Zaouiet Sousse, a municipality within the Sousse Governorate of Tunisia, occupies a crucial position along the nation’s central Mediterranean coastline. Situated at approximately 35.7833°N, 10.6333°E, the city benefits from a relatively flat coastal plain, gently rising inland. This terrain, characteristic of much of the Sahel region, facilitates agricultural activity, with olive groves and market gardens dominating the surrounding landscape. The proximity to the Mediterranean Sea exerts a moderating influence on the climate, but also introduces sea breezes that can trap pollutants under certain atmospheric conditions. While Zaouiet Sousse isn’t a major industrial hub like Sousse city itself, it serves as a vital agricultural processing and distribution centre, contributing to localised emissions from transport and small-scale industries. The urban-rural gradient is relatively sharp, transitioning quickly from residential areas to agricultural fields. Dust from these fields, particularly during drier periods, is a significant contributor to particulate matter. The city’s location within a wider coastal corridor means it’s susceptible to regional pollution transport from larger urban centres and industrial zones further along the Tunisian coastline. Understanding these geographical factors is key to addressing air quality challenges in Zaouiet Sousse.

Zaouiet Sousse experiences a Mediterranean climate, with distinct seasonal variations impacting air quality. Summer (June-August) often sees relatively good air quality due to prevailing northerly winds dispersing pollutants, though high temperatures can exacerbate ozone formation. However, increased tourist activity and associated vehicle traffic can locally elevate nitrogen dioxide levels. Autumn (September-November) brings a transition period, with decreasing temperatures and potentially stagnant air masses leading to a build-up of particulate matter from agricultural activities and domestic heating. Winter (December-February) is typically the period of poorest air quality. Reduced sunlight and temperature inversions trap pollutants close to the ground, compounded by increased use of wood and charcoal for heating. Sensitive individuals, particularly those with respiratory conditions, should limit outdoor exposure during these months. Spring (March-May) sees improving conditions as temperatures rise and winds become more frequent, flushing out accumulated pollutants. However, dust storms originating from the Sahara Desert can periodically impact air quality. Months to favour for outdoor activity are June-August, but even then, monitoring local conditions is advisable. Individuals with asthma or heart conditions should be particularly cautious during winter and periods of high dust concentration.
