Métouia sits in the heart of the Gabès Governorate, positioned within the low-lying coastal plains of southeastern Tunisia. Its geography is defined by its proximity to the Gulf of Gabès, which introduces a significant maritime influence to the local microclimate. The terrain is predominantly flat, characterized by a transition from the semi-arid interior landscapes to the more fertile, albeit increasingly industrial, coastal strip. This location places Métouia in a critical transition zone where the urban character of the Gabès industrial belt meets traditional agricultural patterns. The city’s position is heavily influenced by the nearby chemical and phosphate processing industries that dominate the regional economy. These industrial clusters, situated along the coast, create a complex urban-rural gradient where atmospheric dispersion is shaped by both sea breezes and land winds. The low elevation means that pollutants can become trapped near the surface, especially when meteorological conditions favor stagnation. Furthermore, the surrounding landscape, characterized by sparse vegetation and salt-tolerant flora, offers limited natural filtration for airborne particulates. The interplay between the Mediterranean Sea and the arid hinterland creates a dynamic environment where wind patterns significantly dictate the movement of emissions from the heavy industrial zones toward residential areas like Métouia. Consequently, the local air quality is inextricably linked to both industrial output and regional meteorological shifts, as the coastal interface regulates the dispersal of chemical aerosols and fine dust particles across the township, creating a unique atmospheric profile that fluctuates with the seasonal rhythms of the North African coast and its shifting winds.

In Métouia, the air quality narrative is dictated by the harsh Mediterranean climate and the proximity of heavy industrial processes. Summer months, particularly July and August, often present the most challenging conditions due to the arrival of the Sirocco—a hot, dry wind from the Sahara. This wind carries significant amounts of fine mineral dust and can exacerbate the concentration of industrial pollutants by preventing vertical mixing. Conversely, during the winter months, the region can experience temperature inversions, where a layer of warm air traps cooler, more polluted air near the ground, particularly during the still, foggy mornings of December and January. These periods of stagnation can lead to noticeable increases in particulate matter. Spring and autumn typically offer the most favorable conditions for outdoor activities, as moderate temperatures and more consistent sea breezes help to cleanse the atmosphere and disperse industrial emissions effectively. For sensitive groups, including children, the elderly, and those with respiratory conditions like asthma, it is advisable to monitor wind shifts and avoid prolonged outdoor exertion during peak Sirocco events or during heavy winter inversion periods. During these times, keeping windows closed and using air filtration can mitigate exposure. As the seasonal rhythm shifts from the dry, dusty heat of summer to the milder, more ventilated transitional months, the community must remain vigilant of the changing meteorological patterns that define the local atmospheric health, ensuring that residents can adapt to the complex air quality dynamics inherent to this unique coastal and industrial intersection in the Gabès region.
