Cagwait, a municipality in the province of Surigao del Sur, Philippines, is a coastal town nestled along the Pacific Ocean. Its coordinates (8.9181, 126.3017) place it within a region characterized by a rugged, mountainous interior descending towards a narrow coastal plain. The terrain is predominantly undulating, with hills and small mountains influencing local wind patterns. The town’s elevation is relatively low, contributing to humidity and potentially trapping pollutants. Cagwait’s urban character is largely defined by its coastal location; fishing is a primary industry, and the town centre is concentrated near the shoreline. Surrounding Cagwait are extensive areas of coconut plantations and agricultural land, typical of the Surigao del Sur landscape. While not heavily industrialized, the region experiences some mining activity further inland, which can contribute to particulate matter transport. The urban-rural gradient is quite sharp, with quickly transitioning landscapes from populated areas to dense vegetation. This proximity to both the ocean and agricultural zones significantly impacts air quality, with sea breezes offering some dispersion, but agricultural burning potentially increasing particulate matter, especially during dry periods. The prevailing winds, influenced by the Pacific trade winds, play a crucial role in pollutant dispersal, but local topography can create pockets of stagnant air.

Cagwait experiences a distinct wet and dry season, rather than traditional four seasons. Air quality is generally better during the wet season (roughly November to May) due to frequent rainfall which effectively washes particulate matter from the atmosphere. However, increased humidity can also promote the formation of mold and allergens. The peak of the dry season (June to October) typically sees a decline in air quality. This is largely due to increased agricultural activities, including slash-and-burn farming practices to clear land for planting, releasing significant amounts of smoke and particulate matter. Wind patterns during this period can be less consistent, leading to localized pollution build-up. Temperature inversions, though less common than in larger urban centres, can occur, trapping pollutants near the ground. November and December, marking the transition to the wet season, often experience intermittent rainfall and fluctuating air quality. For those with respiratory sensitivities, avoiding outdoor exertion during peak dry season months (August-September) is advisable. Monitoring local weather patterns and being aware of agricultural burning is crucial. The northeast monsoon, bringing heavier rainfall, generally improves conditions from December onwards. Sensitive groups, including children and the elderly, should take precautions during periods of increased agricultural activity.
