Singapore, 14 September 2026 – Brief showers fell over a few parts of Singapore today. As at 5pm, the 1-hr PM2.5 concentration readings were 56 – 115 μg/m3, in Band 2 (Elevated), and the 24-hr PSI was 88 – 117, in the Moderate to Unhealthy range.
Update on Hotspot and Haze Situation
2. Due to a shift in the prevailing winds to blow from east-southeast, moderate to dense smoke plumes from fires in Kalimantan drifted towards Singapore. Some smoke haze was also observed to drift from southern Sumatra.
3. Dry conditions are forecast over Singapore and the surrounding region in the coming days. With the prevailing winds forecast to continue blowing from the southeast to east-southeast, Singapore will likely be affected by smoke haze. The 24-hr PSI for Singapore is forecast to be in the High Moderate – Mid Unhealthy range.
Activity Guidelines
4. 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.
