Good news for those who love the cooler air — this is likely to continue in the first half of December. This will take the form of thundery showers that will come about on most afternoons.
The Northeast Monsoon is expected to become established over Singapore and the surrounding region during the coming fortnight, with the winds strengthening and blowing mostly from the northwest and northeast.
Wet weather in Dec may extend into the night
In a weather advisory on Friday (1 Dec), the Meteorological Service Singapore (MSS) said the current wet weather will likely continue into December.
On most afternoons this month, Singaporeans can expect thundery showers — so do bring an umbrella if you’re out and about.
While the rain will typically ease up at night, this won’t be the case sometimes.
Dec wet weather due to Northeast Monsoon
The increased rainfall will be caused by the Northeast Monsoon, MSS said.
It’s expected to “become established” over Singapore and the surrounding region in the next two weeks.
This means the winds, which will blow mostly from the northwest and northeast, will strengthen considerably. As a result, the total rainfall for the first fortnight of December will be above average over most parts of the island.
Maximum temperature of 34°C on a few days
Despite the higher rainfall, the daily maximum temperature won’t drop too much.
It’s expected to hit around 34°C on a few days, despite the persistent thundery showers.
The daily temperature on most days should be between 24°C and 33°C.
Above-average rainfall in November
As you might know, November was a wet month, with thundery showers over parts of the island in the afternoon on most days. This is thanks to the monsoon rain band that was located over equatorial Southeast Asia in the second half of the month.
Most parts of Singapore saw above-average rainfall during this period, with Ulu Pandan recording 119% above average. Admiralty was the driest region, with rainfall that was 17% below average. Particularly, 21 Nov saw the highest rainfall recorded for the fortnight in Bedok, with a daily total rainfall of 128.8mm.
The temperature, however, was still fairly warm, with the daily maximum above 33°C on most days.
Clementi recorded the hottest temperature of the period on 17 Nov, with a scorching daily maximum of 35.3°C.
As the rainy season is well and truly upon us, let’s enjoy it while it lasts.
Conclusion
In conclusion, Singaporeans can anticipate a continuation of the wet weather into December, with thundery showers being a common occurrence. The influence of the Northeast Monsoon will bring about increased rainfall, particularly in the first fortnight of the month. Despite the rain, temperatures are expected to remain relatively warm, reaching up to 34°C on a few days. Reflecting on the above-average rainfall in November, it’s evident that the rainy season is in full swing. So, let’s embrace the unique experience of the wet season and make the most of it.
