Jagüey Grande, nestled in the Matanzas Province of Cuba, occupies a geographically significant position within the island’s central plain. The city’s coordinates (22.5292, -81.1325) place it relatively close to the northern coast, approximately 15 kilometers inland from the Bahia de Matanzas. This proximity to the sea influences local weather patterns and contributes to humidity levels. The terrain is predominantly flat, characteristic of the region’s alluvial plains formed by the Yumurí River and its tributaries. Surrounding Jagüey Grande is a landscape dominated by agricultural land, primarily sugarcane and citrus groves, reflecting the historical and ongoing economic importance of these crops to the region. The urban-rural gradient is relatively sharp, transitioning quickly from the city’s core to expansive agricultural fields. While not a major industrial hub, the presence of processing facilities related to agriculture, alongside smaller-scale manufacturing, contributes to localised emissions. The prevailing winds, generally from the northeast trade winds, play a crucial role in dispersing pollutants, but can also concentrate them during periods of stagnation. The flat topography limits natural ventilation, potentially exacerbating air quality issues during calm conditions. The city’s location within a tropical climate means consistent warmth and high humidity, impacting pollutant chemistry and dispersion.

Jagüey Grande experiences a distinct wet and dry season, heavily influencing its air quality. The dry season, spanning November to April, typically sees lower rainfall and increased dust from agricultural activities, leading to elevated particulate matter concentrations. The northeast trade winds are generally stronger during this period, offering some dispersion, but can also carry Saharan dust plumes impacting visibility and respiratory health. February and March are often the driest months, potentially worsening conditions. The wet season, from May to October, brings increased rainfall which effectively washes pollutants from the air, resulting in generally improved air quality. However, increased humidity can promote the formation of ground-level ozone, particularly during hot, sunny days. September and October, coinciding with the peak of the hurricane season, can experience periods of stagnant air and localised flooding, potentially concentrating pollutants. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit strenuous outdoor activity during the dry season and monitor conditions closely during periods of high humidity. Maintaining good ventilation indoors is crucial year-round, and staying informed about weather forecasts is essential for proactive health management.
