Souk Et-Tleta des Oulad Hamdane, nestled within the Casablanca-Settat region of Morocco, occupies a geographically significant position. The city itself is situated on the coastal plains of western Morocco, approximately 30km southeast of Casablanca, the nation’s economic hub. The terrain is relatively flat, characteristic of the Atlantic coastal plain, gradually rising inland towards the foothills of the High Atlas Mountains. This proximity to the Atlantic Ocean exerts a moderating influence on the climate, but also contributes to humidity and potential for sea breezes that can trap pollutants. The surrounding landscape is a mix of agricultural land – primarily cereal crops and olive groves – and increasingly, peri-urban development extending from Casablanca. This urban-rural gradient is crucial; the expansion of Casablanca’s industrial zones and associated traffic contributes significantly to regional air pollution that impacts Souk Et-Tleta. The city’s elevation is low, around 50m above sea level, which limits atmospheric dispersion of pollutants. The lack of significant topographical features to break up airflow exacerbates this issue. Dust from the surrounding agricultural areas and potential Saharan dust events further complicate the air quality profile, particularly during dry periods. The city’s location within a developing industrial corridor necessitates careful monitoring and mitigation strategies.

Air quality in Souk Et-Tleta des Oulad Hamdane follows a distinct seasonal pattern. Winter (December-February) often sees poorer air quality due to temperature inversions – cool, stable air trapping pollutants near the ground – and increased use of solid fuels for heating. Calm wind conditions exacerbate this. Spring (March-May) brings a temporary improvement as increased rainfall washes away particulate matter and winds become more frequent. However, agricultural burning of crop residue can cause localised spikes in pollution. Summer (June-August) is generally the clearest period, with consistent sea breezes aiding dispersion, though Saharan dust incursions are common, raising particulate matter levels. These dust events can significantly impact respiratory health. Autumn (September-November) marks a transition period. The cessation of summer breezes and the return of stable atmospheric conditions lead to a gradual decline in air quality. Increased traffic associated with the harvest season and the start of the heating season contribute to this. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter and autumn months, and take precautions during Saharan dust events. Monitoring wind direction and staying indoors on high-pollution days is advisable.
