Singapore air quality remains in moderate range

Amid the ongoing dry conditions, moderate to dense smoke plumes from fires in southern and central Sumatra, as well as West Kalimantan, continued to drift towards Singapore, the agency said.

While some showers are forecast over Kalimantan, dry conditions are expected over Singapore and the surrounding region in the coming days.

With prevailing winds blowing from the southeast or south, there remains a risk of haze affecting Singapore should the fires persist.

NEA forecast the 24-hour PSI for Singapore to be in the high-moderate to low-unhealthy range over the 24 hours from 6pm.

The 24-hour PSI in the central region entered the unhealthy band of 101 to 200 at 7am on Friday, marking the first time the PSI had exceeded 100 since Oct 8, 2023.

This led NEA to start issuing daily haze advisories, including a 24-hour PSI forecast, to help the public plan activities and events for the following day.

The PSI would later also cross into the unhealthy range in both eastern and western Singapore.
