Cabarete, nestled within the Cibao Norte province of the Dominican Republic, occupies a unique coastal position that significantly shapes its air quality profile. Located at approximately 19.75°N, 70.41°W, the town sits on a relatively flat coastal plain, just inland from the Atlantic Ocean. This proximity to the sea provides a constant source of maritime breezes, which generally contribute to air ventilation, but can also introduce salt spray and, occasionally, pollutants transported from distant sources. The surrounding landscape is a blend of lush tropical vegetation, including palm groves and mango orchards, characteristic of the Cibao Valley. To the west, the terrain gradually rises, transitioning into rolling hills and eventually the Cordillera Central mountain range, though this is a considerable distance away. The Cibao Valley itself is a major agricultural zone, producing sugarcane, bananas, and other crops; while direct emissions from large-scale agriculture are limited, dust from tilling and harvesting can become a localized air quality concern. There are no major industrial belts immediately adjacent to Cabarete, but the larger city of Santiago, with its industrial activity, lies approximately 40 kilometers to the south, potentially influencing regional air quality patterns. The urban-rural gradient is relatively sharp; Cabarete is a concentrated tourist hub, surrounded by agricultural land and smaller rural communities. The elevation is low, averaging around 10 meters above sea level, which can exacerbate temperature inversions under certain meteorological conditions, trapping pollutants closer to the ground. The prevailing trade winds generally blow from the east, influencing the dispersal of any localized emissions.

Cabarete’s tropical climate dictates a wet and dry season pattern, profoundly impacting its air quality. The dry season, typically spanning December to April, often sees clearer skies and generally improved air quality due to reduced rainfall and lower humidity. However, this period can also experience periods of stagnant air, particularly when high-pressure systems dominate, leading to a build-up of localized pollutants. Dust from agricultural activities, especially during the harvest season (January-March), can become a noticeable issue. The wet season, from May to November, brings frequent rainfall and higher humidity, which naturally scavenges airborne particles, leading to a reduction in particulate matter. However, heavy downpours can temporarily increase levels of mold spores and other biological pollutants. During the transition months (April and November), unpredictable weather patterns can lead to fluctuating air quality. Fog, particularly in the early morning hours during the drier months, can trap pollutants near the surface. The trade winds, while generally beneficial, can occasionally weaken, allowing for the accumulation of emissions. Sensitive groups, such as asthmatics and those with respiratory conditions, should be mindful of agricultural burning during the dry harvest season and monitor for increased pollen counts during the transition months. While the wet season generally improves air quality, those with mold allergies should exercise caution following heavy rainfall. Outdoor activities are generally most favorable during the drier months, avoiding peak agricultural activity periods.
