SINGAPORE – Those heading out in the last two weeks of November should keep their umbrellas handy as thundery showers are expected over parts of Singapore on most afternoons, said the Meteorological Service Singapore (MSS).
In its fortnightly weather advisory on Nov 17, the MSS said that the showers may extend into the evening on a few of these days.
Sumatra squalls may also bring widespread thundery showers and gusty winds on a few mornings during this period.
The total rainfall for the second fortnight of November is forecast to be above average over most parts of the island.
Daily maximum temperatures are likely to range between 32 deg C and 33 deg C on most days but may reach around 34 deg C on a few days.
The north-east monsoon is expected to set in around end-November, bringing with it stronger winds blowing from the cool Northern Hemisphere towards the Equator. The season typically extends to March.
In its review on weather conditions in the first half of November, MSS said that inter-monsoon conditions over the island and the surrounding region brought light and variable winds.
There were thundery showers in the afternoon on most days.
But on a few days, Singapore saw widespread thundery showers and gusty winds because of the Sumatra squalls
On Nov 16, widespread moderate to heavy thundery showers fell over many parts of the island in the late morning and afternoon.
The highest rainfall recorded for the first half of November – 101.8mm – was recorded around Pulau Semakau on that day.
Meanwhile, the daily maximum temperatures during that fortnight were over 33 deg C on most days.
On Nov 1, the highest daily temperature of 36 deg C was recorded in Newton. This was the highest temperature ever recorded in November since temperature records started in 1929.
It exceeded the previous record of 35.8 deg C on Nov 3, 2023, in Newton and on Nov 18, 2019, in Admiralty.
Most parts of Singapore also saw below-average rainfall in the first half of November.
For instance, the area around Jurong registered rainfall of 64 per cent below average, while the area around Changi registered rainfall of 49 per cent above average.
Ahead of the year-end rainy season, national water agency PUB on Nov 17 said that more than 600 water level sensors will be installed islandwide
Other measures in the works include integrating flood alerts on Google Maps and using mobile phone signals to better predict intense rainfall.
