Araklı, nestled along the Black Sea coast in Trabzon, Turkey, occupies a dramatic and challenging geographic position. Situated at approximately 40.9333° latitude and 40.0500° longitude, the city’s defining feature is its steep, terraced landscape, carved over centuries by fluvial processes and human intervention. The terrain rises sharply from the Black Sea, creating a series of plateaus and valleys, typical of the mountainous Black Sea Region. This topography significantly influences air circulation patterns; cool, moist air from the Black Sea frequently flows inland, often becoming trapped within the valleys, particularly during periods of calm weather. The surrounding landscape is dominated by dense forests of spruce, fir, and beech, interspersed with agricultural land – primarily tea plantations and hazelnut orchards, vital to the local economy. Araklı’s proximity to the Black Sea moderates temperatures but also introduces maritime influences, including higher humidity and potential for sea spray. While Araklı isn't directly adjacent to major industrial belts, it lies within a region experiencing increasing urbanization and agricultural intensification. The urban–rural gradient is relatively sharp, with the city transitioning quickly to agricultural land and forested slopes. This interplay of steep terrain, maritime climate, and agricultural activity creates a unique microclimate that can exacerbate localized air quality issues, particularly concerning particulate matter and volatile organic compounds (VOCs) from agricultural practices and residential heating.

Araklı’s air quality follows a distinct seasonal pattern dictated by its Black Sea climate. Winters (December-February) are characterized by high humidity, frequent rainfall, and periods of prolonged fog, often leading to stagnant air conditions and increased concentrations of pollutants. Temperature inversions, common during these months, trap cold air near the ground, further hindering dispersion. Agricultural burning, a traditional practice for land clearing and residue disposal, can significantly contribute to particulate matter pollution during this period. Spring (March-May) brings a gradual improvement as winds increase and temperatures rise, dispersing pollutants more effectively. However, pollen levels rise sharply, impacting those with respiratory sensitivities. Summer (June-August) generally sees the best air quality, with consistent winds and higher temperatures promoting good ventilation. However, occasional heatwaves can lead to increased ozone formation. Autumn (September-November) presents a transitional period. The harvest season for tea and hazelnuts intensifies agricultural activity, potentially releasing dust and VOCs. Rainfall increases, helping to cleanse the air, but periods of calm weather can still lead to localized pollution episodes. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during winter months, limiting outdoor activity on foggy days and avoiding areas near agricultural burning. During pollen season, those with allergies should take appropriate preventative measures. Maintaining indoor air quality through ventilation and air purification can also be beneficial throughout the year.
