SINGAPORE – Hazy conditions persisted overnight with the western part of Singapore worst hit as the PSI levels there entered the “very unhealthy” range. The hourly PM2.5 readings remained largely in the elevated band across the island. At 6am, the 24-hour Pollutant Standards Index (PSI) in the west stood at 206, after hitting a new high of 207 between 1am and 3am . PSI readings in the rest of the island were in the unhealthy band, led by the central region (185), east (171), south (157) and north (125). Air quality is considered unhealthy when the PSI – a 24-hour rolling average of six key air pollutants – is in the 101-200 range and very unhealthy when it is in the 201-300 range. 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 most parts of the island at 6am: central (89), east (86), west (83) and south (64).

Only the north (52) registered a normal reading.

At 3pm on Oct 14, PM2.5 readings in the western part of Singapore hit the very high range at 288 , the highest reading so far in 2026. PM2.5 scores from 0 to 55 represent normal values, those between 56 and 150 indicate an elevated concentration of fine particles, while readings between 151 and 250 are considered high and scores above 251 are classified as very high. Given that worsening haze situation, the Government has commenced the distribution of masks , said the National Environment Agency (NEA) in a statement on Oct 14. Air-conditioned rooms in more than 300 community clubs (CC), and residents’ committee and residents’ network centres, have also been set up as haze shelters for the public to seek respite in. Residents may contact their nearest CCs regarding their operating hours and location of the haze shelters. Dense smoke haze from fires in Kalimantan was observed to drift towards Singapore, and smoke haze was also observed over Sumatra, said NEA. “The dense smoke haze is expected to continue drifting towards Singapore overnight and tomorrow,” the agency added in its Oct 14 statement. Minister for Sustainability and the Environment Grace Fu said late on Oct 14 that Singapore is “ keeping its options open ” on whether it will take action against errant companies under its Transboundary Haze Pollution Act.

新加坡——昨夜空气中雾霾持续，新加坡西部地区受影响最为严重，空气污染指数（PSI）已进入“非常不健康”级别。全岛PM2.5小时读数大多仍处于较高水平。早上6点，西部地区的24小时空气污染指数（PSI）为206，此前在凌晨1点至3点之间曾达到207的新高。岛上其他地区的PSI读数也处于不健康水平，其中中部地区（185）、东部地区（171）、南部地区（157）和北部地区（125）的数值最高。空气质量指数（PSI）是六种主要空气污染物24小时滚动平均值，当PSI在101至200之间时，空气质量被认为是不健康的；当PSI在201至300之间时，则被认为是非常不健康的。早上 6 点，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）在岛上大部分地区处于较高水平：中部（89）、东部（86）、西部（83）和南部（64）。

只有北部（52）读数正常。

10月14日下午3点，新加坡西部地区的PM2.5浓度达到288，创下2026年至今的最高值，属于极高浓度范围。PM2.5浓度0至55为正常值，56至150表示细颗粒物浓度升高，151至250为高浓度，251以上为极高浓度。鉴于雾霾情况日益恶化，国家环境局（NEA）在10月14日的一份声明中表示，政府已开始分发口罩。此外，政府还在300多个民众俱乐部（CC）、居民委员会和居民网络中心设立了空调房间，作为雾霾避难所，供公众休息。居民可联系就近的民众俱乐部，了解避难所的开放时间和地点。新加坡国家环境局（NEA）表示，加里曼丹岛火灾产生的浓烟正向新加坡方向飘移，苏门答腊岛上空也观测到烟雾。该机构在10月14日的声明中补充道：“预计浓烟将在今晚和明天继续向新加坡方向飘移。”新加坡永续发展及环境部长傅海燕于10月14日晚间表示，新加坡将“保留所有选项”，以决定是否根据《跨境烟霾污染法》对违规企业采取行动。
