Residents of Singapore are advised to prepare for continued wet weather through the remainder of December. The Meteorological Service Singapore indicated on December 16th that thundery showers are expected on most days, particularly in the afternoons and potentially extending into the evenings.
Rainfall and Temperatures
Showers are anticipated to be widespread and, on occasion, heavy. While total rainfall for the latter half of December is currently forecast to be near average across most of the island, the first two weeks of the month saw above-average rainfall in many areas. Jurong Pier, for example, experienced rainfall 175 percent above the usual amount, while MacRitchie Reservoir saw rainfall 7 percent below average.
Despite the increased rainfall, daily maximum temperatures are expected to remain relatively high, ranging between 32 and 34 degrees Celsius on most days. The highest temperature recorded thus far was 34.5 degrees Celsius at Newton on December 5th.
Warnings and Conditions at Sea
The National Environment Agency issued heavy rain warnings on seven days during the first half of December. Flash flood warnings were issued on six days, and flash floods were reported in areas including Kembangan and East Coast Road, according to national water agency PUB.
The Maritime and Port Authority of Singapore (MPA) has advised those at sea to remain vigilant, as the current north-east monsoon conditions – characterized by winds from the north-west or north-east – are expected to persist until March 2026. These conditions may bring stronger winds, choppier seas, and continued moderate to heavy rainfall.
