Mudanya, a district of Bursa, Turkey, occupies a strategically significant position on the southern coast of the Sea of Marmara, approximately 16 kilometers west of Bursa city center. Its geography is a compelling blend of coastal plains, gently sloping hills, and the foothills of the Uludağ mountain range looming to the south. The city’s terrain is predominantly undulating, transitioning from flat coastal areas to moderately steep slopes as one moves inland. This varied topography significantly influences local air circulation patterns. Mudanya’s location at the mouth of the Mudanya River, combined with its exposure to the Sea of Marmara, creates a maritime climate, moderating temperature extremes. The surrounding landscape is a patchwork of olive groves, vineyards, and small-scale agriculture, characteristic of the broader Bursa region. To the east lies the industrial belt of Bursa, a significant contributor to regional air quality challenges, while to the west, the urban–rural gradient gradually shifts towards more agricultural land. The proximity to the Sea of Marmara can, at times, trap pollutants, particularly during periods of calm weather. Elevation varies from sea level along the coast to several hundred meters inland, impacting the dispersion of airborne particles. The city’s coastal location also means it is susceptible to sea salt aerosol deposition, which can exacerbate respiratory issues for some individuals. The prevailing winds generally blow from the northwest, influencing the transport of pollutants from Bursa and surrounding areas.

Mudanya’s air quality experiences a distinct seasonal cycle driven by meteorological factors. Winters, spanning roughly November to March, often bring the most challenging conditions. Temperature inversions, common during this period, trap pollutants close to the ground, leading to increased concentrations of particulate matter and other emissions from Bursa’s industrial zone. Fog, frequently occurring in December and January, further restricts dispersion. Spring (April-May) sees a gradual improvement as winds increase and temperatures rise, dispersing pollutants more effectively. However, agricultural burning practices in the surrounding rural areas can occasionally contribute to localized spikes in smoke and particulate matter. Summers (June-August) generally offer the best air quality, with consistent winds and high temperatures promoting efficient pollutant dispersal. The sea breeze plays a crucial role in ventilating the city. Autumn (September-October) marks a transitional period, with decreasing wind speeds and the potential for temperature inversions to re-emerge, though typically less severe than in winter. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter months, limiting outdoor activity on days with stagnant air. Springtime agricultural burning warrants awareness, and monitoring local air quality reports is advisable. While summer generally provides cleaner air, heatwaves can still impact air quality due to ozone formation. Overall, Mudanya’s air quality is most vulnerable during the colder, calmer months.
