SINGAPORE – Singaporeans may get some respite from the haze on Oct 26, as “good to moderate” air quality is expected across the island.

In its daily haze advisory on the evening of Oct 25, the National Environment Agency (NEA) said the PSI is forecast to be in the range of 70 to 100.

Air quality is considered good to moderate when the PSI – a 24-hour rolling average of six key air pollutants – is in the range of zero to 100, and unhealthy when it is in the range of 101 to 200.

NEA said that showers are expected over Singapore and nearby areas on Oct 26.

“With winds expected to blow from the south-west or west, the likelihood of smoke haze affecting Singapore may be reduced,” it said.

It added that this is expected to continue on Oct 27 and 28, as showers over Singapore and the vicinity should lead to an improvement in the haze situation.

The hourly PM2.5 readings returned to normal across all five regions in Singapore on the morning of Oct 25, while the 24-hour PSI levels showed a more gradual decrease.

While smoke haze was observed over Kalimantan, it did not drift towards Singapore, said NEA.

At 7pm, PSI readings were in the “good to moderate” range in four parts of Singapore – the north (94), south (91), east (99), and central (97) regions.

The reading in the west of the island was still in the unhealthy band, at 107.

Meanwhile, the PM2.5 readings ranged between 22 and 31, within the “normal” band.

PM2.5 readings are gauged hourly and reflect the current air quality. Scores from zero to 55 represent normal values, and those between 56 and 150 indicate an elevated concentration of fine particles.

预计新加坡及其周边地区将有阵雨，风向预计为西南风或西风。

新加坡——10月26日，新加坡人或许能暂时摆脱雾霾，预计全岛空气质量将达到“良好至中等”水平。

国家环境局 (NEA) 在 10 月 25 日晚间发布的每日雾霾预警中表示，预计 PSI 指数将在 70 至 100 之间。

当 PSI（六种主要空气污染物的 24 小时滚动平均值）在 0 到 100 之间时，空气质量被认为是良好到中等；当 PSI 在 101 到 200 之间时，空气质量被认为是不健康的。

新加坡国家环境局表示，10月26日新加坡及周边地区预计将有阵雨。

“预计风向将来自西南或西，因此烟雾影响新加坡的可能性可能会降低，”声明称。

报告还指出，预计10月27日和28日新加坡及其周边地区将迎来降雨，届时雾霾情况有望得到改善，因此这种情况预计将持续。

10 月 25 日上午，新加坡所有五个地区的 PM2.5 小时读数均恢复正常，而 24 小时 PSI 水平则呈现更缓慢的下降趋势。

新加坡国家环境局表示，虽然在加里曼丹上空观测到了烟雾，但烟雾并未飘向新加坡。

晚上 7 点，新加坡四个地区的空气污染指数 (PSI) 读数处于“良好至中等”范围——北部 (94)、南部 (91)、东部 (99) 和中部 (97) 地区。

岛屿西部地区的读数仍然处于不健康范围内，为 107。

与此同时，PM2.5读数在22至31之间，处于“正常”范围内。

PM2.5读数每小时测量一次，反映当前的空气质量。0到55之间的数值代表正常值，56到150之间的数值则表示细颗粒物浓度升高。
