Colombia, in the Las Tunas province of Cuba, is a city nestled within a largely rural landscape. Situated at coordinates 20.9906, -77.4158, the city occupies a relatively flat terrain, typical of much of the Cuban central plain. Its elevation is modest, contributing to limited natural dispersion of pollutants. The city’s position is inland, approximately 25 kilometers from the northern coast and the Bahia de Camagüey, a significant body of water. This distance moderates the immediate influence of sea breezes, but humidity remains high. Surrounding Colombia are extensive agricultural zones, primarily dedicated to sugarcane and citrus cultivation, with associated agricultural burning practices. While not a major industrial hub itself, the region experiences some industrial activity related to sugar processing and food production. The urban-rural gradient is quite pronounced; the city centre is densely populated, but quickly transitions to agricultural land. This proximity to agricultural sources, combined with the flat topography and limited wind flow, creates conditions conducive to localised air pollution events. The prevailing winds are generally from the east, potentially carrying pollutants from other agricultural areas. The city’s growth has been relatively slow, but increasing vehicle traffic and domestic fuel use are emerging concerns for air quality.

Colombia, Cuba experiences a distinct wet and dry season rather than traditional four seasons. Air quality generally improves during the wet season (May to October) due to increased rainfall which effectively washes particulate matter from the atmosphere. However, high humidity can also trap pollutants near the ground. The driest months, November to April, typically see the poorest air quality. This is largely due to increased agricultural burning for sugarcane harvesting, a common practice during this period. February and March are often the most problematic months. Temperature inversions, where a layer of warm air traps cooler air below, are common during the drier months, exacerbating pollution build-up. Wind patterns are generally weaker during the dry season, further limiting dispersion. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during these peak pollution periods. The transition months (April/May and October/November) can be unpredictable, with fluctuating air quality. Monitoring local conditions is crucial. Increased dust from agricultural activities also contributes to poorer air quality during the dry season. Local meteorological conditions heavily influence daily pollution levels.
