Singapore, 08 September 2026 – Partly cloudy conditions were observed over Singapore today. As at 6pm, the 1-hr PM2.5 concentration readings were 32 – 63 μg/m3, in Band 1 – 2 (Normal to Elevated), and the 24-hr PSI was 62 – 74, in the Moderate range.
Update on Hotspot and Haze Situation
- Moderate to dense smoke plumes continue to be observed from the fires in southern and central Sumatra and Kalimantan. Some smoke haze also drifted towards Singapore from isolated nearby fires.
- With dry conditions expected to persist over southern Sumatra and parts of Kalimantan in the coming days, there remains a risk of smoke haze. The 24-hr PSI for Singapore is forecast to be in the Moderate – Low Unhealthy range.
Activity Guidelines
- The health impact of haze is dependent on one’s health status, the PSI level, and the length and intensity of outdoor activity. For immediate outdoor activities, please check the 1-hr PM2.5 concentration readings and personal guide. Use the 24-hr PSI forecast and corresponding health advisories for planning next day outdoor activities.
