Haze conditions in Singapore forecast to ease slightly on Oct 9

NEA says that the forecast 24-hour PSI readings will be in the high moderate to mid-unhealthy range.

Singapore's haze situation on October 9 is expected to improve slightly, according to the National Environment Agency (NEA). The 24-hour Pollutant Standards Index (PSI) readings for the day are forecasted to be in the high moderate to mid-unhealthy range, compared to the unhealthy band previously predicted for October 8. The PSI is a 24-hour rolling average of six key air pollutants.

Since NEA started issuing daily haze advisories on September 4, this is the first time the forecast has fallen within the unhealthy band of 101 and 200. Smoke plumes from southern and central Sumatra and West Kalimantan were observed drifting towards Singapore, with dry conditions expected to persist in neighboring Indonesian territories.

The PSI crossed into the unhealthy range four weeks ago, peaking at 167 in central Singapore on September 29. This marked the first time since October 2023 that the PSI in Singapore reached unhealthy levels due to haze, following warnings of the risk of haze between June and October due to warmer and drier conditions resulting from El Nino and the Indian Ocean Dipole.

Experts predict that the haze in Singapore in 2026 could last longer due to the "Godzilla" El Nino event, which could lead to reduced rainfall and higher temperatures, similar to non-El Nino years.
