Sidi Azzouz, a commune within the Marrakech-Safi region of Morocco, is situated approximately 15km northeast of Marrakech city centre, at coordinates 31.7600°N, -7.6600°W. The town occupies a relatively flat section of the Haouz Plain, a vast expanse historically used for agriculture, now experiencing increasing urban sprawl. Its elevation of around 480 meters above sea level contributes to a Mediterranean climate with continental influences. The High Atlas Mountains loom large to the south, acting as a significant orographic barrier, influencing wind patterns and precipitation. While not directly adjacent to a major body of water, the proximity to the Draa River valley, further south, impacts regional humidity. Sidi Azzouz is experiencing a rapid urban-rural gradient as Marrakech’s expansion encroaches upon surrounding agricultural land. This transition is accompanied by increased traffic and construction, contributing to localised dust and particulate matter. The surrounding landscape is dominated by olive groves and cereal farms, with some small-scale industrial activity concentrated closer to Marrakech. The plain’s limited natural ventilation, coupled with the mountain barrier, can trap pollutants, particularly during temperature inversions. The town’s location within this dynamic landscape presents unique challenges for maintaining air quality as it grows.

Air quality in Sidi Azzouz follows a distinct seasonal pattern. Spring (March-May) sees a gradual improvement after the winter, though dust storms originating from the Sahara Desert are common, particularly in March and April, elevating particulate matter levels. Summer (June-August) is typically the period of best air quality, with prevailing winds helping to disperse pollutants, and minimal heating demands reducing emissions from residential sources. However, intense heat can exacerbate ozone formation. Autumn (September-November) marks a transition, with decreasing wind speeds and the onset of temperature inversions, trapping pollutants closer to the ground. This period often sees a rise in particulate matter from agricultural burning as farmers clear fields after harvest. Winter (December-February) is generally the worst period for air quality. Cold temperatures lead to increased use of wood and charcoal for heating, releasing significant amounts of smoke and particulate matter. Temperature inversions are frequent, exacerbating the problem. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during autumn and winter months. Monitoring wind direction and avoiding peak heating hours can help mitigate exposure. The dry climate generally limits fog formation, but localised humidity can contribute to pollutant concentration.
