Kyotera, a small town in Rakai District, Uganda, is situated at approximately -0.6317 latitude and 31.5433 longitude. The town occupies a gently undulating landscape within the Lake Victoria basin, at an elevation of roughly 1,200 meters above sea level. This altitude moderates temperatures but doesn’t eliminate the influence of the equatorial climate. Kyotera’s air quality is significantly shaped by its rural-urban gradient; it’s transitioning from a predominantly agricultural area to a small urban centre. Surrounding the town are extensive agricultural lands, primarily smallholder farms cultivating bananas, coffee, and other staples. These agricultural practices, while vital to the local economy, contribute to particulate matter pollution through land clearing, burning of crop residues, and dust from tilling. The proximity to Lake Victoria, approximately 50km to the east, introduces humidity and can contribute to localised fog formation, trapping pollutants. While Kyotera lacks heavy industry, the increasing use of charcoal for cooking and wood fuel for heating, coupled with vehicle emissions from the growing transport network connecting it to larger towns like Masaka, are emerging pollution sources. The terrain, while not mountainous, influences wind patterns, creating localised areas of stagnant air, particularly in the valleys.

Kyotera experiences a bimodal rainfall pattern, defining its ‘seasons’ as wet and dry. Air quality is generally better during the wet seasons (March-May and September-November) due to rainfall scavenging pollutants from the atmosphere. However, increased humidity can also exacerbate fungal spore concentrations, impacting respiratory health. The first dry season (June-August) sees a noticeable increase in dust and particulate matter as agricultural activities intensify and roads become drier. This is often the period with the poorest air quality. The short dry season (December-February) is characterised by higher temperatures and increased use of biomass fuels for cooking and heating, leading to elevated levels of indoor and outdoor air pollution. Temperature inversions, common during the cooler nights of the dry season, trap pollutants near ground level. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit strenuous outdoor activity during these periods. Months to favour for outdoor activity are typically April and October, during the inter-seasonal periods with moderate rainfall and temperatures. Monitoring local fire activity is crucial, as agricultural burning can rapidly degrade air quality regardless of the season.
