SINGAPORE – Drier conditions are expected in the first half of October, particularly during the first week of the month, with fair and warm conditions on several days.

Total rainfall for the first half of the month is forecast to be below average over most parts of the island, making it drier than the previous two weeks, said the Meteorological Service Singapore in its fortnightly weather advisory on Oct 1.

However, localised thundery showers are still expected over parts of Singapore in the late morning and afternoon on a few days.

Nights may also be humid, with minimum temperatures remaining above 27 deg C.

“South-west monsoon conditions are prevailing over Singapore and the surrounding region, and are expected to continue in the coming fortnight, with winds blowing mainly from the south-east or south-west,” said the Met service.

Air quality back within moderate levels

The 24-hour Pollutant Standards Index (PSI) readings across Singapore was within moderate levels at 4pm on Oct 1, ranging from 59 to 73.

This comes after the central region reached a new peak this haze season early on Sept 29, when air quality across Singapore breached the unhealthy band for the first time in two weeks .

The PSI reading is a 24-hour rolling average of six key air pollutants and is used in planning for outdoor activities the next day.

Air quality is considered unhealthy when the 24-hour PSI is in the range of 101 to 200, during which the National Environment Agency advises the public to at least reduce outdoor activities.

PSI readings of 51 to 100 are considered moderate, while values of zero to 50 are in the “good” range.

新加坡——预计10月上半月天气将较为干燥，尤其是在该月的第一周，其中几天天气晴朗温暖。

新加坡气象局在 10 月 1 日发布的双周天气预报中表示，预计本月上半月岛上大部分地区的总降雨量将低于平均水平，比前两周更加干燥。

不过，未来几天，新加坡部分地区在上午晚些时候和下午仍可能出现局部雷阵雨。

夜间湿度可能较高，最低气温保持在 27 摄氏度以上。

气象部门表示：“新加坡及其周边地区目前盛行西南季风，预计未来两周内仍将持续，风向主要来自东南或西南。”

空气质量已恢复至中等水平

10 月 1 日下午 4 点，新加坡 24 小时污染物标准指数 (PSI) 读数处于中等水平，范围在 59 至 73 之间。

此前，新加坡中部地区的雾霾在 9 月 29 日达到本季雾霾季的新高峰，新加坡全国空气质量两周以来首次突破不健康等级。

PSI读数是六种主要空气污染物的24小时滚动平均值，用于规划第二天的户外活动。

当 24 小时 PSI 值在 101 至 200 之间时，空气质量被认为是不健康的。在此期间，国家环境局建议公众至少减少户外活动。

PSI读数在51到100之间被认为是中等的，而0到50之间的值则属于“良好”范围。
