Singapore Haze Crisis Worsens as Air Quality Reaches Very Unhealthy Levels
Singapore's haze situation worsened on Friday, October 16, 2026, as air pollution reached very unhealthy levels in several parts of the city-state. The smoke, linked to forest and peatland fires in Indonesia, has raised concerns about respiratory health, outdoor activities and the wider impact of air pollution across Southeast Asia.
According to Channel NewsAsia (CNA), Singapore's 24-hour Pollutant Standards Index (PSI) reached 229 in the central region at 3pm on Friday, the highest reading recorded there this year. The east and west regions also entered the very unhealthy range, while the north and south continued to report unhealthy air quality.
Indonesia's Forest Fires Continue to Fuel Regional Haze
The haze affecting Singapore is part of a wider pollution problem across Southeast Asia. Smoke from fires in Indonesia's Sumatra and Kalimantan regions has travelled across borders, with dry weather and wind patterns contributing to the spread.
Singapore's National Environment Agency (NEA) reported that smoke haze from fires in Kalimantan continued to drift towards the country. The agency warned that air quality could remain poor while dry conditions persist in fire-prone areas.
The problem has also affected other countries in the region. Reuters reported on October 14 that air pollution had intensified in Indonesia and neighbouring areas, prompting school closures in East Timor and raising concerns about respiratory illnesses.
Health Risks Increase as Pollution Levels Rise
Haze contains fine particles that can penetrate deep into the lungs. Exposure may cause eye irritation, coughing, a sore throat and breathing difficulties. People with asthma, chronic lung disease or heart conditions may face greater risks, particularly when pollution levels remain high for extended periods.
Children, older adults and pregnant women are among the groups advised to take extra precautions during severe haze episodes. Even people without existing health problems may experience discomfort when exposed to heavily polluted air.
Singapore's Ministry of Health advises residents to use one-hour PM2.5 readings when making immediate decisions about outdoor activities. These readings provide a more current picture of fine-particle pollution, while the 24-hour PSI forecast helps people plan activities for the following day.
Authorities Advise Residents to Limit Outdoor Activities
Singaporean authorities have advised residents to adjust outdoor activities according to the severity of the haze. When air pollution reaches very high levels, even healthy individuals should minimise outdoor activity. Vulnerable groups may need to avoid outdoor activities when pollution levels are high.
Residents who must spend extended periods outdoors during high pollution may consider a well-fitted N95 respirator or an equivalent mask, following official health advice. Ordinary surgical masks do not provide the same level of protection against fine haze particles.
Residents can check local pollution levels and understand the precautions recommended during severe haze. Use our Air Quality Health Advisory Checker to learn how different air quality readings may affect outdoor activities.
People experiencing severe breathing difficulties or chest pain should seek urgent medical attention. Those with existing heart or lung conditions should keep prescribed medication available and follow their healthcare provider's advice.
Singapore Considers Action Over Cross-Border Pollution
The worsening haze has also increased pressure on authorities to address the fires responsible for the pollution. CNA reported that Prime Minister Lawrence Wong said Singapore was investigating companies that may be responsible for forest and peatland fires in Indonesia.
Singapore has indicated that it could take action under its Transboundary Haze Pollution Act where warranted. The issue highlights the difficulty of tackling pollution that originates outside national borders but affects the health and daily lives of neighbouring populations.
When Could the Haze Improve?
The outlook depends largely on rainfall, wind direction and the progress of firefighting efforts in Indonesia. Singapore's weather authorities have forecast showers in some parts of the region, which could help reduce fire activity locally. However, dry conditions may continue in other fire-prone areas, allowing smoke to keep travelling across borders.
Residents should check the latest updates from Singapore's National Environment Agency rather than relying on a single air quality reading. Conditions can change throughout the day as winds shift and weather systems move.
Conclusion
Singapore's worsening haze on October 16 highlights the environmental and public health consequences of Indonesia's ongoing forest and peatland fires. With several regions recording very unhealthy air quality, authorities are urging residents to reduce exposure and monitor official advisories.
Until sustained rainfall and effective fire control improve conditions, haze is likely to remain a concern for parts of Southeast Asia. For residents, checking air quality, limiting strenuous outdoor activities and taking extra care of vulnerable family members remain important precautions.
