Baclaran, a densely populated barangay within Parañaque City, Philippines, occupies a strategically significant coastal location at 14.5319° N, 120.9942° E. Situated on the western shore of Manila Bay, its geography is characterized by a relatively flat terrain, averaging only a few meters above sea level, making it highly susceptible to coastal flooding and storm surges. The surrounding landscape is a complex mix of urban development, informal settlements, and remnants of mangrove forests along the bay’s edge. Baclaran’s position within the sprawling Metro Manila conurbation places it within a major urban corridor, experiencing intense human activity and associated pollution sources. To the east lies the sprawling urban fabric of Metro Manila, including industrial zones and commercial hubs, while the Manila Bay to the west introduces a maritime influence. The urban–rural gradient is abrupt; Baclaran transitions almost immediately from high-density residential areas to more industrial and commercial zones. The proximity to Manila Bay, while offering some cooling breezes, also contributes to the trapping of pollutants, particularly during periods of low wind speed. Agricultural zones are largely absent in the immediate vicinity, with most food sources imported from outside the region. The bay itself, once a thriving ecosystem, now suffers from significant pollution, impacting air quality through the release of volatile organic compounds and particulate matter. The area’s low elevation and coastal location exacerbate the impacts of climate change, potentially leading to increased flooding and further degradation of air quality due to saltwater intrusion and associated microbial processes.

Baclaran’s tropical climate dictates a wet and dry season pattern, profoundly influencing its air quality. The wet season, typically spanning from June to November, brings monsoon rains and increased humidity. While rainfall can temporarily cleanse the air by washing away particulate matter, the associated increased vehicle traffic due to flooding and the prevalence of damp conditions can contribute to mold and fungal spore concentrations, impacting respiratory health. The dry season, from December to May, often sees a build-up of pollutants. Temperature inversions, common during the cooler months (December-February), trap emissions close to the ground, leading to stagnant air and elevated concentrations of pollutants. The prevailing winds during this period are often light, further hindering dispersion. March and April, characterized by rising temperatures and increased construction activity, frequently experience elevated levels of dust and construction-related particulate matter. The maritime influence of Manila Bay can also contribute to fog formation, particularly during the cooler months, which further restricts air movement and traps pollutants. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during periods of stagnant air, especially during the dry season and when fog is present. Outdoor activities are generally more favourable during the wetter months, although vigilance regarding flood-related hazards is essential. The transition months (May and November) often present unpredictable air quality conditions, requiring careful monitoring and adaptive behaviour.
