Qaraçuxur, a district within Baku, Azerbaijan, occupies a unique geographic position on the Absheron Peninsula, bordering the Caspian Sea. Situated at coordinates 40.3969° N, 49.9733° E, the city’s terrain is largely flat, characteristic of the peninsula’s sedimentary landscape. This low-lying coastal plain is subject to sea breezes and experiences a semi-arid climate. The surrounding landscape transitions from urban development to agricultural lands further inland, particularly towards the west, and is punctuated by oil fields and industrial zones associated with Baku’s petroleum industry. Qaraçuxur’s proximity to the Caspian Sea influences local weather patterns, moderating temperatures but also contributing to humidity and potential for fog. The urban-rural gradient is relatively sharp, with dense residential areas giving way quickly to agricultural fields and then to the more expansive oil infrastructure. This proximity to both industrial activity and a large body of water creates a complex interplay of factors impacting air quality. The prevailing winds, often from the north and northwest, can carry pollutants from industrial sources across the city and out over the Caspian, while localized emissions from traffic and residential heating contribute to concentrated pollution pockets. The flat terrain also limits natural dispersion of pollutants, exacerbating air quality issues during calm weather conditions.

Qaraçuxur’s air quality follows a distinct seasonal pattern. Spring (March-May) sees a gradual improvement after the winter months, though dust storms originating from the surrounding arid regions can temporarily elevate particulate matter. Summer (June-August) generally offers the cleanest air, benefiting from sea breezes that help disperse pollutants, but high temperatures can promote ozone formation. However, increased recreational activity along the coast can lead to localised emissions. Autumn (September-November) marks a deterioration in air quality as temperatures drop and heating systems are activated. This period often experiences temperature inversions, trapping pollutants near the ground. November is typically the most polluted month due to increased coal and gas burning for heating. Winter (December-February) consistently presents the poorest air quality. Calm conditions, frequent temperature inversions, and heavy reliance on fossil fuels for heating combine to create stagnant air and high concentrations of pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor exposure during autumn and winter. Monitoring wind direction is crucial; winds from industrial areas will carry higher pollution levels. Avoiding peak traffic hours and exercising indoors during periods of poor visibility are also recommended.
