SINGAPORE – Hazy conditions across Singapore continued overnight, with the 24-hour Pollutant Standards Index (PSI) for all regions staying within the unhealthy range and the one-hour PM2.5 readings largely within the elevated range.

At 6am on Oct 14, the 24-hour PSI reading stood at 143 in the central region, 107 in the north, 123 in the south, 142 in the east and 145 in the west.

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.

The hourly PM2.5 readings – measured in micrograms per cubic m and used as a gauge for current air quality – were in the elevated zone across the island at 6am: central (96), north (60), south (74), east (91) and west (82).

PM2.5 scores from 0 to 55 represent normal values, those between 56 and 150 indicate an elevated concentration of fine particles, while those between 151 and 250 are considered high.

The PM2.5 reading in the east briefly dropped out of the elevated range at 5am, with a reading of 54.

In its daily haze advisory in the evening of Oct 13, the National Environment Agency (NEA) forecast the PSI for Singapore to be in the unhealthy range for the next 24 hours.

It said: “Moderate to dense smoke plumes were observed from fires in Kalimantan and southern Sumatra. Smoke haze was observed drifting towards Singapore under the prevailing south-easterly winds.”

While some showers are expected over Singapore and parts of the surrounding region, dry conditions are forecast to persist over parts of southern Sumatra and Kalimantan, NEA said.

For the first time since October 2023, air quality in Singapore breached unhealthy levels on Sept 4. The NEA started issuing daily haze advisories since the evening of that day.

The PSI reached a peak for 2026 on Oct 9, reaching 192 in the central region between 5pm and 8pm.

Similarly, the highest hourly PM2.5 reading to date in 2026 – 171 – was recorded in the west at 2am that same day.

The haze task force announced on the evening of Oct 9 that, among other measures, it will distribute N95 masks to eligible Singaporeans when air quality hits “very unhealthy” levels.

Such levels are denoted by a PSI reading of between 201 and 300.

新加坡——新加坡各地一夜之间雾霾天气持续，所有地区的 24 小时污染物标准指数 (PSI) 均处于不健康范围内，一小时 PM2.5 读数也大多处于较高水平。

10 月 14 日上午 6 点，24 小时 PSI 读数中部地区为 143，北部为 107，南部为 123，东部为 142，西部为 145。

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。

早上 6 点，全岛 PM2.5 小时读数（以每立方米微克为单位测量，用作衡量当前空气质量的指标）处于较高水平：中部 (96)、北部 (60)、南部 (74)、东部 (91) 和西部 (82)。

PM2.5 值从 0 到 55 代表正常值，56 到 150 表示细颗粒物浓度升高，而 151 到 250 则被认为是高浓度。

早上 5 点，东部地区的 PM2.5 读数短暂地从高位降至 54。

新加坡国家环境局 (NEA) 在 10 月 13 日晚间发布的每日雾霾预警中预测，未来 24 小时内新加坡的空气污染指数 (PSI) 将处于不健康范围。

报告称：“加里曼丹岛和苏门答腊南部发生火灾，观测到中等至浓重的烟柱。在盛行的东南风作用下，烟雾向新加坡方向飘移。”

国家环境局表示，虽然新加坡及周边地区预计会有一些阵雨，但苏门答腊南部和加里曼丹部分地区预计将持续干燥天气。

9月4日，新加坡的空气质量自2023年10月以来首次突破不健康水平。国家环境局从当天晚上开始发布每日雾霾预警。

2026 年 10 月 9 日，PSI 指数达到峰值，中部地区下午 5 点至晚上 8 点达到 192。

同样，2026 年迄今为止最高的 PM2.5 小时读数——171——是在同一天凌晨 2 点在西部地区记录到的。

雾霾工作组于 10 月 9 日晚宣布，除其他措施外，当空气质量达到“非常不健康”的水平时，将向符合条件的新加坡人分发 N95 口罩。

这种水位用 PSI 读数在 201 到 300 之间表示。
