SINGAPORE – Air quality in central Singapore has approached the unhealthy range, with 24-hour Pollutant Standards Index (PSI) in the region standing at 100 as at 10pm on Sept 9.
Readings in the other regions remained in the moderate range.
Haze in Singapore began observing an uptick again recently when the PSI in the central part crossed 101 early on Sept 4.
Since then, readings in central, eastern and western parts of Singapore have occasionally crossed into the unhealthy range before dipping back into the moderate spectrum.
In an advisory on Sept 9, the National Environment Agency (NEA) said the 24-hour PSI is forecast to range from higher end of the moderate category to the lower end of the unhealthy spectrum.
NEA added that it continues to observe moderate to dense smoke plumes from fires in southern and central Sumatra as well as Kalimantan, adding that some haze also drifted towards Singapore.
“With prevailing winds blowing from the south-east or south, there remains a risk of smoke haze affecting Singapore should the fires persist,” the agency said.
The recent developments mark the first time PSI in Singapore hit unhealthy levels due to haze since October 2023.
Air quality is considered unhealthy when the PSI is in the range of 101 to 200, during which NEA advises the public to cut down on outdoor activities.
PSI readings of 51 to 100 are considered moderate, while values of 0 to 50 are in the “good” range.

新加坡——截至9月9日晚上10点,新加坡中部地区的空气质量已接近不健康范围,该地区的24小时污染物标准指数(PSI)为100。
其他地区的读数仍处于中等水平。
新加坡的雾霾最近再次出现上升趋势,9 月 4 日清晨,中部地区的 PSI 指数超过 101。
从那时起,新加坡中部、东部和西部地区的读数偶尔会进入不健康范围,然后又回落到中等范围。
国家环境局 (NEA) 在 9 月 9 日发布的公告中表示,预计 24 小时空气污染指数 (PSI) 将从中等水平的较高值到不健康水平的较低值不等。
新加坡国家环境局补充说,他们继续观察到苏门答腊南部和中部以及加里曼丹的火灾产生的中等至浓重的烟雾,并补充说,一些烟雾也飘向了新加坡。
该机构表示:“由于盛行风向为东南风或南风,如果火势持续,新加坡仍有可能受到烟霾影响。”
最近的事态发展标志着自 2023 年 10 月以来,新加坡的空气污染指数 (PSI) 首次因雾霾达到不健康水平。
当空气污染指数(PSI)在 101 至 200 之间时,空气质量被认为是不健康的,此时国家环境局建议公众减少户外活动。
PSI读数在51到100之间被认为是中等的,而0到50之间的数值则属于“良好”范围。
