Sabanagrande, nestled within the Atlántico Department of Colombia, occupies a low-lying coastal plain at approximately 10.8000°N, -74.7500°W. The city’s geography is fundamentally shaped by its proximity to the Caribbean Sea, roughly 20 kilometers to the north, and its position within the Magdalena River Delta region. Terrain is predominantly flat, characteristic of alluvial plains, with minimal elevation changes. This flatness contributes to limited natural air dispersion. Sabanagrande is situated within a transitional zone between urban and rural landscapes, with agricultural activities – primarily banana, plantain, and yucca cultivation – dominating the surrounding areas. To the south and east, the land gradually transitions into more extensive agricultural zones. While Sabanagrande itself isn’t a major industrial hub, its location along key transport routes connecting Barranquilla (a significant industrial port city) and other inland regions means it experiences traffic-related emissions. The urban-rural gradient is relatively sharp, with a noticeable increase in population density and built-up areas concentrated around the city center. This concentration, coupled with the prevailing winds often channeling pollutants along the flat terrain, can exacerbate localized air quality issues. The warm, humid climate further influences pollutant behaviour, promoting the formation of secondary pollutants.

Sabanagrande experiences a bimodal rainfall pattern, defining its ‘seasons’ rather than traditional four-season cycles. The drier periods, typically from December to April, coincide with increased dust and particulate matter in the air, driven by agricultural activities and drier road conditions. Winds from the Guajira Peninsula can carry Saharan dust, further impacting air quality during these months. February and March are often the dustiest, potentially aggravating respiratory conditions. The wetter seasons, from May to November, generally offer improved air quality due to rainfall scavenging pollutants. However, increased humidity can also promote the formation of mold and fungal spores, impacting indoor air quality. September and October, peak months for rainfall, see the lowest levels of particulate matter. Temperature inversions, common during the calmer nights of the drier season, trap pollutants near ground level. Sensitive individuals – children, the elderly, and those with pre-existing respiratory illnesses – should limit strenuous outdoor activity during the drier months and monitor their health closely. Fog, prevalent during the transition periods, can also exacerbate respiratory issues by trapping pollutants. Overall, the wetter months offer more favourable conditions for outdoor activity.
