Haze expected to ease with onset of inter-monsoon; thundery showers on most days in first half of November

Residents in Singapore can look forward to more respite from the haze and heat in the first two weeks of November.

The Meteorological Service Singapore (MSS) said in its fortnightly weather update on Thursday (Oct 29) that moderate to heavy thundery showers are expected over parts of the island on most days, with the showers extending into the evening on a few days.

With the onset of the inter-monsoon period, winds will shift to become light and variable, thereby reducing the risk of smoke haze being transported from fires towards Singapore.

"Together with wetter conditions over Singapore and the nearby areas, the smoke haze situation for Singapore is expected to improve," the weatherman said.

Total rainfall over the first fortnight of November is expected to be slightly above its long-term average over most parts of the island.

During this period, daily maximum temperatures are expected to range between 33 and 35 deg C, although they could slightly exceed 35 deg C on a few days.

Hot and hazy second half of October

Looking back at the weather in the second half of October, MSS said that with winds blowing mostly from the south-west or south-east, smoke haze was transported to Singapore.

Air quality reached the unhealthy levels for seven days, and was in the very unhealthy levels for three days between Oct 16 and 28.

On several days during the second fortnight of October, localised short-duration thundery showers fell over parts of the island.

There were also a few days on which widespread moderate to heavy thundery showers affected Singapore.

The highest rainfall of 81mm was recorded at Tuas South on Oct 21.

Daily maximum temperatures exceeded 34 deg C on most days, with the highest daily maximum temperature of 36.1 deg C recorded at Woodlands on Oct 23.

As it stands, the worst hazy days appear to be behind us, for this year.

新加坡居民有望在11月的前两周摆脱雾霾和高温的困扰。

新加坡气象局（MSS）在周四（10月29日）发布的双周天气预报中表示，预计该岛部分地区大部分时间将出现中到大雷阵雨，部分日子阵雨将持续到晚上。

随着季风间歇期的到来，风向将变得微弱且多变，从而降低火灾产生的烟雾被输送到新加坡的风险。

“随着新加坡及周边地区降雨量的增加，新加坡的烟霾情况预计将会好转，”气象员表示。

预计11月上半月该岛大部分地区的总降雨量将略高于长期平均水平。

在此期间，预计每日最高气温将在 33 至 35 摄氏度之间，尽管有几天可能会略微超过 35 摄氏度。

十月下半月炎热多雾

回顾10月下半月的天气，MSS表示，由于风主要从西南或东南方向吹来，烟雾被输送到新加坡。

10 月 16 日至 28 日期间，空气质量连续 7 天达到不健康水平，其中 3 天达到非常不健康水平。

10 月下半月的几天里，岛上部分地区出现了局部短时雷阵雨。

此外，还有几天新加坡大范围出现中到大雨，伴有雷暴雨。

10月21日，大士南区录得最高降雨量81毫米。

大多数日子里，每日最高气温超过 34 摄氏度，其中 10 月 23 日在伍德兰兹记录到的最高每日最高气温为 36.1 摄氏度。

就目前来看，今年最糟糕的雾霾天气似乎已经过去了。
