Pedro Betancourt, nestled within the Matanzas Province of Cuba, occupies a geographically significant position on the island’s north-central coast. Located at approximately 22.73°N, 81.29°W, the city’s terrain is characterized by gently rolling hills transitioning into a coastal plain, a typical feature of the Matanzas region. The surrounding landscape is a blend of agricultural lands – primarily sugarcane fields, a dominant feature of Cuban agriculture – and patches of remnant tropical forest. Its proximity to the Bay of Matanzas, a large inlet of the Caribbean Sea, plays a crucial role in local weather patterns and, consequently, air quality. The city sits within a broader urban-rural gradient, with more densely populated areas concentrated closer to Matanzas City, the provincial capital, approximately 15 kilometers to the east. Pedro Betancourt’s location within the historically significant ‘sugar belt’ means that past and present industrial activity, particularly related to sugar processing, has shaped the local environment. While modern industrial practices have evolved, legacy impacts and ongoing agricultural activities contribute to localized air quality considerations. The elevation is relatively low, averaging around 30 meters above sea level, which can exacerbate the trapping of pollutants during periods of stable atmospheric conditions. The prevailing trade winds, while generally beneficial in dispersing pollutants, can occasionally be disrupted, leading to stagnant air masses and increased concentrations of particulate matter and gaseous emissions, especially during transitional seasons. The surrounding agricultural zones, while vital to the Cuban economy, also contribute to air quality through the use of fertilizers and occasional field burning practices.

Pedro Betancourt’s tropical climate dictates a wet and dry season pattern, significantly influencing 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 less frequent rainfall. However, this period can also experience periods of stagnant air, particularly during temperature inversions, where cooler air becomes trapped beneath a layer of warmer air, preventing vertical mixing and concentrating pollutants near the ground. The sugarcane harvest, which often peaks during this time, can contribute to localized particulate matter increases from field preparation and processing. The wet season, from May to October, brings increased rainfall, which naturally helps to cleanse the atmosphere by removing particulate matter. However, the increased humidity can also promote the formation of ground-level ozone, a respiratory irritant, especially during periods of intense solar radiation. The months of June, July, and August are often the most challenging, with a combination of high humidity, intense sunlight, and potential for stagnant air. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit prolonged outdoor activity during these months, particularly during the hottest part of the day. The trade winds, typically strong and consistent, can occasionally weaken or shift direction, leading to periods of localized pollution buildup. While the overall air quality is generally moderate, awareness of these seasonal patterns and meteorological influences is crucial for protecting public health and minimizing exposure to potential air pollutants.
