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

Singapore is set to experience wet and breezy conditions over the coming days as the Northeast Monsoon continues into the second half of March 2025.

According to the National Environment Agency (NEA), a surge of north-easterly winds between 19 and 21 March 2025 may bring periods of moderate to heavy rainfall, along with gusty winds and cooler temperatures. This would be Singapore third monsoon surge in 2025.


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.

During this monsoon surge, temperatures could dip to around 22 degrees Celsius, making it one of the cooler periods of the season. Once the surge subsides, temperatures are expected to range between 24 and 34 degrees Celsius on most days. Aside from the monsoon surge, short but intense thunderstorms are forecast in the afternoons for the remainder of the month.


With wetter conditions ahead, those with outdoor plans should be prepared for sudden showers. Keep an umbrella or raincoat handy, and for those unaccustomed to Singapore’s cooler days, this might be the perfect time to bring out that rarely used jacket.
