The smoke doesn't stay put. It drifts across borders into millions of lungs.
In Bali, environment ministers from six ASEAN nations confronted a sobering convergence: fire hotspots across southern ASEAN have nearly doubled in the first half of 2026, and the meteorological forces gathering on the horizon — El Niño, a positive Indian Ocean Dipole, and seasonal winds that carry no regard for borders — threaten to deepen the crisis through year-end. Transboundary haze is not merely a weather event but a recurring test of whether neighboring nations can subordinate sovereign instincts to shared vulnerability. The ministers gathered not in panic, but with the measured urgency of people who understand that the window for coordinated action is narrow, and the cost of inaction is measured in the lungs of millions.
- Hotspot counts across southern ASEAN surged 86% in the first half of 2026, driven by prolonged dry spells in January, March, and April — a near-doubling that alarmed officials before the worst of the season had even arrived.
- El Niño conditions that took hold in June are forecast to intensify between August and September, while a positive Indian Ocean Dipole threatens to suppress rainfall further, creating a compounding fire risk that meteorologists are watching with deep concern.
- Prevailing southwesterly and southeasterly winds will carry smoke indiscriminately across national borders, exposing millions of people in multiple countries to dangerous air quality and serious respiratory health consequences.
- Ministers from Brunei, Indonesia, Malaysia, Singapore, Thailand, and Timor-Leste reaffirmed commitments to existing regional frameworks and pressed member states to complete ratification of the ASEAN Coordinating Centre for Transboundary Haze Pollution Control before conditions worsen.
- Malaysia is deploying additional automated weather stations in peatland forests and launching a real-time air quality forecasting system, offering communities earlier warning — a practical lifeline as the region braces for a difficult second half of the year.
In Bali on Thursday, environment ministers from six ASEAN nations gathered under the weight of a troubling statistic: active fire hotspots across southern ASEAN had nearly doubled in the first half of 2026, an 86 percent surge driven by prolonged dry conditions in January, March, and April. The meeting of the Sub-Regional Ministerial Steering Committee on Transboundary Haze Pollution brought together senior officials from Brunei Darussalam, Indonesia, Malaysia, Singapore, Thailand, and Timor-Leste — and the meteorological data they reviewed offered little comfort about what lies ahead.
El Niño conditions that took hold in June are expected to persist and intensify between August and September. A positive Indian Ocean Dipole, forecast to develop between July and August, will suppress rainfall across much of southern ASEAN. Together, these patterns create near-ideal conditions for fire activity to accelerate and for smoke to travel across borders on prevailing southwesterly and southeasterly winds — threatening the air quality and respiratory health of millions across the region.
The ministers reaffirmed their commitment to coordinated action through existing frameworks, including the ASEAN Agreement on Transboundary Haze Pollution and the Haze-Free Roadmap. A central priority is operationalizing the ASEAN Coordinating Centre for Transboundary Haze Pollution Control, designed to centralize the regional response. Indonesia has been developing the legal and operational groundwork for the centre, and Vietnam has already approved the establishment agreement; other member states were urged to complete their domestic ratification processes without delay.
On the ground, Malaysia's meteorological department is strengthening the Southeast Asia Fire Danger Rating System by deploying automated weather stations in peatland forests and launching a real-time air quality forecasting system to give communities earlier warning. Ministers also endorsed an investment framework for haze-free sustainable land management aligned with the region's peatland strategy through 2030 — an effort to address the root causes of fire, not merely its consequences. The next ministerial meeting is scheduled for Da Nang, Vietnam, in October 2026, as the region enters what the data suggests will be a difficult and smoky second half of the year.
In Bali on Thursday, environment ministers from six ASEAN nations gathered to confront a troubling trend: the number of active fire hotspots across southern ASEAN had nearly doubled in the first half of 2026. The surge—an 86 percent jump compared to the same period the year before—signals a dangerous escalation in the conditions that breed transboundary haze, the seasonal smoke that drifts across borders and chokes millions of people across the region.
