SINGAPORE - Residents in all areas across the island woke up to air quality in the good to moderate range early on Oct 23. At 6am, the PM2.5 readings - a gauge of the current air quality - were 18 in the north, 26 in the south, 27 in the east, 53 in the west and 29 in central - within the normal range. Scores from zero 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. The 25-hour Pollutant Standards Index stood at 68 in the north and south, 71 in the east, 89 in the west and 79 in central. This means all the regions have had air quality in the good to moderate range - when normal activities can be carried out by everyone - for at least 24 hours. The west moved into this ideal category only at 3pm on Oct 22. Since Oct 5, Singapore had been experiencing unhealthy air quality, denoted by 24-hour PSI readings above 101. The 24-hour PSI - a rolling index of six key air pollutants - reflects air quality in Singapore over the past day. When air quality breaches this threshold, people, especially the elderly, children and those with health issues, should start scaling down outdoor activities. However, the National Environment Agency (NEA) has forecast that the air quality could worsen on Oct 23, with PSI levels forecast to range from 101 to 150.

While showers are forecast over Singapore and the surrounding region on Oct 23, dry conditions are expected over the southern parts of Sumatra and Kalimantan, it added.

Under prevailing south-easterly winds, smoke haze may be transported towards Singapore, NEA said.

Smoke haze from Sumatra may also drift towards Singapore on Oct 24 because of south-easterly or southerly winds, but rain should bring relief before clearer conditions return on Oct 25.

新加坡——10月23日清晨，全岛居民醒来时发现空气质量良好至中等。早上6点，PM2.5（衡量当前空气质量的指标）读数分别为：北部18，南部26，东部27，西部53，中部29，均在正常范围内。PM2.5读数0至55代表正常值，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。25小时污染物标准指数（PSI）分别为：北部和南部68，东部71，西部89，中部79。这意味着所有地区的空气质量至少在过去24小时内都处于良好至中等水平，人们可以正常进行各项活动。新加坡西部地区直到10月22日下午3点才进入理想空气质量范围。自10月5日起，新加坡的空气质量一直处于不健康状态，24小时空气污染指数（PSI）读数超过101。24小时PSI是六种主要空气污染物的滚动指数，反映了新加坡过去一天的空气质量。当空气质量超过这一阈值时，人们，尤其是老年人、儿童和有健康问题的人，应该开始减少户外活动。然而，国家环境局（NEA）预测，10月23日空气质量可能会进一步恶化，PSI值预计将在101至150之间。

气象部门补充说，虽然预计10月23日新加坡及其周边地区会有阵雨，但苏门答腊岛和加里曼丹岛南部地区预计将保持干燥天气。

新加坡国家环境局表示，在盛行的东南风作用下，烟雾可能会被输送到新加坡方向。

10 月 24 日，受东南风或南风影响，苏门答腊岛的烟霾可能会飘向新加坡，但降雨应该会带来缓解，之后天气将于 10 月 25 日转晴。
