Thundery showers to continue in S'pore in 1st half of Nov. 2025

Those of you in Singapore might want to move your plans indoors for the next two weeks.

Thundery showers are expected over parts of the island in the afternoon on several days in the first half of November 2025, with the rain extending into the evening on a few of those days, according to a forecast by the Meteorological Service Singapore (MSS) on Oct. 31.

There may also be widespread thundery showers and gusty winds on one or two mornings due to the Sumatra squalls.

The total rainfall for the first half of November 2025 is forecast to be below average over most parts of the island.

The daily maximum temperatures are likely to range between 33°C and 34°C on most days, and reach around 35°C on a few days.

Highest daily temperatures in second half of October recorded in Paya Lebar and Sembawang

In the second half of October, the island saw localised short-duration thundery showers across various parts of the island on some days.

Sumatra squalls also brought widespread thundery showers and gusty winds on a few days.

On Oct. 17, regional convergence of winds brought moderate to heavy thundery showers over the southern and central parts of the island in the afternoon.

The highest rainfall recorded for the period was at Tai Seng that day, which saw a daily total rainfall of 56.8mm.

Later in the month, on Oct. 24, the passage of a Sumatra squall brought widespread thundery showers and gusty winds over Singapore in the night.

The maximum wind gust of 83.2 km/h recorded at Semakau Island that night was the highest wind gust observed in 2025 to date.

Daily maximum temperatures exceeded 34°C on most days in the second half of October.

Both Paya Lebar and Sembawang recorded the highest daily maximum temperatures of 35.7°C on Oct. 30.
