Climate overview
Singapore lies just 137 km north of the equator, and its climate is tropical rainforest (Af): hot, humid and wet all year. There are no real seasons in the temperate sense — average highs stay between 30°C and 32°C in every month, and lows rarely fall below 23°C.
Annual rainfall is high at about 2,340 mm. Instead of summer and winter, Singapore's year is shaped by two monsoons: the wetter Northeast Monsoon from December to early March and the Southwest Monsoon from June to September, with inter-monsoon periods between them that bring afternoon thunderstorms.
Köppen classification: Af — tropical rainforest
Singapore through the seasons
Northeast Monsoon
December – early MarchDecember and January are the wettest months, with long periods of rain and the occasional 'monsoon surge' bringing cooler, breezy weather. The later part of this monsoon, in February, is often relatively dry and sunny.
Inter-monsoon
April – MayWinds are light and variable, and afternoon and evening thunderstorms are common. This is also the hottest part of the year, with highs around 32°C and very humid air.
Southwest Monsoon
June – SeptemberThis period is somewhat drier. Early-morning squalls, called 'Sumatra squalls', can sweep in from the west with strong gusts and heavy rain. Haze from regional fires can occasionally affect air quality in some years.
Inter-monsoon
October – NovemberThunderstorms return in the afternoons and evenings, and rainfall rises toward the Northeast Monsoon. November is one of the wettest months of the year.
What makes Singapore's weather distinctive
Rain in Singapore usually comes as short, heavy thunderstorms rather than all-day rain. A storm can drop a lot of water in an hour, then clear to sunshine. The city is well prepared, with covered walkways, efficient drainage and air-conditioned indoor spaces.
Humidity is the constant. Relative humidity averages 80–85%, making 31°C feel closer to 37–40°C. Lightning is very frequent too: Singapore has one of the highest rates of lightning activity in the world.
Best time to visit Singapore
Singapore can be visited year-round, but February to April is generally the driest and sunniest period. If you prefer to avoid the heaviest rain, skip December and January. Whatever the month, plan outdoor activities for morning and keep an indoor alternative ready for afternoon storms.
What to pack
- Light, breathable clothing in natural fabrics
- A compact umbrella — useful for both rain and sun
- A light layer for strong indoor air-conditioning
- Sunscreen, sunglasses and insect repellent
- Sandals or quick-drying shoes
