Haze From Indonesia Fires Reaches Davao, Prompting a Health Advisory
Smoke drifting north from land fires in Kalimantan, Indonesia settled over parts of Mindanao in early September, pushing air quality in Davao City into the range that health officials call unhealthy for sensitive groups. Environmental and health agencies in the Davao Region told children, older residents, and people with breathing problems to limit time outdoors. Readings elsewhere in the region stayed within safer bands, and forecasters said rain and shifting winds could clear the haze within days.
Quick Answer
Sensitive residents should check current EMB readings before prolonged outdoor activity and use a fitted mask when particle levels worsen.
What the advisory says
The Environmental Management Bureau in the Davao Region reported thicker than usual haze over Davao City around the start of September, with an air monitoring station in Calinan recording fine particle levels in the unhealthy for sensitive groups band. The bureau advised children, senior citizens, and people with respiratory conditions to limit prolonged time outdoors when readings reach that level, and said the general public could carry on with normal activity while the air stays fair.
Health officials in the region added practical steps: keep windows closed when haze is heavy, wear a well fitting mask outdoors, and watch for official updates. They also flagged reduced visibility on the roads as a safety concern while the smoke lingers.
Where the smoke came from
Agencies traced the haze to forest and peat fires in Kalimantan on the Indonesian side of Borneo, which have been burning under dry conditions. The state weather service said a strong dry southwest monsoon, the season locals call habagat, carried the smoke across hundreds of kilometers of sea and spread it over parts of Mindanao, the Visayas, and later Luzon.
The reach was wide. Forecasters warned that the haze could affect western parts of the country, and monitoring stations as far north as Metro Cebu recorded poor air, where some local classes were suspended. In Mindanao the effect was uneven, heavier in some cities and light in others.
How bad it got across the region
The readings varied by location. While the Davao City station sat in the unhealthy for sensitive groups band, a station in Digos, Davao del Sur registered fair air, and one in Malita, Davao Occidental measured good across all parameters. The sharpest numbers came from the neighboring Soccsksargen region, where monitors in Koronadal City briefly reached levels the bureau there labeled very unhealthy and even emergency.
Those spikes were short and local, and most stations in the Davao Region stayed within acceptable ranges. Officials said the pattern reflected how the smoke moved in patches rather than settling evenly over the whole island.
How long it may last
Forecasters expected the haze to hang over parts of the country into early September, with a chance of improvement later in the week if rain returns or the wind shifts direction. Beyond that, they said the outlook depends on whether the fires in Kalimantan keep burning.
Residents were told to base decisions on the latest local readings rather than the look of the sky alone, since fine particles can stay high even when visibility seems to recover. People with asthma or heart and lung conditions were advised to keep medication on hand and seek care if symptoms worsen.
