Singapore faces unhealthy haze from Sumatra and Kalimantan

Singapore is experiencing a haze situation as smoke from southern Sumatra and Kalimantan drifts toward the city-state. As of September 30, 2026, the 24-hour Pollutant Standards Index (PSI) was recorded in the moderate to unhealthy range, between 91 and 112.

While recent showers provided some improvement, dry conditions are expected to persist in southern Sumatra and parts of Kalimantan. Prevailing southeasterly or southerly winds maintain the risk of smoke haze affecting Singapore. Residents have reported physical symptoms such as headaches and throat irritation, with social media users documenting reduced visibility of landmarks like Marina Bay Sands and the Singapore Flyer.

The National Environment Agency advises citizens to monitor 1-hour PM2.5 concentration readings and use PSI forecasts to plan outdoor activities, noting that health impacts depend on individual health status and the intensity of exposure.
