Singapore is likely to get warmer in May, with daytime temperatures expected to reach 35°C on some days, according to the Meteorological Service Singapore (MSS). 

The daily temperature in the second fortnight of May 2021 is forecast to range between 24°C and 34°C on most days, with warm night-time temperatures of around 28°C expected on some nights.

Short thundery showers on some days

At the same time, short-duration thundery showers are expected over parts of Singapore in the late morning and early afternoon on some days, due to strong daytime heating of land areas.

On some days, the convergence of low-level winds over the Strait of Malacca may trigger the development of Sumatra squalls.

The eastward passage of the squall towards the South China Sea is expected to bring widespread thundery showers and gusty winds over Singapore, between the predawn hours and morning.

Drier and warmer weather expected

In the latter half of the fortnight, the monsoon rain band is expected to shift further north of the Equator, away from Singapore.

As a result, less rainfall is expected during this time over the equatorial Southeast Asia region, including Singapore.

Drier and warmer conditions are expected over Singapore and the surrounding region, and the rainfall for May 2021 is expected to be below average over some parts of the island.
