Thick haze originating from widespread wildfires in Indonesia has drifted across the sea, blanketing parts of the Philippines and prompting urgent health warnings. Authorities in several regions, including Quezon City, have suspended classes as air quality sensors registered levels ranging from “unhealthy” to “acutely unhealthy.” Environmental officials attribute the poor air quality to trans-boundary smoke carried by prevailing winds, which has significantly impacted at least 10 cities. Residents, particularly those at higher risk, have been advised to limit outdoor activities and wear protective masks to mitigate the health hazards posed by the fine particulate matter.

The crisis stems from a brutal wildfire season exacerbated by "super-El Niño" weather conditions, which have fueled blazes across five of Indonesia’s major islands. Experts note that these fires are often tied to slash-and-burn agricultural practices, a problem historically linked to remote land development and poverty. To manage the ongoing threat, health professionals urge the public to remain indoors, keep windows sealed, and use N95 or KN95 masks if travel is necessary. Staying hydrated is also highly recommended to help alleviate the respiratory irritation caused by the lingering smoke.
