Candijay, Bohol, nestled on the eastern coast of the island, presents a unique geographic profile significantly influencing its air quality. Situated at approximately 9.8180° N, 124.4960° E, the municipality occupies a coastal plain transitioning into gently rolling hills and eventually, the rugged interior highlands of Bohol. Its location along the coast of the Philippine Sea exposes it to prevailing easterly trade winds, a crucial factor in air dispersal. The surrounding landscape is dominated by lush tropical rainforest, interspersed with agricultural lands primarily dedicated to coconut and rice cultivation. This rural-urban gradient is relatively smooth, with Candijay exhibiting a predominantly rural character despite its designation as a municipality. The Can-umantad River, a significant waterway, flows through the area, contributing to the region's humidity and influencing local weather patterns. Elevation varies from near sea level along the coast to several hundred meters inland, creating localized microclimates. While Bohol lacks major industrial belts, the presence of small-scale agricultural processing facilities and limited vehicular traffic contribute to localized pollution sources. The terrain, with its hills and valleys, can trap pollutants under certain meteorological conditions, particularly during periods of reduced wind activity. The proximity to the Philippine Sea also means the potential for saltwater aerosols to influence air composition, though this is generally less impactful than terrestrial sources.

Candijay’s tropical climate dictates a wet and dry season, profoundly impacting air quality dynamics. The dry season, typically spanning from March to May, often sees a slight increase in particulate matter due to agricultural burning practices, a common method for clearing land and managing crop residue. While not widespread, these localized burns can temporarily degrade air quality, particularly in areas closer to agricultural zones. The wet season, from June to November, brings frequent rainfall and increased humidity, generally leading to improved air quality as precipitation washes away pollutants and higher humidity traps particulate matter. During the monsoon months (July-September), strong easterly winds prevail, effectively dispersing any accumulated pollutants and maintaining relatively clean air. Fog, though infrequent, can occasionally form in the higher elevations inland, trapping pollutants and creating localized pockets of reduced visibility and potentially poorer air quality. Temperature inversions, where cooler air settles below warmer air, are rare but possible during the cooler months (December-February), potentially trapping pollutants near the ground. Sensitive groups, such as children, the elderly, and individuals with respiratory conditions, should be mindful of agricultural burning during the dry season and exercise caution during periods of fog or potential temperature inversions. Outdoor activities are generally favoured during the wet season and the cooler months, with the strongest winds providing the best air dispersal.
