La Lisa, a municipality within the La Habana province of Cuba, occupies a strategically important position just southwest of the capital city, La Habana. Its coordinates, 23.0247° N, -82.4631° W, place it within a relatively low-lying coastal plain, characterized by gently undulating terrain. The municipality’s landscape is a blend of urban development and remnants of its agricultural past, transitioning from densely populated residential areas to more rural fringes. The proximity to the Gulf of Mexico significantly influences local weather patterns and, consequently, air quality. To the north, La Lisa borders the expansive bay of La Habana, a major port and industrial hub, while to the south, it gradually merges with agricultural lands, including sugarcane fields and smaller farms. This juxtaposition of industrial activity and agricultural zones creates a complex interplay of potential pollution sources. The elevation is generally low, rarely exceeding 30 meters above sea level, which can exacerbate the trapping of pollutants during periods of stable atmospheric conditions. The urban–rural gradient is relatively sharp, with the core of La Lisa exhibiting high population density and associated vehicular emissions, while the periphery retains a more agrarian character. The surrounding landscape is dominated by tropical vegetation, providing some natural filtration, but also contributing to seasonal pollen loads. The municipality’s location within the broader Havana metropolitan area means it shares in the region’s overall industrial and transportation-related air quality challenges, amplified by its specific geographic features.

La Lisa’s tropical climate dictates a wet and dry season pattern, profoundly impacting air quality throughout the year. The dry season, typically spanning November to April, often sees a build-up of pollutants due to reduced rainfall and lower wind speeds. This period is characterized by increased dust from construction and agricultural activities, coupled with stagnant air masses that can trap emissions from vehicles and the nearby industrial zones. Temperature inversions, common during the cooler months of December and January, further exacerbate this issue, preventing pollutants from dispersing vertically. The wet season, from May to October, brings frequent rainfall and increased humidity, which naturally cleanse the atmosphere, washing away particulate matter and reducing overall pollution levels. However, heavy rainfall can also lead to increased mold and fungal spores, impacting air quality for sensitive individuals. The summer months (July and August) are often hot and humid, with occasional sea breezes that can provide some ventilation, but also carry salt and other coastal aerosols. During these months, ozone formation, driven by sunlight and high temperatures, can be a concern. It’s advisable for individuals with respiratory conditions to limit strenuous outdoor activity during the dry season, particularly during periods of stagnant air. The transition months (April/May and October/November) often experience variable conditions, with periods of both high and low pollution, making it crucial to monitor local conditions. Sensitive groups, including children, the elderly, and those with pre-existing respiratory illnesses, should exercise caution and consult local health advisories throughout the year.
