SINGAPORE – More rain fell over Jan 10 and 11 than Singapore typically receives across the entire month of January.

Changi recorded the highest total amount of rainfall at 255.2mm across the two days, exceeding Singapore’s monthly average rainfall of 222.4mm in January, national water agency PUB said in a statement on Jan 12.

PUB said the prolonged rainy weather caused by the ongoing monsoon surge is expected to persist until Jan 13.

The agency issued several flood risk warnings on Jan 10 and 11 in locations such as Jalan Seaview, which is off Tanjong Katong Road, the junction of Mountbatten Road and Tanjong Katong Road South, as well as Jalan Pokok Serunai.

Heavy rain in these areas resulted in high water levels in drains and canals.

Flooding occurred along a stretch of Jalan Seaview on the evening of Jan 10 because of heavy rain coinciding with a high tide of 2.8m that temporarily overwhelmed the adjacent canal and surrounding roadside drains.

“PUB’s Quick Response Teams were deployed to flood-risk locations, including to Jalan Seaview, to assist residents. They helped to pump water from flooded roads and distributed flood protection devices to residents,” PUB said.

The agency added that it was aware of several videos circulating online which show flooding that occurred in November and December 2024.

“We urge members of the public not to share or post these videos, as they may cause confusion or unnecessary alarm,” it warned.

The public can stay updated on the weather and flash floods through official channels, such as the myENV mobile app and PUB’s Flood Alerts Telegram channel.

Flood safety tips are also available on the PUB website.

SINGAPORE - National water agency PUB has warned of the risk of flash floods, amid torrential rain across the island on March 19.

At 2.45pm, PUB issued a flash flood risk alert for Mountbatten Road/Jalan Seaview.

“Due to heavy rain, please avoid this location for the next one hour”, the agency said.

The National Environment Agency on March 17 said that a monsoon surge was expected in Singapore from March 19 to 21.

This makes it the Republic’s third monsoon surge of 2025, with the previous one occurring from Jan 17 to 19.

The weather phenomenon occurs when cold air moves southwards to the South China Sea, and is blown towards the tropics, bringing with it strong winds and rain.

Monsoon surges typically occur during the earlier phase of the north-east monsoon season, from December to January.

The Republic is currently in the end phase of the monsoon season, which is set to last till end-March.

In late 2024, PUB launched its campaign to encourage the public to be flood-ready, using the mnemonic Flash.

People are advised to follow these tips:

  • Follow PUB flood alerts
  • Learn how to be flood-ready
  • Avoid flooded areas
  • Share PUB flood updates
  • Help others where possible

SINGAPORE - A third monsoon surge brought rain and lowered temperatures to 23.6 deg C at around noon on March 19.

The eastern part of the Republic was covered by rain clouds at around 9.15am, and an hour later, it was raining all over Singapore, according to the National Environment Agency’s (NEA) myENV map.

Heavier rain clouds were observed in central and eastern Singapore at 10.20am, but no floods were reported in the PUB Flood Alerts channel on the Telegram messaging app.

This comes after NEA warned about a monsoon surge from March 19 to 21, which may bring temperatures down to as low as 22 deg C amid periods of moderate to heavy showers over Singapore.

This third surge event so far in 2025 is uncommon, as these surges tend to occur during the earlier phase of the north-east monsoon season – between December and January. Singapore is now in the end phase of the monsoon season, which typically lasts till March.

According to the Meteorological Service Singapore (MSS), the most recent intense wet surge happening late in the season occurred between Feb 28 and March 1 in 2023. This was followed by a weaker surge from March 3 to 4 that year.

A monsoon surge refers to bursts of cold air from the north-east, such as Central Asia, which warms as it sweeps southwards towards the tropics and rolls over the South China Sea. It then picks up moisture, which leads to the formation of dense rain clouds.

This brings widespread increased rainfall, strong winds and cooler weather near the Equator.

As the rain belt shifts from Singapore southwards around February, the north-east monsoon progresses into the second or dry phase, during which a strengthening of winds can be observed.

During such events, Singapore usually experiences windy but fair conditions, MSS said.

On average, Singapore experiences up to four monsoon surges each year, with each event lasting between one and five days.

The rainfall can be prolonged, like it was in the previous surge from Jan 10 to 13. The deluge on Jan 10 and 11 alone exceeded the amount of rain Singapore typically receives in the entire month of January.

Changi recorded the highest total amount of rainfall at 255.2mm over those two days, exceeding nation’s monthly average rainfall of 222.4mm in January.

A security expert warned that other than posing an inconvenience to livelihoods and business operations, periods of prolonged rain and strong winds can also pose a safety risk.

“Prolonged heavy rain and strong winds can disrupt operations and even pose safety hazards – such as flooding and flying debris – if temporary structures like stalls and tents of night markets and Ramadan bazaars, for instance, are not secured properly,” said Mr Bala Selvam, regional security manager of International SOS.

He added that businesses ought to address risks including areas getting waterlogged – something that happens when soil and dirt paths become flooded as a result of soil pores filling up with water instead of air – slippery surfaces and falling debris.

“Installing non-slip mats, clearing pathways and ensuring temporary structures are securely anchored can mitigate hazards.

“Contingency planning should also extend beyond infrastructure. Staff should be trained in emergency response protocols– including evacuation procedures and safety drills – and ensuring preparedness for unexpected surges and weather changes,” he said.


National water agency PUB has said that commuters, besides wielding an umbrella, should adjust their travel plans between March 19 and 21, if needed, and check for flood risks and plan travel routes accordingly.

It also advises moving to higher ground where possible as flood waters may rise suddenly. Residents and businesses in flood-prone areas should install flood barriers – provided by the authorities – when there is a risk of floods occurring.

People should avoid treading through moving water that is above ankle height, as it can lead to slips and accidents. If absolutely necessary, they should use a stick or umbrella to check for open drains and firmness of the ground before taking a step.

Residents and business owners should move essential items to higher ground and avoid touching electrical switches or appliances if they are standing in water.

Drivers of vehicles stranded in flood waters should avoid braking to keep the engine speed higher and constant.

Each flash flood episode tends to last less than an hour in Singapore.

SINGAPORE - National water agency PUB issued a warning on the morning of March 20 about the potential for flash floods as relentless rain continued across the island overnight.

At around 7.40am, PUB issued a flash floods risk alert for the PIE (towards Changi Airport) after TPE.

“Due to heavy rain, please avoid this location for the next 1 hour,” it said in a post on X.

This marks the second consecutive day that PUB has issued a flash flood risk alert.

The incessant rain was the result of a monsoon surge that started on the morning of March 19 and had lowered temperatures to 23.6 deg C at around noon.

This came after NEA warned about a monsoon surge from March 19 to 21, which may bring temperatures down to as low as 22 deg C amid periods of moderate to heavy showers over Singapore.

As of 6.57am on March 20, the mercury dipped to 22.2 deg C in Newton. Singapore’s lowest temperature in 2025 was 21.6 deg C, recorded on Jan 11 in Newton.

The monsoon surge, known for causing widespread and prolonged rain, is unusual since monsoon surges typically occur earlier in the north-east monsoon season, between December and January. Singapore is currently in the late phase of the monsoon season, which usually lasts until around March.

A monsoon surge occurs when bursts of cold air from the north-east, originating from regions like Central Asia, move over the South China Sea, bringing extensive rainfall, strong winds, and cooler temperatures to Singapore. On average, the Republic experiences two to four monsoon surges annually.
