Singapore’s haze stayed overnight, with the 24-hour PSI unhealthy in all regions. The west was highest at 173, and the central region reached 166.

NEA said smoke from fires in Kalimantan and southern Sumatra was drifting to Singapore under south-easterly winds. Dry conditions there may keep the haze going.

The haze task force announced measures on Oct 9 if PSI rises above 200. This follows 2026 peaks of 192 PSI in the central region and PM2.5 at 171 in the west.

SINGAPORE – Hazy conditions across Singapore remained overnight, with the 24-hour PSI for all regions staying within the unhealthy range.

At 6am, the highest 24-hour Pollutant Standards Index reading was recorded in the west at 173, followed by the central region (166), the east (148), the south (131) and the north (126).

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 for four regions of Singapore: central (110), east (99), west (97) and south (76).

Only the north region (55) recorded readings in the normal zone, at the threshold of entering the elevated band.

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.

In its daily haze advisory in the evening of Oct 12, the National Environment Agency (NEA) forecast the 24-hour PSI for Singapore to be in the unhealthy range.

It said: “Moderate to dense smoke plumes continued to be observed from fires in Kalimantan and southern Sumatra. Under prevailing south-easterly winds, smoke haze was observed drifting towards Singapore.”

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, said NEA.

Smoke haze may continue to drift towards Singapore under the prevailing easterly or south-easterly winds, added NEA.

For the first time since October 2023, air quality in Singapore breached unhealthy levels for the first time on Sept 4. The NEA began 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.

The highest hourly PM2.5 reading to date in 2026 was recorded in the west at 2am on Oct 9, peaking at 171.

The government’s haze task force announced a series of measures on Oct 9 should the PSI exceed 200 and move into the very unhealthy range.

10月12日早上7点左右，金文泰地区出现雾霾天气。

新加坡的雾霾持续了一整夜，所有地区的24小时空气污染指数（PSI）均处于不健康水平。西部地区最高，达到173，中部地区也达到了166。

新加坡国家环境局表示，加里曼丹岛和苏门答腊南部山火产生的烟雾正随东南风飘向新加坡。当地干燥的气候条件可能会使雾霾持续存在。

雾霾工作组于 10 月 9 日宣布，如果 PSI 指数超过 200，将采取相应措施。此前，中部地区的 PSI 指数峰值达到 2026 个百分点，为 192 个百分点；西部地区的 PM2.5 指数峰值达到 171 个百分点。

新加坡——新加坡各地一夜之间仍笼罩在雾霾之中，所有地区的24小时空气污染指数（PSI）均处于不健康范围内。

早上 6 点，西部地区 24 小时污染物标准指数读数最高，为 173，其次是中部地区（166）、东部地区（148）、南部地区（131）和北部地区（126）。

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。

每小时 PM2.5 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）在新加坡的四个地区处于较高水平：中部（110）、东部（99）、西部（97）和南部（76）。

只有北部地区（55）的读数处于正常范围，即将进入高频段。

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。

新加坡国家环境局 (NEA) 在 10 月 12 日晚间发布的每日雾霾预警中预测，新加坡 24 小时空气污染指数 (PSI) 将处于不健康范围。

报告称：“加里曼丹岛和苏门答腊南部地区的火灾持续产生中等至浓重的烟雾。在盛行的东南风影响下，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。

国家环境局补充说，在盛行的东风或东南风的影响下，烟雾可能会继续向新加坡飘去。

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。

2026 年迄今为止最高的 PM2.5 小时读数于 10 月 9 日凌晨 2 点在西部地区记录，峰值达到 171。

政府雾霾工作组于 10 月 9 日宣布了一系列措施，以应对空气污染指数 (PSI) 超过 200 并进入非常不健康范围的情况。
