Ait Lhaj All, nestled within the Fès-Meknès region of Morocco, is a small urban centre situated approximately 20km southwest of the historic city of Fès. The terrain is characterised by rolling hills and agricultural land, part of the broader pre-Rif mountain zone. Located at an elevation of roughly 500 meters, the town benefits from a temperate climate, though its inland position contributes to temperature extremes. The surrounding landscape is dominated by olive groves, cereal farms, and increasingly, small-scale industrial activity linked to the expanding Fès metropolitan area. This proximity to Fès is a key factor influencing air quality in Ait Lhaj All, as pollutants generated by the larger city can be transported by prevailing winds. The urban-rural gradient is relatively sharp; the town itself is compact, quickly giving way to agricultural fields. There are no significant bodies of water immediately adjacent to Ait Lhaj All, but the Sebou River flows nearby, potentially influencing local humidity and atmospheric conditions. Dust from agricultural practices and unpaved roads also contributes to particulate matter in the air. The town’s position within a valley can exacerbate pollution episodes by trapping air masses and hindering dispersion.

Air quality in Ait Lhaj All follows a distinct seasonal pattern. The summer months (June-August) often see a slight deterioration due to increased temperatures and reduced rainfall, leading to higher concentrations of ground-level ozone formed from vehicle emissions and industrial activity around Fès. However, stronger winds can also provide some dispersion. Autumn (September-November) brings a temporary improvement as cooler temperatures and occasional rainfall help to clear the air. Winter (December-February) is typically the period of poorest air quality. Temperature inversions, common in valleys during calm, cold weather, trap pollutants close to the ground, particularly from wood burning for heating and industrial sources. This is exacerbated by reduced sunlight hindering pollutant breakdown. Spring (March-May) sees a gradual improvement as temperatures rise and rainfall increases, washing away accumulated pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter months and periods of calm weather. Dust storms, particularly in spring, can also significantly impact air quality, requiring mask use. Monitoring wind direction is crucial; winds from the northeast often carry pollutants from Fès.
