San José de Aerocuar, nestled within the Venezuelan state of Sucre, occupies a geographically significant position in the eastern part of the country. Located at coordinates 10.6027, -63.3273, the city is situated within a landscape characterized by rolling hills and the foothills of the Venezuelan Coastal Range. The terrain is not dramatically mountainous, but exhibits a gentle undulation that influences local wind patterns and pollutant dispersion. Aerocuar’s elevation, while not extreme, contributes to temperature variations and potential for temperature inversions. The city benefits from relative proximity to the Caribbean Sea, approximately 60km to the north, which introduces maritime influences on humidity and precipitation. However, this proximity doesn’t guarantee consistent sea breezes for pollutant removal. Surrounding Aerocuar are primarily agricultural lands, focused on small-scale farming and livestock raising. While not a heavily industrialized zone, regional agricultural practices, including potential slash-and-burn techniques, contribute to particulate matter. The urban-rural gradient is relatively sharp, with the city centre transitioning quickly to rural landscapes. This impacts air quality as emissions from domestic wood burning and agricultural activities are concentrated near the city, while larger-scale industrial pollution sources are further afield, though still potentially impacting regional air quality.

San José de Aerocuar experiences a distinct wet and dry season, rather than traditional four seasons. Air quality is generally poorer during the dry season (roughly December to April). This is due to reduced rainfall, meaning less atmospheric cleansing of pollutants. Dust and particulate matter from agricultural activities and unpaved roads become more prevalent, exacerbated by drier conditions and increased wind activity. Temperature inversions, common during the cooler nights of the dry season, trap pollutants near ground level. The wet season (May to November) typically brings improved air quality. Frequent rainfall washes away pollutants, and higher humidity can suppress dust. However, even during the wet season, localized pollution events can occur. Increased cloud cover can also contribute to temperature inversions, albeit less frequently. Months to avoid strenuous outdoor activity are February and March, when dust levels are highest. November and December, with the onset of the wet season, offer comparatively better conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor exposure during the dry season and be mindful of agricultural burning practices, which can cause sudden spikes in particulate matter regardless of the season. Monitoring local conditions is crucial.
