Palembang, strategically positioned along the Musi River in southeastern Sumatra, Indonesia, serves as a major urban hub and provincial capital of South Sumatra. Its equatorial lowland geography, with an average elevation of just 8 meters above sea level, profoundly influences its air quality dynamics. The city sprawls across both banks of the broad, slow-moving Musi River, creating a distinctive urban character where water transport and riverside settlements are integral. Surrounding Palembang lies a mosaic of tropical peatlands, oil palm plantations, and mixed agricultural zones, particularly to the west and south, which contribute to regional haze during dry periods. To the east, the city transitions into more densely populated urban and industrial areas, including the nearby industrial belt of Jakabaring and its manufacturing zones. This low-lying terrain, combined with proximity to the river and extensive wetlands, often traps pollutants under stable atmospheric conditions, exacerbating local emissions from transportation, residential burning, and general urban activities. The urban–rural gradient sees decreasing pollution levels toward the less developed northern and western fringes, but prevailing winds from the southeast can carry agricultural and peatland emissions into the city. Palembang's location in a river basin, flanked by modest hills to the distant west, creates a natural amphitheater effect that occasionally hinders pollutant dispersion, making geographic context a key factor in its air quality challenges.

Palembang's air quality follows a seasonal rhythm shaped by its equatorial monsoon climate, with distinct wet and dry periods rather than four traditional seasons. From November to March, the northwest monsoon brings heavy rainfall, which effectively scrubs pollutants from the air, resulting in the cleanest conditions and making this period ideal for outdoor activities. Sensitive groups, such as those with respiratory issues, should still monitor daily forecasts but can generally breathe easier during these months. As the dry season emerges from April to October, pollution levels gradually rise, peaking around June to September when rainfall diminishes and southeast winds prevail. During these months, temperature inversions are common in the early mornings, trapping emissions from vehicles, industrial processes, and occasional agricultural burning in the surrounding regions. Haze from peatland fires in South Sumatra can also drift into Palembang, particularly in late dry season months, creating episodic spikes in pollution. Fog is rare, but reduced visibility may occur due to particulate matter. For health guidance, vulnerable individuals should limit prolonged outdoor exertion during the dry season, especially in peak pollution months, and use air purifiers indoors. Planning visits or outdoor events in the wetter months can minimize exposure to poor air quality.
