The Singapore Environmental Protection Department reported on October 15, 2026, that the Pollutant Standards Index (PSI) in the western part of the city reached 208. This marks the highest level recorded during the current haze season.
The PSI, which measures air quality, exceeded the previous seasonal high of 205 recorded in 2025. The reading was taken at a monitoring station in Bukit Timah, a residential area known for its dense vegetation. The high PSI level is attributed to a combination of smoke from forest fires in Indonesia and local emissions.
This is the third consecutive week of elevated PSI readings in Singapore, with the city experiencing persistent haze due to transboundary air pollution. The government has issued health advisories, urging residents to limit outdoor activities and use air filters. The situation follows a series of severe haze episodes in recent years, highlighting the ongoing challenge of managing air quality in the region.
