Air quality back into unhealthy range in central, west Singapore

Air quality in central Singapore once again reached the unhealthy range at 9pm on Sunday, October 4. The 24-hour Pollutant Standards Index (PSI) reading in the central region stood at 101, while other regions remained moderate. At that same time, the 1-hour PM2.5 reading in the central region was elevated, indicating poor air quality at a specific point in time.

The National Environment Agency (NEA) reported that dense smoke plumes from southern Sumatra and fires in Kalimantan were drifting towards Singapore, contributing to the haze. The NEA warned that dry weather would continue, posing a risk of smoke haze under prevailing winds. They advised individuals to consider their health status, the current PSI level, and planned outdoor activities when assessing the health impact of the haze.
