Singapore, 8 October 2023 – The haze situation in Singapore improved today. As at 5pm, the 1-hr PM2.5 concentration readings were 10-18 µg/m3, in Band I (Normal), and the 24-hr PSI was 57-86, in the Moderate range.
Update on Hotspot and Haze Situation
2 Dry conditions persisted over most parts of Singapore and the surrounding region. 68 hotspots were detected mostly over the southern and central parts of Sumatra today, lower than the 188 hotspots detected yesterday. Moderate to dense smoke haze was observed from satellite imagery over central and southern Sumatra, blowing towards the northwest by prevailing winds.
3 The prevailing winds are forecast to blow mainly from the east tomorrow, lowering the likelihood of transboundary haze affecting Singapore. Showers are also expected over Singapore and the surrounding region which could bring about some improvement to the regional haze situation. For the next 24 hours, the 24-hr PSI for Singapore is forecast to be in the Moderate 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.
