Singapore residents can expect more wet and humid weather in the second half of May, with thundery showers forecast to occur on most afternoons across various parts of the island.
According to the Meteorological Service Singapore (MSS), the showers are expected to continue through the remainder of the month, with some extending into the evening hours.
Despite the increased rainfall, Singapore is still likely to experience hot afternoons on certain days, with temperatures potentially climbing as high as 35°C during warmer periods.
The latest weather advisory comes as several areas across Singapore recently experienced intense downpours and flash floods following heavy rainfall earlier this month.
Sumatra Squalls Expected To Bring Heavy Rain And Gusty Winds
MSS said short-duration thundery showers are likely to develop on most afternoons in the coming weeks due to prevailing weather conditions in the region.
In addition, some mornings and pre-dawn hours may see widespread thunderstorms accompanied by strong winds caused by Sumatra squalls.
These weather systems commonly affect Singapore during the Southwest Monsoon season and can lead to sudden heavy rain, reduced visibility and cooler temperatures for brief periods.
Authorities said overall rainfall for the second half of May is expected to remain close to the island’s long-term average levels.
Residents commuting during peak hours are advised to carry umbrellas and stay updated on weather alerts, especially with flash floods occasionally occurring during intense storms.
Some Areas Already Recorded Extremely High Rainfall
During the first half of May, many parts of Singapore experienced above-average rainfall levels.
The area around Paya Lebar reportedly recorded rainfall totals nearly 189 per cent higher than historical averages for the same period.
One of the heaviest rain events occurred on May 8, when regional wind convergence triggered widespread heavy showers across the island.
Tampines recorded the highest daily rainfall during that period, with 114.6mm of rain measured in a single day.
The intense downpour also caused temporary flash floods in several locations, including parts of Mountbatten Road, though floodwaters reportedly subsided quickly.
Hot Weather Still Expected Despite Frequent Rain
Even with the increase in rainfall, Singapore’s temperatures have remained relatively high.
MSS said there were six days in the first half of May where maximum temperatures reached at least 34°C.
The hottest day recorded so far this month was on May 2, when Paya Lebar registered a temperature of 35.1°C.
Weather experts noted that while rain showers may provide temporary cooling, high humidity levels can still make conditions feel particularly warm and uncomfortable for many Singaporeans.
With the school holiday period approaching soon, outdoor event organisers and families planning activities are also being encouraged to monitor weather forecasts closely to avoid disruptions caused by sudden thunderstorms.
