Haze potential in Singapore as fires intensify in Sumatra and Kalimantan

AI-summarized · Neutrality-checked

On August 24, 2026, Singapore's National Environment Agency (NEA) warned of potential haze due to an increase in hotspot activity and smoke plumes in Kalimantan and southern Sumatra. Prevailing winds from the south and southeast, combined with persistent dry conditions, caused the NEA to note a risk of smoke reaching Singapore, where air quality remained in the moderate range with a 24-hour PSI of 68 to 90. The ASEAN Specialised Meteorological Centre raised its alert to Level 2 for the southern ASEAN region, reflecting an increased risk of transboundary haze.

Consequences

If the 24-hour PSI surpasses 100, the Singaporean government’s inter-agency haze task force, comprised of 28 public agencies, is prepared to implement tiered action plans to manage the impact of the worsening air quality. The NEA also committed to issuing daily haze advisories should the air quality reach the unhealthy range.
