Aguadas, nestled within the department of Caldas, Colombia, occupies a geographically significant position in the Paisa region’s coffee-growing heartland. Located at approximately 5.6167° latitude and -75.4667° longitude, the city sits at an elevation of around 1,980 meters (6,500 feet) above sea level, contributing to a consistently cool, temperate climate. The surrounding landscape is dominated by the Andean foothills, characterized by steep slopes, lush green valleys, and extensive coffee plantations. This terrain significantly influences air circulation patterns; the valley location can trap pollutants, particularly during periods of low wind. Aguadas is situated near the Río Claraval, a vital water source, though its direct impact on air quality is minimal. The urban fabric of Aguadas is relatively compact, exhibiting a clear urban–rural gradient as one moves outwards towards the surrounding agricultural lands. While not directly adjacent to major industrial belts, the region’s agricultural activity, particularly coffee processing and related activities, can contribute to localized emissions. The proximity to larger urban centers like Manizales and Pereira means Aguadas is susceptible to the indirect impacts of regional pollution transport. The mountainous terrain and valley setting combine to create a microclimate where air quality can be highly variable, influenced by both local sources and broader regional atmospheric conditions. The steep slopes also limit dispersion of pollutants, potentially exacerbating issues during unfavorable meteorological conditions.

Aguadas experiences a tropical rainforest climate with distinct wet and dry seasons, rather than the four traditional seasons. The wet season, typically spanning from April to October, brings consistent rainfall and high humidity. During this period, air quality generally improves due to frequent precipitation washing away particulate matter and increased atmospheric mixing from rainfall-induced convection. However, periods of prolonged fog, common during the wet season, can trap pollutants near the ground, leading to localized air quality concerns. The dry season, from November to March, is characterized by lower rainfall and increased sunshine. This often leads to temperature inversions, particularly in the mornings, where cooler air becomes trapped in the valleys, preventing the vertical dispersion of pollutants. Agricultural burning, a common practice during land clearing and crop residue management in the surrounding coffee plantations, significantly contributes to particulate matter pollution during the dry season. The combination of temperature inversions and agricultural emissions often results in poorer air quality during these months. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly in the mornings. Outdoor activities are generally more favorable during the wet season, although periods of dense fog should be avoided. The prevailing winds, though generally light, can shift, impacting pollutant distribution and creating localized hotspots. Understanding these seasonal patterns is crucial for managing air quality and protecting public health in Aguadas.
