Monsoon surge

Meteorological Service Singapore said in a Mar. 17 media advisory that a surge of north-easterly winds, also known as a monsoon surge, is expected to form over the South China Sea between Mar. 19 and 21, 2025.

For Singapore and the surrounding vicinity, the surge could bring windy and cooler conditions with periods of moderate to heavy showers.

While the monsoon surge will usher in aircon weather for a few days, intense rainfall may overwhelm drains and canals temporarily, causing flash floods, warned PUB, Singapore's National Water Agency.

As such, PUB encouraged residents to stay informed by subscribing to the PUB Flood Alerts Telegram channel and adjust their travel plans if needed.
