Talisay City occupies a strategic position in Central Visayas, Philippines, nestled along the eastern coast of Cebu Island with coordinates at 10.2500°N, 123.8300°E. This urban center sits approximately 10 kilometers south of Cebu City, forming part of the bustling Metro Cebu conurbation that stretches along the island's eastern shoreline. The city's geography is characterized by a coastal plain that gently rises toward the central mountain range of Cebu Island, creating an elevation gradient from sea level to approximately 100 meters in its western reaches. This terrain significantly influences air quality patterns, as the mountains to the west can trap pollutants during periods of light winds, particularly when temperature inversions occur. Talisay's immediate proximity to the Tanon Strait provides some natural ventilation, with sea breezes typically helping to disperse urban emissions during daytime hours. The city exists within a distinct urban-rural transition zone, where densely populated barangays near the coast gradually give way to more agricultural areas toward the interior, though rapid urbanization has blurred these boundaries in recent decades. Industrial activity in Talisay is moderate compared to northern Metro Cebu areas, with light manufacturing, food processing, and service sectors predominating, though vehicle emissions from the national highway traversing the city contribute substantially to local pollution. The surrounding landscape includes both marine and terrestrial elements, with mangrove areas along the coast and agricultural plots growing corn, vegetables, and fruit trees in upland areas, though these are increasingly giving way to residential development. This geographic context creates a complex air quality environment where coastal influences, urban expansion, and topographic features interact to determine pollution dispersion patterns throughout the year.

Talisay experiences a tropical climate with two primary seasons that shape its air quality narrative throughout the year. During the dry season from January to May, typically the period of poorest air quality, reduced rainfall allows pollutants to accumulate, particularly from February through April when winds are often lightest. These months frequently see temperature inversions developing overnight and into early morning, trapping vehicle emissions and particulate matter near ground level, creating hazy conditions that are most pronounced in the city's western sections where topography restricts dispersion. Sensitive groups including children, elderly residents, and those with respiratory conditions should limit strenuous outdoor activities during late mornings when pollution concentrations often peak. The wet season from June to December brings relief through the southwest monsoon (habagat) from June to September and northeast monsoon (amihan) from October to December, with frequent rains effectively scrubbing the atmosphere of pollutants. August through October typically offers the cleanest air as monsoon winds and precipitation maximize dispersion and removal mechanisms. However, brief periods of reduced air quality can occur during transitional months when wind patterns shift, particularly in November as the habagat gives way to the amihan. Fog is uncommon in Talisay's coastal location, though haze from regional agricultural burning occasionally affects visibility during March and April. The city's proximity to the sea moderates temperature extremes year-round, but the combination of high humidity and pollution during dry months can exacerbate respiratory discomfort. For optimal outdoor activity timing, early mornings before traffic peaks or late afternoons after sea breezes establish offer better conditions during problematic months, while the rainy season generally provides consistently good air quality aside from immediately following heavy downpours when road dust may be temporarily resuspended.
