Pueblo Nuevo, nestled within the Córdoba department of Colombia, occupies a geographically significant position within the expansive Magdalena River Valley. Located at approximately 8.5008° latitude and -75.5072° longitude, the town’s elevation of around 150 meters above sea level places it within a relatively flat, alluvial plain, characteristic of the valley floor. This terrain, formed by centuries of sediment deposition from the Magdalena River and its tributaries, contributes to a generally humid and warm climate. The surrounding landscape is a mosaic of agricultural lands – primarily sugarcane and banana plantations – interspersed with patches of tropical dry forest. The Magdalena River, though not directly adjacent to Pueblo Nuevo, exerts a considerable influence on the regional climate and hydrology, contributing to high humidity levels. The urban–rural gradient transitions rapidly from the town’s compact core to the intensive agricultural zones that dominate the surrounding countryside. Further afield, the Cordillera Central mountain range looms on the horizon, influencing regional weather patterns and occasionally trapping pollutants. The proximity to agricultural belts means that seasonal burning practices, common in sugarcane cultivation, can significantly impact local air quality. Industrial activity is limited within Pueblo Nuevo itself, but the broader Córdoba department hosts some processing plants, and transport corridors connecting these facilities can contribute to localized pollution episodes. The flat topography and prevailing wind patterns often lead to stagnant air conditions, particularly during periods of reduced wind speed, exacerbating the impact of any emissions.

Pueblo Nuevo experiences a tropical savanna climate, characterized by distinct wet and dry seasons rather than the four traditional seasons. The dry season, typically spanning December to April, often sees a noticeable increase in particulate matter. This is largely attributable to agricultural burning practices employed to clear land for planting and harvesting sugarcane. Reduced rainfall during this period also limits the natural cleansing effect of precipitation, allowing pollutants to accumulate. The wet season, from May to November, brings increased rainfall and higher humidity, generally leading to improved air quality as pollutants are washed from the atmosphere. However, periods of intense rainfall can sometimes lead to flooding, which can temporarily release pollutants from inundated areas. Fog, particularly during the transition months (April/May and October/November), can trap pollutants close to the ground, creating localized episodes of poor air quality. Temperature inversions, though less frequent than in cooler climates, can occasionally occur, especially during the dry season, further hindering pollutant dispersion. During the dry season, sensitive groups such as children, the elderly, and individuals with respiratory conditions should limit prolonged outdoor activity, particularly during the morning hours when burning activities are often most prevalent. The wet season generally offers more favourable conditions for outdoor pursuits, but vigilance is still advised during periods of heavy rainfall or fog. Maintaining awareness of local weather patterns and agricultural practices is crucial for minimizing exposure to potential air quality concerns.
