Keep your umbrellas handy for the next two weeks, as rain is expected on most afternoons in the first half of April.
Moderate to heavy thundery showers are expected over parts of Singapore in the afternoon on most days, said the Meteorological Service Singapore (MSS) on April 1.
The showers may extend into the evening on a few of these days.
In addition, Sumatra squalls may bring widespread thundery showers and gusty winds on one or two mornings.
The total rainfall for the first fortnight of April is forecast to be above average over most parts of the island.
Daily maximum temperatures are likely to range between 33 deg C and 34 deg C on most days, and may reach around 35 deg C on a few days.
MSS said that north-east monsoon conditions that have prevailed over the region since mid-November 2024 are expected to gradually weaken and end.
The inter-monsoon period usually lasts till May, and is characterised by light and variable winds and higher lightning activity.
In a review of the weather conditions from March 17 to 31, MSS said the second fortnight of March was very wet, with moderate to heavy thundery showers affecting parts of the island on most days.
On March 19 and 20, a surge of north-easterly winds, or monsoon surge, over the South China Sea brought spells of moderate to heavy showers over Singapore and the surrounding region.
This was the third wet monsoon surge in Singapore in 2025
MSS said the daily total rainfall of 216.8mm recorded in Kallang on March 20 was the highest recorded for the second fortnight of March.
Last month was the wettest March on record at 482.9mm – based on data since 1980 – surpassing the previous record of 451mm set in March 2004.
MSS said the daily maximum temperatures in the second fortnight of March were between 32 deg C and 34 deg C on most days.
During the monsoon surge on March 19 and 20, the daily minimum temperatures ranged from about 22 deg C to 24 deg C, while daily maximum temperatures ranged from about 24 deg C to 28 deg C.
The lowest daily minimum temperature for the second fortnight of March was 21.9 deg C, recorded in Tuas South during the surge on March 20.
Well above average rainfall was received across the island in the second half of March, with Changi registering rainfall that was 570 per cent above average, MSS added.
