SINGAPORE – The haze situation here did not ease overnight as the air quality across the island remained in the unhealthy range.

As at 6am on Oct 9, the 24-hour Pollutant Standards Index (PSI) readings stood at 109 in the north, 135 in the south,134 in the east, 155 in the west and 159 in the central region.

Air quality is considered unhealthy when the PSI – a 24-hour rolling average of six key air pollutants – is in the range of 101 to 200.

Meanwhile, PM2.5 readings were elevated across all regions in Singapore, led by the west at 143, central at 140, south at 134, east at 117 and north at 92.

The hourly PM2.5 reading is used as a gauge for immediate air quality, with scores from 56 to 150 indicating elevated pollution levels while values of 151 to 250 represent high pollution levels.

The highest PSI reading of the year – 167 i n central Singapore – was recorded on Sept 29. That same day, the central region also saw the highest 1-hour PM2.5 reading of 2026 of 165 at midnight.

In its daily advisory on the evening of Oct 8, the National Environment Agency (NEA) forecast that the 24-hour PSI readings will be in the high moderate to mid-unhealthy range.

NEA said moderate to dense smoke plumes from southern and central Sumatra and West Kalimantan were observed to be drifting towards Singapore, with dry conditions expected to continue in the neighbouring Indonesian territories.

“Under the prevailing south-easterly or southerly winds, smoke haze may continue to drift towards Singapore,” it added.

新加坡——一夜之间，这里的雾霾情况并未缓解，全岛空气质量仍处于不健康水平。

截至 10 月 9 日上午 6 点，24 小时污染物标准指数 (PSI) 读数北部为 109，南部为 135，东部为 134，西部为 155，中部地区为 159。

当 PSI（六种主要空气污染物的 24 小时滚动平均值）在 101 到 200 之间时，空气质量被认为是不健康的。

与此同时，新加坡所有地区的 PM2.5 读数均升高，其中西部最高，达 143，中部最高，达 140，南部最高，达 134，东部最高，达 117，北部最高，达 92。

每小时 PM2.5 读数被用作衡量即时空气质量的指标，56 至 150 的分数表示污染水平升高，而 151 至 250 的值表示污染水平极高。

今年新加坡中部地区的最高空气污染指数（PSI）读数——167——出现在9月29日。同一天，中部地区午夜时分的1小时PM2.5读数也达到了2026年以来的最高值165。

国家环境局 (NEA) 在 10 月 8 日晚间的每日公告中预测，24 小时空气污染指数 (PSI) 将处于中度至中度不健康范围内。

新加坡国家环境局表示，来自苏门答腊南部和中部以及西加里曼丹的中等至浓重烟雾正向新加坡飘去，预计邻近的印尼领土将继续保持干燥天气。

“在盛行的东南风或南风的影响下，烟雾可能会继续向新加坡飘去，”声明补充道。
