Jaramijó, nestled in the Manabí province of Ecuador, occupies a geographically significant position within the country’s coastal lowlands. Located at approximately -0.9487° latitude and -80.6363° longitude, the city’s terrain is predominantly flat, characteristic of the Ecuadorian coast, with gentle slopes leading towards the Pacific Ocean, roughly 15 kilometers to the west. This proximity to the ocean significantly influences local climate and, consequently, air quality. The surrounding landscape is a mosaic of small-scale agriculture, primarily focused on banana and sugarcane cultivation, interspersed with patches of mangrove forests along the coastal fringes. The urban–rural gradient is relatively sharp; Jaramijó transitions quickly from a small, concentrated urban area to agricultural fields and then to the coastal ecosystem. Elevation is low, averaging around 10 meters above sea level, which limits atmospheric dispersion of pollutants. While Jaramijó isn't directly adjacent to major industrial belts, it benefits from its position along key transportation routes, facilitating the movement of goods and potentially contributing to localized emissions from vehicular traffic. The Río Cojimíes flows nearby, providing a water source but also potentially carrying pollutants from upstream agricultural runoff. The prevailing easterly trade winds, common along the Ecuadorian coast, play a crucial role in ventilating the area, though their effectiveness can be diminished by certain weather patterns. The flat topography and coastal location combine to create a setting where localized pollution sources can have a disproportionate impact on air quality.

Jaramijó experiences a tropical climate with distinct wet and dry seasons, profoundly impacting its air quality profile. The wet season, typically spanning from November to April, brings consistent rainfall and increased humidity. While the rain itself can help cleanse the atmosphere by removing particulate matter, the increased humidity can trap pollutants closer to the ground, particularly during periods of reduced wind. The dry season, from May to October, is characterized by lower rainfall and higher temperatures. This often leads to a build-up of pollutants, especially during periods of stagnant air. Temperature inversions, where a layer of warm air sits above cooler air near the ground, are more frequent during the dry season, preventing vertical mixing and trapping pollutants. Fog, common during the early morning hours in the dry season, further exacerbates this issue by reducing visibility and concentrating pollutants. Agricultural burning, a common practice during land clearing and sugarcane harvesting, is most prevalent towards the end of the dry season and early wet season, significantly contributing to particulate matter pollution. Outdoor activities are generally more favorable during the wet season, particularly during and immediately after rainfall. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, especially during periods of fog or stagnant air, and avoid strenuous outdoor activity during agricultural burning season. The interplay of humidity, temperature, and wind patterns dictates the fluctuating air quality throughout the year, demanding adaptive strategies for public health.
