Selimpaşa occupies a strategic coastal position within the Silivri district of Istanbul, serving as a transitional zone between the dense urban sprawl of the metropolis and the expansive agricultural plains of Thrace. Situated along the shores of the Sea of Marmara, its geography is characterized by a predominantly flat coastal terrain with gentle undulations that slope toward the shoreline. This low-lying topography allows the maritime influence to penetrate inland, creating a unique urban character that blends residential summer villas with permanent agricultural settlements. However, this same geography plays a critical role in the region's air quality dynamics. The proximity to the sea typically ensures a refreshing breeze that helps disperse pollutants; yet, Selimpaşa sits precariously near several industrial belts and greenhouse clusters. The urban-rural gradient is stark, where residential pockets are interspersed with intensive farming zones. During periods of atmospheric stability, pollutants from nearby industrial facilities and agricultural emissions can linger, as the flat terrain offers few natural barriers to block the drift of particulate matter from the hinterland. The elevation remains low, meaning the area is susceptible to the overarching regional weather patterns of the Marmara basin. Consequently, the air quality is a constant tug-of-war between the cleansing effects of the sea breeze and the anthropogenic emissions from the burgeoning industrial periphery of Western Istanbul, making its atmospheric health deeply dependent on wind direction.

Air quality in Selimpaşa fluctuates through a distinct seasonal cycle driven by the Mediterranean climate and maritime currents. In winter, the region often experiences temperature inversions, where cold air traps pollutants near the ground, exacerbated by the increased use of solid fuels for domestic heating. This period marks the peak for particulate matter, making January and February challenging for those with respiratory sensitivities. As spring arrives, shifting wind patterns and increased rainfall typically scrub the atmosphere, leading to a noticeable improvement in clarity and air purity. This is the ideal window for outdoor activities. Summer brings the dominance of the sea breeze, which generally flushes the coastline with fresh air; however, high temperatures can trigger the formation of ground-level ozone, particularly during stagnant heatwaves in July and August. Autumn serves as a transitional phase where the air is often crisp, though the seasonal burning of agricultural residues in the surrounding Thrace plains can lead to temporary spikes in smoke and haze during October. For sensitive groups, including children and the elderly, the winter months necessitate caution and the limitation of prolonged outdoor exertion during stagnant mornings. Conversely, the late spring and early autumn months offer the most favorable conditions. Monitoring wind direction is essential, as northeasterly winds typically bring cleaner air from the Black Sea, while southerly winds may carry industrial emissions from the denser urban corridors of Istanbul.
