What could the transboundary haze from Indonesian fires mean for the Philippines?

Already happening What happens if… A possibility worth considering, not a forecast.

Transboundary haze from Indonesian fires is degrading air quality in the Philippines. The transboundary haze originating from massive forest and peatland fires in Indonesia's Kalimantan and Sumatra has reached the Philippines, causing poor air quality. This haze consists of smoke, ash, dust, and microscopic PM2.5 particles, which are carried by winds associated with the southwest monsoon (habagat). The Department of Health has warned that exposure to these pollutants may cause difficulty breathing, coughing, chest pain, eye irritation, or worsen existing lung conditions such as asthma, requiring Filipinos to take specific precautions like staying indoors and wearing N95 masks.

  • Pollutants have been carried toward the Philippines by winds associated with the southwest monsoon (habagat).philstar.com
  • Exposure to haze may cause difficulty breathing, coughing, chest pain, eye irritation or watery eyes.philstar.com
  • It may also worsen existing lung conditions such as asthma.philstar.com

Why it matters

The health risks posed by transboundary haze are significant, particularly for vulnerable groups such as children, older adults, pregnant women, and people with pre-existing heart or lung conditions. The Department of Health has advised these groups to take extra precautions and keep their medications readily available.

This haze crisis is part of a larger regional climate-health challenge, where extreme weather events like El Niño intensify forest fires. These events place growing pressure on public health systems across Southeast Asia, highlighting the need for regional cooperation to manage environmental risks.
