Indonesia Wildfires 2026: Haze Exposes 12.5 Million People
Indonesia Wildfires 2026 have created a serious air-quality crisis, with more than 12.5 million people exposed to hazardous haze across parts of the country.
The fires are especially severe in parts of Borneo and Sumatra. West Kalimantan has been among the worst-hit areas. Thick smoke has reduced visibility in several locations and made outdoor conditions difficult for residents.
Indonesia is facing its most intense wildfire season in more than a decade. Experts have linked the worsening fires to hot and dry weather, drought and the effects of a strong El Niño pattern. Dry vegetation has allowed fires to spread more easily.
The health impact is also increasing. Indonesian Health Ministry data showed that wildfire-related respiratory illness cases across seven affected provinces reached 113,336 by September 9. This was more than double the 50,891 cases recorded on September 1.
Health workers have reported more people seeking help for breathing problems, coughing and other symptoms linked to the smoke. Volunteers in West Kalimantan have also been providing oxygen cylinders to residents and firefighters affected by the haze.
The smoke has also moved beyond Indonesia. Air quality has been affected in parts of Malaysia and Singapore, highlighting the wider regional impact of the fires.
Heavy haze has reduced visibility in West Kalimantan and disrupted some flights. Pontianak has experienced particularly poor conditions, with visibility falling below one kilometre during periods of heavy smoke.
Indonesia has increased firefighting operations, including aerial water bombing and cloud-seeding efforts. More than 50 aircraft have been deployed to help fight the fires.
Japan has also provided three CH-47 Chinook helicopters and personnel to support firefighting operations in Borneo. Malaysia has offered additional aerial assistance.
Officials have warned that the fires could continue into October or early November if dry conditions persist. Authorities are continuing firefighting and health-response efforts as hazardous haze remains a concern across Indonesia and neighbouring count.
