Singapore is bracing for another wet weekend from 17 to 19 January as a second monsoon surge brings windy and cooler conditions, according to the Meteorological Service Singapore (MSS).

Moderate to heavy thundery showers are expected across the island and surrounding areas. Temperatures may drop to around 22°C during the surge, before returning to a range of 24°C to 34°C in subsequent days, MSS reported on Thursday (16 January).

The combination of intense rainfall and seasonal high tides increases the risk of flash floods, particularly in low-lying areas like East Coast Park. The national water agency, PUB, warned that tides could rise to as high as 3.2m during the monsoon surge, potentially causing high water levels in coastal canals.

Record Rainfall and Flood Preparations
Earlier this month, from 10 to 13 January, Singapore experienced record-breaking rainfall. Pulau Tekong recorded 241.8mm of rain on 10 January, more than double the daily average across the country’s 32 weather stations and surpassing the previous record of 238.2mm set in 2011 on Pulau Ubin.

The heavy rain resulted in flash floods, fallen trees, potholes, and delayed flights. Jalan Seaview in Mountbatten faced flash floods as heavy rain coincided with a 2.8m high tide, temporarily overwhelming roadside drains and nearby canals.

PUB’s Measures to Mitigate Flooding
PUB has taken proactive measures to address flood risks. Protective devices and barriers have been distributed to residences and businesses in flood-prone areas. The agency stated that quick response teams will be on standby to manage flooding incidents and support affected communities.

Singaporeans are encouraged to stay updated through the myENV app, PUB’s Flood Alerts Telegram channel, and online resources for flood safety tips.

A Cooler and Wetter January
The ongoing monsoon season has brought unusually low temperatures and strong winds. Newton recorded a drop to 21.6°C earlier this month, marking one of the chilliest days of the season.

As the weather agency monitors the situation closely, residents are urged to remain vigilant, particularly in areas prone to flash floods.
