Camagüey, Cuba, a city steeped in history and architectural charm, occupies a central position within the island, specifically in the Camagüey Province. Its coordinates (21.5294, -78.2228) place it on relatively flat terrain, characteristic of much of the province, with an average elevation of around 30 meters above sea level. This low-lying geography, combined with its inland location approximately 60 kilometers from the northern coast, influences its air quality dynamics. The surrounding landscape is predominantly agricultural, featuring extensive cattle ranching and sugarcane cultivation, alongside pockets of deciduous forests. While not heavily industrialized, Camagüey does possess some light manufacturing and processing facilities related to agriculture. The urban-rural gradient is relatively gradual, with agricultural land intermingling with residential areas on the city’s periphery. The city itself is known for its labyrinthine street plan, intentionally designed by its Spanish colonial founders to confuse potential invaders. This layout, while historically strategic, can contribute to localized air stagnation in certain areas. The prevailing winds are generally from the northeast trade winds, but local topography can create microclimates and affect pollutant dispersion. The lack of significant elevation limits atmospheric mixing, potentially trapping pollutants during calm conditions. The nearby Sabana River and other smaller waterways contribute to humidity, which can influence chemical reactions in the atmosphere.

Camagüey experiences a tropical climate with distinct wet and dry seasons, profoundly impacting air quality. The dry season, spanning November to April, generally presents better air quality. Lower humidity and consistent trade winds facilitate pollutant dispersion. However, agricultural burning, common during this period to prepare fields for planting, can lead to temporary spikes in particulate matter, particularly in rural areas surrounding the city. February and March are typically the most favourable months for outdoor activities. The wet season, from May to October, brings increased rainfall and higher humidity. While rainfall can help cleanse the atmosphere, the increased moisture also promotes the formation of ground-level ozone, especially during hot, sunny days. August and September, coinciding with the peak of the hurricane season, can experience periods of stagnant air and increased pollutant concentrations if storms disrupt wind patterns. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit strenuous outdoor activity during these months. The increased humidity can also exacerbate mold growth, contributing to indoor air quality issues. Monitoring local weather patterns and avoiding outdoor exertion during peak heat and humidity is crucial for maintaining respiratory health. The transition months of April/May and October/November often see fluctuating conditions, requiring increased vigilance.
