Singapore’s air quality worsens, all regions record unhealthy levels

Singapore's air quality has worsened across all regions, with the National Environment Agency reporting unhealthy levels throughout the country. The Central region experienced the highest 24-hour Pollutant Standards Index (PSI) of 166 at 11 am on Tuesday, followed by the West at 149, East at 136, South at 132, and North at 108. The 24-hour PSI measures daily air quality and signals a health advisory when readings fall between 101 and 200, indicating unhealthy conditions.

Meanwhile, the Asean Specialised Meteorological Centre reported moderate transboundary smoke haze affecting parts of Peninsular Malaysia, Singapore, and the northwestern regions of Borneo. Smoke plumes were also observed emanating from hotspot clusters in large parts of Kalimantan and the central and southern areas of Sumatra. Numerous air quality stations in Borneo, Sumatra, Singapore, and certain areas of Peninsular Malaysia are recording unhealthy to hazardous levels.
