TEMPO.CO, Jakarta - As October begins, Singaporeans can expect a noticeably wetter start to the month, according to the latest advisory from the Meteorological Service Singapore (MSS).
The shift in weather patterns marks the onset of inter-monsoon conditions, which typically bring increased rainfall, variable winds, and heightened thunderstorm activity across the city-state.
Weather Forecast in Singapore for the First Fortnight of October
In its October 1 update, MSS highlighted that the first half of the month will be characterized by light and fluctuating winds, creating favorable conditions for thundery showers.
These showers are anticipated to occur mostly during the late mornings and afternoons, though a few mornings may also see wet weather. The agency added that lightning activity is expected to be higher than usual during this transitional period, raising the likelihood of intense downpours.
The departure of the south-west monsoon will also pave the way for more frequent showers, with the possibility of Sumatra squalls sweeping across the island. Such squalls, which are fast-moving thunderstorm lines that develop over Sumatra and move eastward toward Singapore, could bring sudden gusty winds in addition to heavy rainfall on one or two mornings.
Despite the wetter conditions, temperatures will remain relatively warm. The daily maximum temperature is expected to range from 32°C to 34°C, with a few days exceeding 34°C.
Overall, rainfall levels for the first fortnight of October are projected to be near the island-wide average, bringing a mix of wet spells and humid heat for residents.
Weather Review in the Second Half of September
The latter half of September 2025 in Singapore was marked by localized, short-lived thundery showers across much of the island, consistent with the ongoing Southwest Monsoon conditions.
Despite the frequent afternoon downpours, overall rainfall levels remained lower than average for the month.
On September 28, Pasir Ris recorded the highest daily rainfall total at 59.4 mm, as regional wind convergence triggered moderate to heavy showers in several areas during the afternoon and evening.
However, these bursts of rain were unevenly distributed, with some regions receiving significantly less precipitation.
Warm conditions also persisted throughout the period, with most days seeing daily maximum temperatures above 33°C.
Pulau Ubin and Admiralty recorded the highest temperatures, both peaking at 34.6°C on September 23 and September 27, respectively.
By the end of the month, September closed with a below-average rainfall tally, most notably in Jurong West, where precipitation levels fell about 94 percent below the long-term average, underscoring the variability of weather across the island.
Singapore’s Rainfall and Temperature at a Glance
Like other Southeast Asia countries, Singapore belongs to the cohort of tropical climates. Citing from the Climate Change Knowledge Portal, Singapore experiences copious rainfall and relatively high humidity throughout the year.
The SG team of Yahoo! News added that the country’s rainfall is generally well-distributed, with no distinct dry season. Although the average annual rainfall is 2,340 mm, the western regions receive more rainfall than the eastern regions due to the rain shadow effect.
Singapore experiences consistent warm temperatures, with daytime highs typically ranging between 31°C and 33°C. On the other hand, the country’s nighttime lows can hit from 24°C to 26°C on most days.
