more humid southern regions and the arid northern reaches of the country. The urban character is defined by a low-density sprawl that blends seamlessly into a vast agricultural hinterland, creating a sharp urban-rural gradient where domestic activities frequently intersect with farming practices. Its proximity to regional transport corridors facilitates the movement of goods but also increases the prevalence of road-borne particulate matter. The absence of significant topographic barriers, such as mountains or dense forests, means that the town is entirely exposed to the sweeping atmospheric currents of the West African interior. Consequently, air quality is heavily dictated by the surrounding landscape's susceptibility to wind erosion. The sparse ground cover allows surface dust to be easily lofted into the atmosphere, while the town's position within the interior plateau ensures that it remains a catchment for long-range mineral dust. With limited permanent water bodies to provide a cooling or scrubbing effect on the air, the atmosphere often remains dry and laden with aerosols, making the interplay between the flat terrain and the arid climate the primary driver of its local environmental air profile.

The air quality narrative in Boussé is dictated by the dramatic oscillation between the dry and wet seasons. From November to May, the town enters its most challenging atmospheric phase, dominated by the Harmattan. This northeasterly trade wind transports massive quantities of mineral dust from the Sahara Desert, leading to a persistent haze that reduces visibility and spikes particulate matter concentrations. During the peak of the dry season, typically January and February, temperature inversions can trap pollutants near the ground, exacerbating the impact of biomass burning from traditional cooking fires and agricultural clearing. These months are the most hazardous for sensitive groups, including children and the elderly, who are advised to limit prolonged outdoor exertion and utilize protective face coverings. Conversely, the arrival of the monsoon rains from June to October brings a profound atmospheric cleansing. Frequent precipitation triggers wet deposition, effectively scrubbing the air of suspended dust and aerosols, leading to the cleanest air of the year. This wet period is the ideal time for outdoor activity and respiratory recovery. However, the transition months of May and June can see sudden dust storms before the rains stabilize. For those with chronic respiratory conditions, the transition into the Harmattan period requires proactive health management, as the combination of extreme dryness and high dust loads can trigger severe asthma or bronchitis, making the wet season the only reliable window for optimal air quality.
