What Is The Rainy Season For Singapore?


Singapore’s climate is classified as tropical rainforest, which results in high humidity and abundant rainfall throughout the year. Despite the relative constancy of temperature and moisture, the region experiences seasonal variations in precipitation. The rainy season aligns with the northeast monsoon, which spans from November to January. During these months, Singapore sees increased rainfall due to the prevailing wind systems that bring moist air over the island, leading to more frequent and intense downpours.

Rainfall during Singapore’s rainy season can significantly impact daily activities as the showers are usually heavy and can last for longer periods compared to other times of the year. The average rainfall peaks around December, with wet conditions persisting into the early part of the year. Travellers planning to visit Singapore should anticipate these weather patterns, as outdoor activities and transportation can be affected by the rainy season’s downpours.

Understanding Singapore’s tropical climate is essential for residents and visitors alike. The high humidity and warmth create conditions that often lead to short spells of rainfall even outside the designated wet months. However, these are usually transient and less disruptive than the sustained rains brought by the northeast monsoon. The clear distinction between the less rainy and wetter periods helps in planning various aspects of life and leisure in this vibrant city-state.

Understanding Singapore’s Climate

Singapore’s climate is characterised by high humidity and abundant rainfall due to its location near the equator and its exposure to different monsoon seasons.


Equatorial Location and Weather Patterns

Singapore is situated just 137 kilometres north of the Equator. This geographical positioning gifts it with a tropical rainforest climate. The country experiences consistent temperatures year-round, typically ranging from 28°C to 31°C. Weather conditions are generally warm and humid, with humidity levels often exceeding 80%. Rainfall is a frequent occurrence, with thunderstorms being common, especially during the monsoon seasons.

Seasonal Changes and Monsoon Cycles

There are two primary monsoon seasons in Singapore: the Northeast Monsoon, from November to January, and the Southwest Monsoon, from June to September.

  • Northeast Monsoon: This period can bring about heavy, sustained rain, contributing to a higher number of rainy days per month. Despite being the wettest season, February usually records the lowest average rainfall of the Northeast Monsoon, which is around 111 mm.

  • Southwest Monsoon: Characterised by lighter, less frequent rain showers, this period is not as wet as the Northeast Monsoon. Rainfall during this time is more sporadic, and dry spells are more common.

The transition months between these monsoon seasons are typically April, May and October. They usually experience less rain compared to monsoon periods, but occasional thunderstorms still occur.

Rainy Season in Singapore

The Rainy Season in Singapore typically spans from November to January, characterised by elevated precipitation levels and the prevalence of thunderstorms.

Typical Duration and Monthly Variations

Singapore experiences its monsoon season starting in November and peaking through December and January. February usually sees a tapering off of the heavy rainfall, although sporadic showers can still occur.

  • November: Transition to wetter conditions begins
  • December: Peak of the Rainy Season
  • January: High rainfall persists
  • February: Gradual decrease in rainfall

Rainfall Patterns and Temperature Averages

During the Rainy Season, the average monthly rainfall is higher compared to other months of the year. The weather during this period is defined by regular showers and frequent thunderstorms, particularly in the afternoon and early evening.

  • Rainfall: Intense during November to January, easing off by February
  • Temperature: Remains warm, averaging around 27°C (81°F)

The increased precipitation provides relief following the warmer and more humid periods experienced leading up to the Rainy Season. It is important for visitors to be prepared for sudden showers and the possibility of thunderstorms during this time.

Travel Considerations During the Rainy Season

When planning a visit to Singapore during the rainy season, travellers should consider the timing of their trip, the impact of weather on activities, and variations in hotel prices and tourist traffic.

Best Time to Visit

The rainy season in Singapore typically spans from November to January, coinciding with the Northeast Monsoon. Travellers looking to experience outdoor festivities like the Mid-Autumn Festival or National Day should schedule their visits outside these months. However, cultural celebrations such as Chinese New Year, Hari Raya Puasa, and Deepavali can be enjoyed even during the rainy season, as many events are held indoors.

