Singapore, 03 October 2026 – It was fair over Singapore today. As at 5pm, the 1-hr PM2.5 concentration readings were 30 – 56 µg/m3, in (Band 1, Normal / Band 2, Elevated), and the 24-hr PSI was 79 -104 in the Moderate to Unhealthy range.
Update on Hotspot and Haze Situation
2 Moderate to dense smoke plumes from southern Sumatra were observed to drift towards Singapore and the surrounding region. Smoke haze was also observed from fires in Kalimantan.
3 Dry weather conditions are forecast to persist over Singapore and the surrounding region tomorrow. With the prevailing southeasterly or southwesterly winds expected to strengthen, there remains a risk of smoke haze affecting Singapore. The 24-hr PSI for Singapore is forecast to be in the High Moderate to Low 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.
