Singapore’s Rain Builds to a Thursday Peak, Then Eases

Singapore is heading into a wet spell. Rain turns heavy on Wednesday 28 October, reaches its peak on Thursday 29 October with about 32.7 mm, and begins to ease on Friday 30 October. Over the next three days the city is forecast to collect about 55.9 mm in total.

Singapore weather day by day

Tuesday 27 October is the quiet start. Rain is on the cards but only light, around 2.6 mm, with a high of 26°C (79°F) and a low of 25°C (77°F). Winds reach just 9 km/h, so it will feel calm, though damp.

Wednesday 28 October is when the pattern changes. Around 20.6 mm of rain is expected, and the sky turns to heavy rain. It also gets warmer, with a high of 30°C (86°F) and a low of 24°C (75°F). Winds stay light at 10 km/h.

Thursday 29 October is the worst day. The city should see about 32.7 mm, more than on any other day in this period. Temperatures stay at 30°C (86°F) by day and fall to 23°C (73°F) at night. Winds rise only slightly to 12 km/h, so the story here is rain rather than wind.

Friday 30 October brings an easing. Rain drops to around 14.4 mm, less than half the Thursday amount, though the sky is still heavy rain. The high reaches 31°C (88°F) and the low is 23°C (73°F).

When the rain is worst and when it eases

The build-up is steady. Tuesday gives only a small taste, Wednesday brings a clear step up, and Thursday is the peak. Because the heaviest rain lands on Thursday, that is the day when journeys and outdoor plans are most likely to be disrupted. Friday is still wet, but the amount falls, so it should feel like the spell is loosening its grip.

Rain around Singapore

The city itself looks like the wettest spot nearby, with about 55.9 mm over three days. About 30 km west the total is about 45.2 mm, and about 30 km north it is about 44.5 mm. About 30 km east is a little drier at about 40.3 mm, while about 30 km south is the driest of the places checked at about 28.8 mm. So the heaviest rain is centred on the city, and it is lighter the further south you go.

What it means for people in Singapore

• Plan for Thursday 29 October as the wettest day. If you can, move outdoor events, exercise or errands to another day.
• Allow extra time for travel on Wednesday and Thursday, since heavy rain slows roads and makes walking less pleasant.
• Carry a sturdy umbrella or rain jacket. With temperatures around 30°C (86°F), it will stay warm and humid, so choose light clothing that dries quickly.
• Winds are light, so the main issue is the amount of water falling, not strong breezes.
• Keep an eye on Friday 30 October. Rain eases, but it will not disappear completely.

The bottom line

Expect a damp Tuesday, a properly wet Wednesday, a very wet Thursday and a lighter, but still rainy, Friday. Warm nights and light winds mean the weather will be uncomfortable rather than dangerous in terms of wind, but the steady rainfall is worth planning around, especially on Thursday.
