Şarköy, nestled along the Marmara Sea coast in Tekirdağ Province, Turkey, occupies a geographically significant position within the Thracian region. Its coordinates (40.6039, 27.1064) place it within a gently sloping coastal plain, transitioning to rolling hills inland. The city’s defining feature is its proximity to the Marmara Sea, a major waterway connecting the Black Sea and the Aegean Sea, influencing local weather patterns and, crucially, air quality. Şarköy’s terrain is characterized by vineyards and olive groves, reflecting the region’s agricultural heritage. The surrounding landscape is a mosaic of cultivated fields, small villages, and patches of Mediterranean scrubland, creating a gradual urban-rural gradient. While Şarköy itself is a relatively small town, it benefits from its location within the broader Istanbul-Kocaeli industrial belt, approximately 150 kilometers west. This proximity, while offering economic opportunities, introduces a potential source of long-range air pollution transport. The elevation is relatively low, averaging around 50 meters above sea level, which can exacerbate the trapping of pollutants during temperature inversions. The prevailing winds generally blow from the northwest, carrying maritime air inland, but this can shift seasonally. The town’s coastal location also means it is susceptible to sea breezes, which can both disperse and concentrate pollutants depending on atmospheric stability. The agricultural zones surrounding Şarköy contribute to localized emissions, particularly during planting and harvesting seasons, impacting the air quality with dust and agricultural chemicals.

Şarköy’s air quality experiences a distinct seasonal cycle heavily influenced by meteorological conditions. Summer (June-August) typically sees the clearest air, driven by consistent sea breezes that effectively disperse pollutants. These winds, coupled with higher temperatures, promote good ventilation. However, prolonged periods of intense heat can lead to stagnant air conditions, particularly in sheltered areas, potentially increasing ground-level ozone. Autumn (September-November) marks a transition period. As temperatures cool, the frequency of temperature inversions increases, trapping pollutants closer to the ground, especially during calmer days. Agricultural activities intensify during this period, contributing to particulate matter from field operations. Winter (December-February) often brings the poorest air quality. Cold, stable air masses, coupled with frequent fog and temperature inversions, lead to pollutant accumulation. The lack of strong winds further exacerbates this issue. While snowfall can temporarily cleanse the air, the subsequent melting can release trapped pollutants. Spring (March-May) witnesses a gradual improvement as temperatures rise and winds increase, though dust storms originating from the Anatolian plateau can occasionally impact air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter months and be mindful of potential ozone spikes during summer heatwaves. Outdoor activities are generally best enjoyed during the spring and summer, avoiding periods of stagnant air or high pollen counts.
