Oct. 2025 weather forecast: More rain in S'pore soon

Looks like sweater weather is here for the next two weeks.

Thundery showers are expected over parts of the island in the late morning and afternoon on most days, said the Meteorological Service Singapore on Oct. 1.

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

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

The daily maximum temperatures are likely to range between 32°C and 34°C on most days and slightly exceed 34°C on a few days.
