San José Acatempa, nestled within the Jutiapa department of Guatemala, occupies a geographically significant position in the country’s southeastern region. Located at coordinates 14.2667, -90.1333, the city is characterized by a terrain of rolling hills and valleys, typical of the volcanic highlands. Its elevation, approximately 1,500 meters (4,921 feet) above sea level, influences both temperature and atmospheric circulation. The surrounding landscape is predominantly agricultural, dominated by coffee plantations and subsistence farming, with pockets of dry forest. While not directly adjacent to a major body of water, the city lies within a watershed feeding into regional river systems. The urban-rural gradient is quite sharp; San José Acatempa itself is a relatively small urban center, quickly transitioning to rural agricultural lands. This proximity to agricultural activity is a key factor influencing air quality, as agricultural burning and pesticide use contribute to particulate matter and gaseous pollutants. Limited industrial activity within the city itself means that long-range transport of pollutants from larger urban centers like Guatemala City, combined with local agricultural practices, are the primary drivers of air quality concerns. The valley location can also trap pollutants, exacerbating air quality issues during periods of calm weather.

San José Acatempa experiences a distinct wet and dry season, heavily influencing air quality patterns. The dry season, typically from November to April, sees a significant deterioration in air quality. Reduced rainfall means less atmospheric cleansing, and agricultural burning for land preparation becomes widespread, releasing substantial amounts of particulate matter (PM2.5 and PM10). Stable atmospheric conditions during this period, coupled with temperature inversions common in valleys, trap pollutants near the ground. February and March are generally the worst months for air quality. The onset of the wet season in May brings a marked improvement. Frequent rainfall washes pollutants from the atmosphere, and increased humidity suppresses dust. However, even during the wet season, localized pollution events can occur due to ongoing agricultural activities and vehicle emissions. September and October, towards the end of the wet season, can see a slight increase in pollutants as fields dry out. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during the dry season, particularly in February and March. Wearing masks can offer some protection. Monitoring local conditions and staying indoors on particularly hazy days is advisable.
