SINGAPORE: Air quality in western Singapore remained very unhealthy on Sunday (Oct 18), with the 24-hour Pollutant Standards Index (PSI) readings in the other four regions of the country staying in the unhealthy band.

At 7am, the 24-hour PSI reading in the west stood at 228, with readings in the other regions ranging from 129 to 186.

Hourly PM2.5 readings, meanwhile, were elevated across the country, ranging from 79 to 132.

In an advisory on Saturday, the National Environment Agency (NEA) said that the 24-hour PSI is forecast to be in the unhealthy to very unhealthy range for Sunday.

It added that it also observed smoke haze over Sumatra. On Sunday, winds are forecast to shift to blow from the south-southeast or south, which may reduce the transport of smoke haze from Kalimantan to Singapore, said NEA, adding that some smoke haze from Sumatra may still drift towards Singapore. There will also likely be rain over Singapore and the surrounding region. "On Monday and Tuesday, more showers are forecast over Singapore and parts of Kalimantan and winds (are) expected to gradually weaken and blow from the southeast or south," said NEA. This could similarly further decrease the transport of smoke haze from Kalimantan to Singapore, although some smoke haze from Sumatra may drift towards Singapore. Earlier on Saturday morning, NEA warned of a continued risk of severe transboundary haze, with dry conditions expected to persist in parts of the southern ASEAN region over the coming days.

All ActiveSG sports facilities resumed operations on Saturday, following haze-related closures the day before.

However, the unpredictable haze conditions have prompted organisers to cancel or postpone several outdoor events, including the FA Cup football final and third-place play-off scheduled for Saturday.

The Great Eastern Women's Run , originally scheduled for Nov 1, has also been cancelled, while The Purple Parade, an annual event celebrating the abilities and contributions of persons with disabilities, has been postponed to the first half of 2027.

Under the Ministry of Health's (MOH) latest haze advisory, members of the public are advised to refer to 1-hour PM2.5 readings, rather than the 24-hour PSI, when deciding whether to wear a mask for immediate outdoor activities.

MOH said vulnerable individuals, including the elderly, pregnant women and those with chronic heart or lung conditions, should avoid outdoor activities when hourly PM2.5 readings are in the high band of 151 to 250.

Those who need to go outdoors for immediate activities may wear a well-fitting N95 mask or equivalent to reduce their exposure to haze particles.

When PM2.5 readings reach the very high band of 251 and above, healthy individuals should also minimise all outdoor activities. Those who need to venture outdoors may similarly use an N95 mask for protection.

The ministry also cautioned that elderly people, pregnant women and those with severe heart or lung conditions who experience breathing difficulties should consult their doctor before using an N95 mask.

Those who experience discomfort while wearing one should take a break from using it.

Besides N95 masks, KN95, FFP2 and KF94 masks are also effective in reducing exposure to haze particles, MOH said.

上午 8 点，西部地区的 24 小时 PSI 为 228，其他地区的读数在 129 到 186 之间。

新加坡：周日（10 月 18 日），新加坡西部地区的空气质量仍然非常不健康，该国其他四个地区的 24 小时污染物标准指数 (PSI) 读数也处于不健康水平。

早上 7 点，西部地区的 24 小时 PSI 读数为 228，其他地区的读数在 129 到 186 之间。

与此同时，全国各地的 PM2.5 小时读数均有所升高，范围从 79 到 132 不等。

国家环境局（NEA）周六发布公告称，预计周日的24小时空气污染指数（PSI）将处于不健康至非常不健康的范围内。

新加坡国家环境局（NEA）表示，受东南风影响，加里曼丹岛火灾产生的烟雾周六继续向新加坡飘移。NEA还补充说，苏门答腊岛上空也出现了烟雾。

新加坡国家环境局表示，预计周日风向将转为东南偏南或正南风，这可能会减少加里曼丹岛的烟霾向新加坡的输送；同时补充说，苏门答腊岛的一些烟霾可能仍会飘向新加坡。

新加坡及周边地区也可能出现降雨。

新加坡国家环境局表示：“预计周一和周二，新加坡和加里曼丹部分地区将有更多降雨，风力预计将逐渐减弱，并从东南或南部吹来。”

同样，这可能会进一步减少从加里曼丹岛向新加坡输送的烟霾，尽管来自苏门答腊岛的一些烟霾可能会飘向新加坡。

周六上午早些时候，尼泊尔国家环境局 (NEA) 警告称，严重的跨境雾霾风险持续存在，预计未来几天东盟南部部分地区将持续干燥天气。

受雾霾影响，ActiveSG所有体育设施于周六恢复运营，此前一天这些设施因雾霾而关闭。

然而，由于雾霾情况难以预测，组织者不得不取消或推迟多项户外活动，包括原定于周六举行的足总杯足球决赛和季军争夺战。

原定于 11 月 1 日举行的“大东部女子长跑赛”也被取消，而一年一度的“紫色游行”（旨在庆祝残疾人的能力和贡献）则被推迟到 2027 年上半年举行。

根据卫生部最新的雾霾建议，公众在决定是否佩戴口罩进行户外活动时，应参考 1 小时 PM2.5 读数，而不是 24 小时 PSI 值。

卫生部表示，老年人、孕妇以及患有慢性心脏或肺部疾病的人等弱势群体，在PM2.5小时读数处于151至250的高位区间时，应避免户外活动。

那些因紧急情况需要外出的人可以佩戴贴合度良好的 N95 口罩或同等防护等级的口罩，以减少接触雾霾颗粒。

当PM2.5浓度达到251及以上（极高水平）时，健康人群也应尽量减少户外活动。必须外出的人群同样可以佩戴N95口罩进行防护。

该部还提醒，老年人、孕妇以及患有严重心脏或肺部疾病且出现呼吸困难的人，在使用 N95 口罩前应咨询医生。

如果佩戴时感到不适，应暂停使用。

卫生部表示，除了N95口罩外，KN95、FFP2和KF94口罩也能有效减少接触雾霾颗粒。
