Cayo Mambí, nestled within the Holguín province of Cuba, presents a unique geographic setting influencing its air quality. Situated at coordinates 20.6647, -75.2814, the city occupies a relatively low-lying terrain, typical of the eastern Cuban landscape. The surrounding area is characterised by rolling hills and fertile agricultural lands, primarily dedicated to sugarcane and fruit cultivation. Its proximity to the Bahía de Nipe, a large natural bay, introduces coastal influences, including sea breezes that can both disperse and concentrate pollutants depending on atmospheric conditions. While not heavily industrialised, Holguín province does have some nickel mining and processing operations further inland, and prevailing winds can transport particulate matter towards Cayo Mambí. The urban-rural gradient is fairly sharp; the city itself is compact with a population of 22,286, quickly transitioning to agricultural fields and forested areas. This proximity to natural vegetation generally aids in air purification, but seasonal agricultural burning can contribute to localised pollution spikes. The city’s location within the trade wind belt means consistent airflow, but topographic features can create localised wind shadows, trapping pollutants. Understanding these geographical factors is crucial for assessing and mitigating air quality concerns in Cayo Mambí.

Cayo Mambí experiences a distinct wet and dry season, heavily influencing air quality. The dry season, spanning November to April, typically sees lower rainfall and increased dust from agricultural activities and unpaved roads, leading to elevated particulate matter concentrations. January and February are often the driest months, and consequently, can present the poorest air quality. Stable atmospheric conditions during this period can also contribute to temperature inversions, trapping pollutants near ground level. The wet season, from May to October, brings relief through rainfall which effectively washes away airborne particles. However, increased humidity can also promote the formation of secondary pollutants. September and October, coinciding with the peak of the hurricane season, can experience periods of stagnant air followed by rapid clearing after rainfall. Sensitive groups, including children and the elderly, should limit strenuous outdoor activity during the dry season, particularly on windy days. During the wet season, while overall air quality improves, mould spores can become prevalent, posing a risk to those with respiratory sensitivities. Monitoring weather patterns and local agricultural practices is key to anticipating pollution fluctuations.
