Singapore’s air quality reached its most severe levels of 2026 this week as smoke from forest and peatland fires in Indonesia drifted across the city-state. On Oct 15, the 24-hour Pollutant Standards Index (PSI) in western Singapore hit a “very unhealthy” level of 212, according to reports.
Government Response to Transboundary Haze
Wong stated on social media that the government is investigating companies potentially responsible for the fires in Indonesia. The government is also exploring collaborative efforts with regional partners to address the crisis.
Singapore’s National Environment Agency (NEA) reported that dry conditions and prevailing southeasterly winds have driven dense smoke from Kalimantan and Sumatra toward the island. To mitigate health risks, the Haze Task Force has begun distributing N95 masks to vulnerable residents, including pregnant women, children, and those with underlying medical conditions, via vending machines at community clubs.

Regional Impact on Aviation and Daily Life
The low visibility caused by the smoke has disrupted local infrastructure. Changi Airport Group and the Civil Aviation Authority of Singapore confirmed that 16 flights were diverted from Seletar Airport due to the haze, CNBC reported.
Outdoor businesses are also feeling the pressure. Marina Bay Sands has temporarily suspended certain outdoor guest experiences, while hawker centers and outdoor dining establishments have reported a decline in customers. For delivery workers, the situation is increasingly difficult.
Escalating Tensions Across Southeast Asia
The haze has affected countries beyond Singapore, leading to mounting regional frustration. Reuters reports that East Timor suspended face-to-face classes for three days starting October 15, while schools in parts of Malaysia were also forced to close.
In Indonesia, the scale of the fires has intensified significantly. Official data cited by Reuters indicates that the number of firefighting personnel deployed by Jakarta has increased to more than 69,000. Despite these efforts, air quality in the province of Central Kalimantan reached an ISPU index reading of 1,200 on October 14, four times the “hazardous” threshold of 300.
Some regional officials are calling for a tougher stance. Malaysian lawmaker Syed Saddiq Syed Abdul Rahman suggested that neighboring governments should lodge formal diplomatic protests and consider restricting financing for Indonesian companies linked to land burning, according to The Diplomat.
Unresolved Questions Regarding Air Quality
While authorities in Singapore and the broader region continue to monitor the situation, the timeline for improvement remains uncertain. While Singapore has signaled its readiness to provide assistance to Indonesian officials, the effectiveness of regional coordination remains a subject of ongoing debate among Southeast Asian leaders.

Frequently Asked Questions
How does the current haze compare to past incidents?
The recent pollution levels are the highest recorded in Singapore since 2015, when PM2.5 levels reached a national record of 471 micrograms per cubic meter, according to Reuters.
What should residents do during the haze?
The NEA advises individuals to reduce outdoor physical exertion and use the 24-hour PSI forecast to plan activities. Those who must be outdoors for extended periods during hazardous conditions are advised to wear an N95 mask that fits properly.
Are schools currently closed in Singapore?
While East Timor and parts of Malaysia have mandated school closures, the Singapore government has focused on distributing masks and providing air-conditioned "haze shelters" at community centers rather than announcing a nationwide school shutdown.
