Singapore Weather

The Weather

Singapore has an equatorial climate, with no distinct seasons. Due to its maritime exposure and proximity to the equator, Singapore has near uniform temperatures, pressure, abundant rainfall and high humidity all-year round. The months of May and June are the hottest, with relatively less rainfall and strong sunshine. The North-east monsoon brings higher rainfall from November through to January, hence lowering temperatures somewhat.

Frequent travellers may be aware that different parts of Southeast Asia experience wet seasons at different times of the year. The table below illustrates this point:

CityWettest Month of the Year
Yangon (Myanmar, 16.8 N, 96.2E)July/August
Kota Bharu (Malaysia, 6.2N, 102.3E )November/December
Singapore (Singapore, 1.3N, 103.8E)December
Jakarta (Indonesia, 6.2S, 106.8E)January/February

Deciding when to travel to a country may be a pain sometimes. Though Singapore is hot and wet all year-round, the following information should give you an inkling of what to expect at different months. 

MonthGeneral Weather Features
January

January can be very wet in some years and dry in others. It all depends on when the Northeast Monsoon transitions into the late (or dry) phase of the monsoon.
Wettest January : 818.6 mm (January 1893)
Driest January : 15.4 mm (January 1997)

Average monthly rainfall is high.
Still at the peak of the Northeast Monsoon, January is windy with winds blowing mainly from the north or northeast.

FebruaryRelatively dry month of the year, generally windy like in Jan
March

Surface wind becomes increasingly light and showers/thunderstorms are more frequent in the later part of the month.

March may be noted for its hot afternoons. The climate-station’s highest temperature of 36.0°C was recorded on 26 March 1998.

Light winds, cloudless skies and more direct solar radiation are some of the contributing factors.

April

Like March, April is a realatively hot month.

Winds are light and variable. There might be the occasional widespread showers with gusty winds in the early mornings.

MayWinds are light. Showers/thunderstorms are common in the afternoons.
June

Southwest monsoon becomes established.

Scattered showers/thunderstorms occur in the afternoon occasionally. Overall, June remains drier than the previous months.

Short periods of hazy conditions may spring up.

JulyRelatively dry month. Very similar to June.
AugustWeather pattern similar to June and July. As the SW monsoon is at its peak, winds of 15-20km/h tend to blow onshore from the island's East Coast.
SeptemberIncreased frequency in afternoon showers.
OctoberOctober marks the beginning of the rainy season at the year's end. Afternoon showers contribute the bulk of the rainfall.
NovemberThe second wettest month of the year. There might be episodes of afternoon thunderstorms extending into the evening.
December

The wettest month of the year. Heavy thunderstorms in the afternoons are common. Coupled with monsoon winds, there might be widespread heavy rain.

The rain may be continuous, stretching for days.

What to wear

Being rather humid with lots of sunshine throughout the year, be sure to dress lightly when outdoors. A simple cotton or dri-absorbent top will suffice. It is advisable to bring along your caps or sunglasses too. Most locals tend to wear shorts with slippers, choosing to dress down for more comfort. It is also important to hydrate yourself more regularly due to the humidity and heat.
