Morón, situated in the province of Ciego de Ávila, Cuba, occupies a geographically significant position within the island’s central region. Located at approximately 22.1108° latitude and -78.6278° longitude, the city lies relatively close to the northern coast, influencing its climate and air quality dynamics. The surrounding landscape is predominantly characterized by low-lying plains, typical of the Cuban archipelago, with gently undulating terrain. Morón is strategically positioned near the vast Ciego de Ávila plains, a major agricultural zone dedicated to sugar cane cultivation and livestock farming. This proximity introduces potential sources of particulate matter, particularly during harvest seasons when burning of agricultural residues can occur. The city’s elevation is minimal, contributing to a tendency for pollutants to accumulate, especially under stable atmospheric conditions. The nearby Jobabo River provides a crucial water source and influences local humidity, which can impact the dispersion of airborne contaminants. While not directly coastal, Morón benefits from sea breezes, which can, at times, help to ventilate the city. The urban–rural gradient transitions relatively quickly, with agricultural lands enveloping the city limits. Industrial activity is limited, primarily focused on sugar processing and related industries, though these contribute localized emissions. The flat topography and prevailing wind patterns, often influenced by the Caribbean Sea, play a crucial role in determining the city’s air quality profile, often leading to periods of stagnation and localized pollution episodes.

Morón’s tropical climate dictates a distinct wet and dry season pattern, significantly impacting air quality throughout the year. The dry season, typically spanning from November to April, often sees a reduction in overall air pollution due to lower humidity and increased wind speeds. These winds, frequently originating from the Atlantic, help to disperse pollutants, leading to improved air quality. However, the dry season also coincides with the sugar cane harvest, a period where controlled burns of fields can release substantial amounts of particulate matter, creating localized air quality concerns. The wet season, from May to October, brings increased rainfall and higher humidity. While rain naturally helps to cleanse the atmosphere by removing particulate matter, the increased humidity can trap pollutants closer to the ground, particularly during periods of calm weather. Temperature inversions, though less frequent than in colder climates, can still occur, trapping emissions near the surface. Fog, a relatively uncommon occurrence, can exacerbate this effect. Months like July and August, with their high humidity and potential for stagnant air, may present challenges for sensitive individuals. During these periods, those with respiratory conditions, the elderly, and young children should limit prolonged outdoor exertion. The agricultural cycle dictates that late November to early December often sees a peak in particulate matter due to harvest activities. Conversely, February and March generally offer the most favourable air quality conditions, characterized by drier air and more consistent ventilation.
