Hazy conditions may hit S'pore over the next 2 weeks amid continued dry weather

Hazy conditions may be expected in Singapore over the next two weeks as dry weather is forecast to persist across the surrounding region into the first fortnight of September 2026, said the Meteorological Service Singapore (MSS).

Increase in smoke haze in the region

In its fortnightly weather advisory issued on Sep. 1, MSS said prevailing dry conditions have led to an escalation in hotspot activity and smoke haze in the region.

Dense smoke haze was observed over southern and central Sumatra, as well as various parts of Kalimantan, on most days since around Aug. 21.

While sporadic showers may occur during the second week of this month, dry conditions are expected to persist over most of the surrounding region throughout the fortnight.

Under prevailing southeasterly or southwesterly winds, Singapore could experience hazy conditions should the fires intensify, said MSS.

The National Environment Agency (NEA) will continue to monitor the situation closely and provide updates if conditions change.

Should Singapore's 24-hour Pollutant Standards Index (PSI) enter the Unhealthy range (101-200), NEA will issue daily haze advisories.

Fair conditions expected on most days

Fair and occasionally windy conditions are expected on most days in Singapore, particularly during the first week of September.

Localised short-duration thundery showers may occur over parts of the island in the late morning and afternoon on a few days.

Total rainfall for the first fortnight of September is forecast to be below average over most parts of Singapore.

Daily maximum temperatures are expected to range between 33°C and 35°C on most days, and could exceed 35°C on a few days.

Nights are also expected to remain warm and humid, with minimum temperatures staying above 27°C on most nights.

Dry conditions in late August

The last two weeks of August 2026 were also marked by dry conditions, with fair weather prevailing on most days, as south-west monsoon conditions continued over Singapore and the surrounding region.

There were short thundery showers over parts of the island on some days, while moderate to heavy thundery showers also affected the eastern, southern and central parts of Singapore in the early morning of Aug. 30.

The highest daily total rainfall of 53.8mm during the second fortnight of August was recorded around Telok Blangah that day.

The period was also warm, with daily maximum temperatures exceeding 34°C on most days.

The highest daily maximum temperature of 35.5°C was recorded in Seletar on Aug. 25.

Minimum temperatures remained above 27°C on several nights.

The island also recorded "well below average rainfall" during the second fortnight of August, MSS said.

Rainfall around Admiralty was about 99 per cent below average during the period.