The meeting of the Sub-Regional Ministerial Steering Committee on Transboundary Haze Pollution brought together senior officials from Brunei Darussalam, Indonesia, Malaysia, Singapore, Thailand, and Timor-Leste. Brunei's delegation was led by Deputy Minister of Development Dayang Dr Nor Imtihan binti Haji Abd Razak, accompanied by environmental and development officials. The timing of their gathering was urgent: the meteorological data they reviewed painted a picture of worsening conditions ahead.
According to the ASEAN Specialised Meteorological Centre, the spike in hotspots stemmed from prolonged dry weather that gripped much of the region during January, March, and April. But the real concern lies in what comes next. El Niño conditions, which took hold in June, are expected to persist through the remainder of 2026 and intensify between August and September. Simultaneously, a positive Indian Ocean Dipole is forecast to develop between July and August, bringing below-normal rainfall across much of southern ASEAN. These converging weather patterns create the perfect conditions for fire activity to accelerate and smoke to spread. The prevailing southwesterly and southeasterly winds will carry that smoke across national boundaries, affecting air quality and public health in multiple countries at once.
The ministers reaffirmed their commitment to a coordinated regional response, anchoring their efforts in existing frameworks: the ASEAN Agreement on Transboundary Haze Pollution, the Haze-Free Roadmap, and the ASEAN Standard Operating Procedure for Monitoring, Assessment and Joint Emergency Response. They also emphasized the importance of establishing and operationalizing the ASEAN Coordinating Centre for Transboundary Haze Pollution Control, a body designed to centralize the region's response. Indonesia has been preparing the legal framework and operational structure for this centre, while Vietnam has already approved the establishment agreement. Other member states were urged to complete their domestic ratification processes so the centre can begin functioning.
Beyond institutional measures, the ministers endorsed an implementation plan for the ASEAN Investment Framework for Haze-Free Sustainable Land Management, which aligns with the region's peatland management strategy through 2030. The focus here is on addressing root causes—the forest and peatland fires themselves—through sustainable land management and agricultural practices that do not rely on fire. Malaysia's meteorological department has been strengthening the Southeast Asia Fire Danger Rating System by deploying additional automated weather stations in peatland forests and launching a real-time air quality forecasting system to give communities earlier warning of deteriorating conditions.
The ministers also agreed to explore science diplomacy as a tool within the haze pollution framework and to examine ways of strengthening the ASEAN Transboundary Haze Pollution Control Fund through expanded contributions and scientific research. The next round of meetings will take place in Da Nang, Vietnam, in October 2026, with Malaysia hosting the 28th Ministerial Steering Committee Meeting in 2027. For now, the region braces for what the data suggests will be a difficult second half of the year.

Why does an 86 percent surge in hotspots matter if we're just talking about fire activity? Isn't that a regional problem?
It becomes a regional problem because of wind patterns and geography. When fires burn in Indonesia or Malaysia, the smoke doesn't stay put. It drifts across borders into Singapore, Thailand, and beyond. Millions of people in multiple countries breathe the same air.
So this is really about air quality and health across borders?
Exactly. Transboundary haze isn't just an environmental nuisance—it's a public health crisis that no single country can solve alone. That's why these ministers had to sit down together.
What's the connection between El Niño and the fires themselves?
El Niño brings drier conditions. Drier conditions mean vegetation is more flammable. Whether fires start naturally or are set deliberately for land clearing, they spread faster and burn hotter when the ground is parched. The meteorological centre is forecasting that pattern to intensify through August and September.
If they know this is coming, why aren't they just banning the fires now?
That's the harder question. Enforcement is difficult across a region with different governments and economic pressures. What they're trying to do is build institutional capacity—the coordinating centre, better monitoring systems, shared protocols—so that when fires do start, the response is faster and more coordinated.
And if they don't get that centre operational in time?
Then you get what happened in previous years: smoke choking cities, schools closing, hospitals overwhelmed with respiratory cases, and each country scrambling separately instead of acting as a region.
