Haze blankets Singapore as PM2.5 levels spike across three regions

Hourly PM2.5 measurements climbed into the high band across three regions at 1pm, with the western zone registering 195 micrograms per cubic metre, the southern zone at 173, and the eastern zone at 160. These readings underscore the deteriorating air quality that has affected residents island-wide as transboundary haze continues to drift over Singapore's airspace.

The persistent haze has prompted health authorities to advise vulnerable groups—including children, the elderly, and those with respiratory or cardiovascular conditions—to limit outdoor activities. The National Environment Agency's 24-hour PM2.5 index remained in the unhealthy band across all monitoring stations throughout the day.

Transboundary air pollution, typically stemming from agricultural fires and industrial emissions in neighbouring regions during the dry season, has historically contributed to seasonal haze episodes affecting Singapore. Residents are advised to monitor real-time air quality updates and adopt appropriate precautions, including the use of masks when venturing outdoors during peak pollution hours.

The agency said it would continue monitoring air quality conditions and issue updates as the situation develops. Authorities have not indicated when air quality levels are expected to return to acceptable ranges.
