Guanta, nestled in Anzoátegui State, Venezuela, occupies a crucial coastal position along the Caribbean Sea at approximately 10.2383°N, -64.5917°W. The city’s terrain is relatively flat, characteristic of the coastal plains, with a low elevation that contributes to limited natural air dispersion. Guanta’s urban character is defined by its port activity, serving as a significant hub for maritime trade and industrial processing. This proximity to the sea, while economically vital, also introduces the potential for salt spray and humidity to influence pollutant behaviour. Surrounding Guanta are agricultural lands, primarily dedicated to fruit and vegetable cultivation, and further inland, the foothills of the Venezuelan Coastal Range begin to rise. The urban-rural gradient is relatively sharp, transitioning quickly from the concentrated industrial and port areas of Guanta to more sparsely populated agricultural zones. The city’s location within a tropical climate zone means consistent warmth and humidity, but also limited prevailing winds that can effectively flush out pollutants. Industrial activity concentrated around the port, including petrochemical processing and cargo handling, is a primary source of localised emissions, impacting air quality particularly in the immediate vicinity. The lack of significant topographical features to break up wind patterns exacerbates the potential for pollutant build-up.

Guanta experiences a distinct wet and dry season rather than traditional four seasons. The dry season, typically from February to May, sees a concentration of particulate matter due to reduced rainfall and increased dust from drier agricultural lands. This period often coincides with increased industrial activity as shipping lanes are calmer. Winds are generally lighter during these months, hindering pollutant dispersion. Conversely, the wet season, spanning June to November, brings relief through rainfall that washes pollutants from the air, improving air quality. However, high humidity can also promote the formation of secondary pollutants. December and January represent a transitional period with variable rainfall. Temperature inversions, common during the calmer nights of the dry season, trap pollutants near ground level, worsening conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during the drier months, particularly in areas near the port. The months of September and October, while still within the wet season, often experience calmer conditions and can see a resurgence of localised pollution. Monitoring wind direction is crucial; onshore breezes can carry pollutants from industrial sources directly into residential areas.
