Air quality in Singapore’s central region back in unhealthy range as PSI hits 102
NEA said air quality is forecast to be in the moderate and unhealthy range.
Singapore's central region has once again entered the unhealthy air quality range, with a 24-hour Pollutant Standards Index (PSI) reading of 102, according to official readings from the National Environment Agency (NEA) as of September 14. The PSI had previously crossed into the unhealthy range on September 4, hitting 101 in central Singapore.
Since then, readings in the central, eastern, and western parts of Singapore have occasionally crossed into the unhealthy range, but have since fallen back into the moderate spectrum as of September 11. This marks the first time the PSI in Singapore has reached unhealthy levels due to haze since October 2023, with authorities warning of the risk of haze between June and October due to warmer and drier conditions brought on by El Nino and the Indian Ocean Dipole.
The NEA forecasts that air quality for the next 24 hours will be in the moderate and lower end of the unhealthy range, with moderate to dense smoke plumes observed drifting towards Singapore from fires in Kalimantan and southern Sumatra.
