Atiquizaya, nestled in the department of Ahuachapán, El Salvador, occupies a geographically significant position within the Central American Volcanic Arc. Located at approximately 13.9667° N, 89.7500° W, the city sits at an elevation of around 680 meters (2,231 feet) above sea level, contributing to a generally cooler climate compared to coastal regions. The surrounding landscape is dominated by rolling hills and volcanic slopes, characteristic of the Ahuachapán region. To the west, the imposing Fuego volcano looms, a constant reminder of the area’s geological activity. The terrain is primarily agricultural, with coffee plantations and smaller farms defining the rural character that gradually transitions into the urban fabric of Atiquizaya. This urban–rural gradient is a key factor influencing air quality; agricultural practices, including the use of fertilizers and potential burning of vegetation, can contribute to localized pollution episodes. While Atiquizaya lacks direct proximity to major bodies of water, the nearby Lempa River basin influences regional weather patterns. The city’s location within a relatively enclosed valley can exacerbate air pollution, particularly during periods of stagnant air. There are no major industrial belts immediately adjacent to Atiquizaya, but the broader Ahuachapán department hosts some light manufacturing and processing facilities, and transportation corridors carrying goods to and from Guatemala can contribute to vehicle emissions impacting the city’s air. The volcanic soils, while fertile, can also be susceptible to erosion, potentially leading to dust pollution during dry periods.

Atiquizaya’s tropical climate dictates a distinct wet and dry season pattern, significantly impacting air quality. The dry season, typically spanning November to April, often brings clearer skies but also heightened particulate matter concentrations. Reduced rainfall means less atmospheric cleansing, and agricultural burning, a common practice for land preparation, becomes more prevalent, releasing smoke and pollutants. Temperature inversions, where cooler air becomes trapped beneath a layer of warmer air, are more frequent during these months, preventing pollutants from dispersing and leading to localized smog. The months of January and February often experience the most challenging air quality conditions. Conversely, the wet season (May to October) brings frequent rainfall, effectively washing pollutants from the atmosphere and generally improving air quality. However, periods of heavy fog, particularly in the mornings, can trap moisture and contribute to localized humidity and potentially, the formation of secondary pollutants. Wind patterns are generally variable, but during the dry season, periods of calm air are common, further hindering pollutant dispersal. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, limiting outdoor activities during peak pollution periods, especially in the mornings. Maintaining indoor air quality through ventilation and air purifiers can also be beneficial. The increased humidity during the wet season can exacerbate allergies for some individuals, so monitoring pollen levels and taking appropriate precautions is advisable.
