Poti is a vital maritime gateway situated within the Colchis Lowland of western Georgia, characterized by its exceptionally low-lying, alluvial terrain. Positioned at the mouth of the Rioni River where it meets the Black Sea, the city serves as a critical nexus for regional trade and logistics. The urban character is defined by its role as a major port, where the intersection of riverine and maritime environments creates a complex microclimate. The elevation is minimal, making the city highly susceptible to the moisture-laden winds blowing off the Black Sea. This proximity to a vast body of water acts as a natural thermal regulator, yet it also introduces significant humidity that can trap airborne particulates. The surrounding landscape is a mosaic of wetland ecosystems, fertile agricultural zones, and industrial maritime infrastructure. As a primary transit hub, Poti experiences a distinct urban-rural gradient where the concentrated emissions from shipping vessels, heavy-duty port machinery, and logistics corridors meet the more dispersed agricultural activities of the Samegrelo-Zemo Svaneti region. The convergence of the Rioni’s discharge and the sea’s ebb and flow influences local wind patterns, which play a decisive role in the dispersion or stagnation of pollutants. Consequently, the air quality in Poti is deeply intertwined with its hydrologic and industrial profile, as the heavy, humid air often facilitates the suspension of aerosols near the ground level, particularly within the dense port zones. This dynamic creates a unique atmospheric condition where maritime influences and industrial output always negotiate for the city's breathable air space.

Poti’s air quality follows a distinct seasonal rhythm dictated by its humid subtropical climate and maritime proximity. During the spring months, from March to May, the atmosphere often experiences moderate stability. While the winds can be refreshing, occasional temperature inversions can trap moisture and particulates near the surface, especially during early morning hours. Summer brings intense heat and high humidity, which, when coupled with heavy port activity, can exacerbate the concentration of aerosols. However, the strong sea breezes typical of July and August often act as a cleansing mechanism, facilitating the dispersion of maritime and industrial emissions. Autumn, particularly September and October, marks a transitional period where increasing cloud cover and frequent rainfall help to wash pollutants from the air, leading to periods of high clarity. Winter presents the most complex challenges; from December to February, the combination of lower temperatures, frequent fog, and reduced wind speeds can lead to atmospheric stagnation. During these months, pollutants from shipping and local transport may linger longer in the heavy, damp air. For sensitive groups, such as those with respiratory conditions, the foggy winter mornings and the humid, heavy heat of late summer are periods to exercise caution. Generally, the most favorable times for vigorous outdoor activities are the breezy summer afternoons and the crisp, rain-washed days of autumn, when the maritime winds most effectively clear the urban atmosphere. This ensures that residents can plan their lifestyles around the natural cycles of the Black Sea and the Rioni River for optimal health outcomes.