Impact on Outdoor Activities and Events

Rain, often occurring in heavy afternoon showers, can affect outdoor activities and events. Visitors should pack umbrellas and raincoats to adapt to sudden changes in weather. While the Singapore Food Festival and outdoor celebrations like Hari Raya Aidilfitri may be less predictable, the country’s extensive network of covered walkways and shopping malls ensures that there is plenty to enjoy, rain or shine.


Hotel Prices and Tourist Traffic

Hotel prices in Singapore may fluctuate depending on the season. During the rainy season, one might find more competitive rates, due to a slight dip in tourist traffic. Nonetheless, significant events like Chinese New Year and the Hungry Ghost Festival may cause temporary surges in prices, so it is wise to book in advance to secure the best deals.

Cultural and Recreational Activities During Rainy Days

When the rain pours in Singapore, the cultural scene thrives, and entertainment options remain plentiful. From sheltered complexes to vibrant indoor celebrations, the city offers a host of experiences, ensuring that soggy weather does not dampen the spirits of locals and tourists alike.

Indoor Entertainment and Shopping

In the event of rain, Singapore’s shopping malls and entertainment centres offer respite with a diverse array of activities. Orchard Road stands out as a premier shopping destination, housing numerous malls where one can shop for fashion, electronics, and souvenirs. During the rainy season, the Great Singapore Sale often coincides, making indoor shopping a popular rainy day activity with tempting discounts and deals.

Entertainment options extend to the various museums around the city, such as the National Museum of Singapore and the ArtScience Museum. These institutions provide intriguing exhibits that are as educational as they are entertaining.

Festivals and Celebrations

Singapore’s calendar is marked by numerous festivals, many of which are celebrated indoors or offer rainproof festivities. For example, the Singapore Food Festival showcases the island’s rich culinary heritage and often features indoor venues where visitors can savour local dishes away from the rain. Similarly, cultural celebrations like the Mid-Autumn Festival provide an opportunity to enjoy displays of lanterns and taste mooncakes in sheltered areas like shopping centres.


Despite the wet season, major events such as the Singapore Grand Prix (Formula One) proceed, with the city’s infrastructure equipped to manage rainfall during the event, enabling spectators to enjoy the races with minimal disruption from the weather.

Gastronomic Experiences

Food is an essential aspect of Singapore’s culture, and the rainy season is no exception for food enthusiasts. Popular food precincts like Chinatown, Clarke Quay, and Little India offer covered areas where visitors can indulge in a diverse range of dining options. From steaming bowls of laksa to aromatic Indian curries, these enclaves serve as gastronomic havens even on the dampest days.

Additionally, the sheltered Gardens by the Bay houses dining establishments within its conservatories, providing guests with the dual experience of enjoying lush greenery and delicious food without having to brave the rain.

Practical Tips for Managing Singapore’s Rainy Season

Visitors and residents can manage Singapore’s rainy season effectively with the right preparation in terms of clothing and personal care.

Appropriate Clothing and Gear

Clothing: Wearing lightweight and breathable fabrics is advisable because of the high humidity, even during rainy days. These materials allow the skin to breathe, reducing discomfort from perspiration. A light raincoat or a waterproof jacket can be invaluable for sudden downpours.


  • Umbrellas: Always carry a compact, durable umbrella that can withstand gusty wind conditions.
  • Footwear: Opt for waterproof or quick-drying shoes to navigate puddles and wet paths comfortably.

Health and Comfort Considerations

Indoor Humidity: Utilise air conditioning and dehumidifiers indoors to maintain a comfortable humidity level. This can mitigate the clamminess associated with the season and protect against mould growth in homes.

Hydration: Despite the cooler, rainy weather, staying hydrated remains essential. Regular water intake aids in maintaining optimal health amidst the humid conditions.
