Tepexi de Rodríguez, nestled within the state of Puebla, Mexico, occupies a geographically complex position within the Sierra Norte de Puebla mountain range. Located at coordinates 18.5833° N, -97.9333° W, the city sits at an elevation of approximately 2,240 meters (7,350 feet) above sea level. This high altitude significantly influences its climate and, consequently, its air quality. The surrounding landscape is characterized by steep slopes covered in pine-oak forests, typical of the cloud forests found in this region. The terrain is deeply dissected by numerous ravines and small rivers, tributaries of the larger Puebla River basin. While not directly adjacent to a major body of water, the city’s water supply relies on these mountain springs and rainfall. The urban-rural gradient is quite sharp; Tepexi de Rodríguez is a relatively small city surrounded by predominantly agricultural land, with small-scale farming of crops like corn, beans, and coffee being prevalent. Limited industrial activity exists within the city itself, but regional transport routes passing through contribute to localised emissions. The valley location, while scenic, can trap pollutants during periods of atmospheric stability, exacerbating air quality concerns. The city’s position within a mountainous region limits air circulation, impacting the dispersion of pollutants.

Air quality in Tepexi de Rodríguez follows a distinct seasonal pattern, largely dictated by meteorological conditions. The dry season, typically from November to April, sees the lowest rainfall and increased dust suspension from agricultural activities and unpaved roads, leading to elevated particulate matter. Temperature inversions are common during these cooler months, trapping pollutants near the ground. February and March often experience the poorest air quality. The onset of the rainy season in May brings a temporary improvement as rainfall washes away pollutants, but increased humidity can also foster mold growth, impacting respiratory health. June to September represents a period of relatively cleaner air, though localized flooding can disrupt transport and potentially release contaminants. October experiences a transitional period with decreasing rainfall and a potential build-up of pollutants. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should exercise caution during the dry season, limiting strenuous outdoor activity on days with visible haze. Monitoring local weather patterns and avoiding peak traffic hours are advisable. The consistent winds from the Gulf of Mexico provide some relief, but their effect is limited by the mountainous terrain.
