Aït Tamlil, nestled within the Béni Mellal-Khénifra region of Morocco, occupies a geographically significant position at approximately 31.48°N, -6.94°W. The town’s setting is characterized by a gently sloping terrain, part of the broader High Atlas foothills, resulting in an elevation of around 850 meters above sea level. This elevation contributes to a cooler climate compared to coastal regions, but also influences air circulation patterns. Aït Tamlil is surrounded by a predominantly agricultural landscape, dominated by olive groves and cereal cultivation, a vital component of the region’s economy. The proximity to these agricultural zones means that seasonal agricultural practices, such as burning crop residue, can contribute to localized air pollution events. The town exhibits a clear urban–rural gradient, transitioning from a concentrated settlement to dispersed rural communities engaged in farming. While not directly adjacent to a major river, the region benefits from groundwater resources and occasional rainfall, impacting humidity levels and influencing atmospheric stability. The nearest significant industrial activity is located in Béni Mellal, approximately 30 kilometers to the north, and while its direct impact is lessened by distance, prevailing winds can occasionally carry pollutants southward. The surrounding landscape, a mix of terraced fields and sparse vegetation, limits the dispersion of pollutants, particularly during periods of calm weather. The valley setting further restricts air movement, potentially trapping pollutants close to the ground. The town’s relatively small size and population (18,091) mean that local emissions from residential heating and limited vehicular traffic are the primary contributors to air quality concerns.

Aït Tamlil’s air quality experiences a distinct seasonal cycle dictated by its Mediterranean climate and regional weather patterns. The dry season, spanning roughly from April to October, typically sees the highest concentrations of particulate matter. This is largely attributable to agricultural practices; the burning of crop residues after harvest, particularly in late summer and early autumn, releases significant amounts of smoke and pollutants into the atmosphere. Calm wind conditions are frequent during this period, hindering the dispersal of these emissions and leading to localized episodes of reduced visibility. Temperature inversions, common during the cooler nights of autumn, trap pollutants near the ground, exacerbating the problem. Spring (March-April) offers a slight improvement as rainfall increases, washing away some pollutants and increasing atmospheric mixing. The wet season, from November to February, generally brings the cleanest air, with frequent rainfall and stronger winds dispersing any accumulated pollutants. However, periods of dense fog, particularly in December and January, can temporarily trap moisture and pollutants, creating localized pockets of poor air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during periods of agricultural burning. Limiting outdoor exertion during these times and monitoring local conditions is advisable. The transition months of March and October present a moderate risk, while the wet winter months generally offer the most favorable conditions for outdoor activities, although fog can occasionally impact visibility and air quality.
