Haze Situation Update (14 October 2023)

Singapore, 14 October 2023 – Singapore experienced generally fair and warm weather today. As at 5pm, the 1-hr PM2.5 concentration readings were 11-26 µg/m3, in Band I (Normal), and the 24-hr PSI was 52-69, in the Moderate range.

Update on Hotspot and Haze Situation

2    Most parts of the surrounding region remained dry today, except for a few showers in northern Sumatra. 68 hotspots were detected mostly in the southern and central parts of Sumatra, lower than the 126 hotspots detected yesterday. Moderate to dense smoke haze was observed over parts of southern and central Sumatra from satellite imagery, drifting towards the north and northwest.

3 For the next few days, the dry conditions over Singapore and the surrounding region are forecast to continue, with prevailing winds likely to blow from the south, and occasionally from the southwest. There is a chance of slight haze affecting Singapore if the regional haze situation escalates. 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.
