SINGAPORE - The air quality in Singapore continued to improve early on Sept 16, with the 24-hour PSI in four of the five regions resting in the moderate range. At 6am, only the central region remains at 103, above the 101 threshold that marks an unhealthy quality on the Pollutant Standards Index (PSI). The central region includes the Thomson, Marymount, Sin Ming, Ang Mo Kio, Bishan, Serangoon Gardens, MacRitchie and Toa Payoh areas, according to the National Environment Agency (NEA) website.

The PSI stood at 87 for the east, 86 for the west, 78 for the north and 76 for the south at 6am on Sept 16.

This is in stark contrast to the day before, when unhealthy levels of pollutants were recorded all across the country, a first since September 2019. Air quality is considered unhealthy when the 24-hour PSI is in the range of 101 to 200, during which the NEA advises the public to reduce outdoor activities. PSI readings of 51 to 100 are considered moderate, while values of zero to 50 are in the “good” range. The conditions on Sept 15 prompted some organisations such as the Football Association of Singapore to implement measures to mitigate the impact of the haze.

In an advisory on Sept 15, NEA said air quality in Singapore for the next 24 hours was forecast to be in the high moderate to mid-unhealthy range.

Dry conditions are expected over central and southern Sumatra and southern Kalimantan in neighbouring Indonesia - where forest fires have raged for weeks - in the coming days, NEA added.

“With the prevailing winds forecast to continue blowing from the south-east to east-south-east, there is a risk of smoke haze affecting Singapore,” the agency said.

The PSI crossed into the unhealthy range two weeks ago, hitting 101 in central Singapore on the morning of Sept 4. In the days that followed, readings in the central, eastern and western parts of Singapore occasionally crossed into the unhealthy range. September’s developments mark the first time since October 2023 that the PSI in Singapore hit unhealthy levels because of haze, with the authorities earlier warning of the risk of haze between June and October as a result of warmer and drier conditions brought on by both El Nino and the Indian Ocean Dipole.

9月15日下午2点52分，从丹戎巴葛地区公园向圣淘沙方向望去，可以看到雾霾天气。

新加坡——9月16日清晨，新加坡空气质量持续改善，五个区域中有四个区域的24小时空气污染指数（PSI）处于中等水平。截至早上6点，仅中部区域的PSI仍为103，高于101的“不健康”阈值。根据国家环境局（NEA）网站的信息，中部区域包括汤申、玛丽蒙、信明、宏茂桥、碧山、实龙岗花园、麦里芝和Toa Payoh地区。

9 月 16 日上午 6 点，东部 PSI 指数为 87，西部为 86，北部为 78，南部为 76。

这与前一天的情况形成鲜明对比，前一天全国各地都记录到不健康的污染物浓度，这是自2019年9月以来的首次。当24小时空气污染指数（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至100之间被认为是中等的，而0至50则属于“良好”范围。9月15日的空气质量状况促使一些机构，例如新加坡足球总会，采取措施来减轻雾霾的影响。

新加坡国家环境局 (NEA) 在 9 月 15 日发布的公告中表示，预计未来 24 小时内新加坡的空气质量将处于中度至中度不健康水平。

尼泊尔国家环境局补充说，未来几天，苏门答腊中部和南部以及邻国印度尼西亚的加里曼丹南部（森林大火已肆虐数周）预计将出现干燥天气。

该机构表示：“由于预计盛行风向将继续从东南吹向东南偏东，新加坡有受到烟霾影响的风险。”

两周前，新加坡空气污染指数（PSI）突破不健康范围，9月4日上午，新加坡中部地区的PSI指数达到101。此后几天，新加坡中部、东部和西部地区的PSI指数也时有突破不健康范围。这是自2023年10月以来，新加坡的PSI指数首次因雾霾达到不健康水平。此前，由于厄尔尼诺现象和印度洋偶极子带来的气候变暖干燥，当局曾警告称，6月至10月期间存在雾霾风险。
