Oulad Ouchchih, nestled within the Tanger-Tétouan-Al Hoceïma region of Morocco, occupies a geographically significant position at approximately 35.09°N, 5.95°W. The city’s location, just inland from the Mediterranean coast, influences its microclimate and, consequently, its air quality. Situated at a modest elevation, the surrounding terrain is characterized by rolling hills and agricultural land, transitioning into the Rif Mountains further east. This proximity to both coastal and mountainous landscapes creates a complex interplay of airflows. The Mediterranean Sea provides a source of moisture and can contribute to coastal breezes, but also introduces saline aerosols. The surrounding agricultural zones, while vital for the regional economy, can be sources of particulate matter from farming practices, particularly during planting and harvesting seasons. The urban–rural gradient around Oulad Ouchchih is relatively gradual, with smaller villages and agricultural fields blending into the city’s periphery. While not directly adjacent to major industrial belts, the city’s connection to the larger Tanger-Tetouan metropolitan area means it can be affected by industrial emissions transported by prevailing winds. The local topography, with its gentle slopes, can sometimes trap pollutants, especially during periods of calm weather. The overall landscape is a mosaic of cultivated fields, olive groves, and scattered rural settlements, all contributing to the regional atmospheric dynamics and influencing the city's air quality profile. The city’s relatively small population contributes to a lower baseline pollution load compared to larger urban centers.

Oulad Ouchchih experiences a Mediterranean climate, resulting in distinct seasonal patterns that significantly impact air quality. During the warmer months (June-August), high temperatures and reduced precipitation often lead to stagnant air conditions, particularly in the afternoons. This can exacerbate the effects of any existing pollutants, potentially leading to increased concentrations of particulate matter and ozone. The dry, hot winds blowing from the interior can also carry dust and sand, further degrading air quality. Conversely, the cooler, wetter months (October-March) generally bring improved air quality due to increased rainfall, which helps to wash pollutants from the atmosphere, and stronger, more frequent winds that disperse them. Spring (April-May) and Autumn (September) represent transitional periods, with variable conditions. Fog, common during the cooler months, can trap pollutants near the ground, creating localized air quality concerns. Temperature inversions, where a layer of warm air sits above cooler air, are also possible, preventing vertical mixing and leading to pollutant accumulation. Sensitive groups, such as children, the elderly, and individuals with respiratory conditions, should be particularly cautious during the summer months and on days with fog or temperature inversions. Outdoor activities are generally more favorable during the wetter months, although agricultural burning practices in the surrounding areas can occasionally impact air quality even then. The interplay of these meteorological factors dictates the seasonal air quality narrative in Oulad Ouchchih, requiring adaptive strategies for public health.
