Maungdaw is a coastal town in Myanmar's Rakhine State, situated on the eastern bank of the Naf River estuary where it meets the Bay of Bengal. This strategic location at approximately 20.8°N latitude places it within Southeast Asia's monsoon belt, with terrain characterized by low-lying coastal plains rarely exceeding 10 meters in elevation. The urban area blends with surrounding rural landscapes dominated by rice paddies and fishing communities, creating a distinct urban-rural gradient where agricultural burning contributes to regional haze. Proximity to the Bay of Bengal influences local meteorology, with sea breezes typically dispersing pollutants but occasionally trapping them when atmospheric conditions stagnate. The town serves as a regional administrative and commercial hub, with pollution sources primarily stemming from general urban activities—vehicle emissions from aging fleets, residential biomass burning for cooking, and occasional dust from unpaved roads. Its position near the Bangladesh border adds transboundary pollution influences, particularly during dry seasons when winds carry agricultural residues and industrial emissions across the Naf River. The flat coastal topography offers little natural barrier to pollutant dispersion, though the river estuary creates microclimates where fog and humidity can exacerbate particulate matter accumulation. This geography creates a complex air quality scenario where local emissions interact with regional agricultural patterns and maritime influences.

Maungdaw's air quality follows distinct seasonal patterns driven by the monsoon cycle. During the dry season from November to April, particularly in February and March, pollution typically peaks due to stagnant atmospheric conditions, reduced rainfall, and increased agricultural burning in surrounding areas. These months experience temperature inversions that trap pollutants near the ground, making them the least favorable for outdoor activities, especially for sensitive groups like children, elderly residents, and those with respiratory conditions. The southwest monsoon from May to October brings cleansing rains that significantly improve air quality, with June through August offering the cleanest air as frequent precipitation washes pollutants from the atmosphere. However, the monsoon transition months of April-May and October-November can see variable conditions with occasional haze from pre-monsoon agricultural fires or post-monsoon dust resuspension. Fog occasionally develops in December-January, combining with pollutants to create visibility issues and health concerns. Sensitive individuals should monitor local conditions during peak pollution months, limit strenuous outdoor activities when haze is visible, and consider indoor air filtration during prolonged dry spells. The maritime influence moderates extreme pollution episodes compared to inland cities, but vulnerable populations should remain cautious during seasonal transitions when wind patterns shift unpredictably.
