Brookes Point, nestled on the western coast of Palawan Island in the Philippines, occupies a geographically significant position. Situated at 8.7800°N, 117.8300°E, the municipality’s terrain is characterized by a blend of coastal plains, rolling hills, and mountainous interiors, rising to elevations that influence local wind patterns. The town directly borders the South China Sea, experiencing the full impact of maritime weather systems. Unlike heavily industrialized urban centers, Brookes Point’s air quality is less impacted by large-scale industrial emissions. However, its proximity to extensive agricultural lands – primarily rice paddies and coconut plantations – introduces seasonal biomass burning as a potential source of particulate matter. The urban-rural gradient is pronounced; the town center is relatively compact, transitioning quickly to rural landscapes dominated by agriculture and forests. This creates localized variations in air quality, with potential for higher concentrations of pollutants near agricultural activities. The surrounding landscape, rich in biodiversity, also contributes to natural aerosols, like pollen and sea salt, impacting air composition. The prevailing winds, influenced by the monsoon seasons and the island’s topography, play a crucial role in dispersing or concentrating pollutants. Understanding this interplay is vital for assessing and managing air quality in Brookes Point.

Brookes Point experiences a distinct wet and dry season, heavily influencing air quality. The dry season, typically from December to May, sees lower rainfall and stronger winds, which can initially disperse pollutants. However, this period also coincides with increased agricultural activity, including land preparation through slash-and-burn practices, leading to spikes in particulate matter (PM2.5 and PM10). February and March are often the months with the highest potential for smoke haze. The onset of the wet season, around June, brings relief as rainfall effectively washes pollutants from the atmosphere. Air quality generally improves significantly during the peak of the wet season (August-October). However, increased humidity can also foster mold growth, potentially impacting indoor air quality. November marks a transitional period, with decreasing rainfall and a gradual return to drier conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should exercise caution during the dry season, limiting strenuous outdoor activity on days with visible haze. Monitoring wind direction is crucial; onshore winds will carry pollutants from burning activities directly into the town. Overall, the wet season offers the most favourable conditions for outdoor activities, while the dry season requires increased vigilance.
