Brace for Rainy and Windy Days: Monsoon Surge and Potential Flash Floods in Singapore

As the weekend approaches, the NEA has advised Singaporeans to prepare for a monsoon surge expected to bring rainy and windy conditions from 10 January (Friday) to 13 January 2025 (Monday).

This weather event will bring moderate to heavy thundery showers and cooler, breezy conditions, with minimum daily temperatures possibly dropping to 22°C in some areas.


A monsoon surge refers to a sudden strengthening of winds over the South China Sea, often associated with high-pressure systems from northern Asia. These winds bring cool air masses into the region, leading to widespread rain, stronger gusts, and cooler temperatures. In Singapore, monsoon surges are common during the northeast monsoon season, typically occurring between December and March.

The Public Utilities Board (PUB) has cautioned that there is potential for flash floods during periods of heavy rain. Residents are strongly encouraged to remain vigilant, avoid flood-prone areas, and use resources such as the MyENV app or the PUB Flood Alerts Telegram channel to receive real-time heavy rain updates and flood warnings.
