Is it usually hot in Singapore?


Singapore lies merely 1.5 degrees north of the Equator, basking in warm and humid tropical conditions year-round. The temperature in this bustling city-state seldom strays from a narrow range, typically settling between 25°C and 31°C. This consistent warmth, along with high humidity levels, makes Singapore a hot location by global standards. Visitors won’t experience the four seasons as they might in temperate regions but can enjoy this warm climate at any time of the year.

For those planning to travel, understanding when to visit Singapore can enhance the experience. The cooler months, albeit marginally so, fall around December and January, potentially offering more comfort to tourists unaccustomed to the heat. Conversely, the period from March to June marks the warmer phase within Singapore’s already warm climate, with temperatures occasionally surpassing the average high.

Singapore’s weather also features high levels of precipitation, with rain being a common occurrence, especially during the monsoon season. The likelihood of thunderstorms is significant, with these dramatic weather events happening around 40% of all days. Although there is no true ‘best’ time to visit, travellers might prefer the drier periods between February and April to explore the myriad attractions comfortably.

Climatic Patterns in Singapore

Singapore’s proximity to the equator ensures a warm, humid climate year-round with minimal variation in temperatures. As is characteristic of a tropical climate zone, the country experiences consistent heat and significant rainfall.


Understanding Singapore’s Tropical Climate

Singapore is situated almost on the equator, resulting in a tropical climate. The country’s weather is marked by high temperatures and high humidity, making it feel quite hot throughout the year. Daytime temperatures typically range between 29°C and 31°C with relative humidity levels averaging above 80%. The warm climate in Singapore is constant, with little temperature fluctuations between night and day or across seasons.

Monsoon Seasons and Their Impact

The climate of Singapore is significantly influenced by monsoon seasons. There are two main monsoon seasons: the Northeast Monsoon, occurring from December to early March, and the Southwest Monsoon, from June to September. The Northeast Monsoon brings more consistent rainfall and is considered the wetter period, often referred to as the Wet Season. Conversely, the Southwest Monsoon generally leads to drier conditions, characterised as the Dry Season.

Between these monsoon seasons, inter-monsoon periods occur, which can bring scattered rain showers. Although there exists a relative dry season, it is essential to note that rain can and does occur throughout the year in Singapore due to its equatorial location.

Temperature and Rainfall Trends

Singapore’s climate is characterised by consistent high temperatures and significant rainfall throughout the year. The patterns of heat and precipitation are influenced by its equatorial location.

Average Temperatures Throughout the Year

Singapore experiences a uniform temperature range owing to its position near the equator. Average temperatures hover around 31°C during the day, falling to about 23°C at night. The warmest period typically extends from March to June, with May often being the hottest month of the year. Conversely, the cooler period occurs in December and January, with temperatures only slightly dropping from their yearly norm.


Rainfall Distribution and Variations

Rainfall in Singapore doesn’t fluctuate extensively throughout the year, but certain patterns are observed. The wetter months generally span from September to February, with the rest of the year regarded as the drier period. However, even during these drier months, rain is a common occurrence. Humidity levels are persistently high, contributing to the sensation of warmth. The wettest month is typically December, which sees the highest number of rainy days. Rainfall intensity can vary, with recent trends showing an increase in the frequency of heavy rainfall events.

Adapting to Singapore’s Weather

Singapore’s year-round warm climate with high humidity levels requires specific adaptations in terms of clothing and daily habits for comfort and safety.

What to Wear During Singapore’s Seasons

The weather in Singapore remains warm with the temperature typically ranging from 25°C to 33°C. There is no clear-cut division between seasons, as it is hot throughout the year accentuated by bouts of rain and high humidity. However, some general guidelines can be followed:

  • Dry Season (warmest month): Opt for lightweight clothes such as cotton t-shirts, shorts, and skirts. Clothing should be breathable to help manage perspiration.
  • Rainy Season: Include a waterproof jacket or umbrella due to frequent showers. Despite precipitation, temperatures remain warm, so continue to choose light and comfortable clothing.

Best Practices for Comfort and Safety

To maintain comfort and safety in Singapore’s weather, consider these best practices:

  • Protection from Sunshine: It’s essential to protect oneself from the intense sunshine. Use sunscreen and wear sunglasses. Stay in shade whenever possible, particularly during peak sun hours.
  • Hydration: Drink plenty of water to avoid dehydration due to the heat.
  • Outdoor Safety:
    • Limit outdoor activities during the middle of the day when it is the hottest.
    • Use an umbrella for shade during Sunshine as well as sudden rain.
  • Indoor Considerations:
    • Inside, use fans and air conditioning to create a cool approx 20-24°C environment for relief from the heat.
  • Avoid Hazards and Pollution:
    • Stay informed about thunderstorms and wind conditions.
    • Take precautions during haze episodes, which can be caused by fires in the region. This may involve staying indoors or wearing masks.

Seasonal Events and Activities

Singapore’s year-round warm climate provides a consistent backdrop for a variety of seasonal events and activities that attract both locals and tourists.


Cultural Celebrations and Outdoor Events

Chinese New Year: Celebrated between January and February, it marks Singapore’s most vibrant festival with an explosion of bright colours, joyous festivities, and cultural performances. During this time, streets buzz with markets, and lion dances occur frequently across the city, most notably in Chinatown.

  • Singapore Grand Prix: Held annually, usually in September, this high-profile Formula 1 event electrifies the Marina Bay Street Circuit, drawing racing enthusiasts from all over the world. The event is coupled with entertainment acts and outdoor concerts, making it a festive period for visitors and residents alike.

Tourism and Seasonal Attractions

Great Singapore Sale: Occurring from June to August, this sale season is a highlight for avid shoppers offering attractive discounts throughout the city’s shopping centres and districts.

  • Best Time to Visit for Sightseeing: While Singapore’s weather is consistently warm, the drier months from March to August are ideal for outdoor activities. During this period, tourists can explore attractions like Bukit Timah Nature Reserve without the hindrance of heavy rainfall.

Tourist Note: Tourism peaks during events like the Chinese New Year and the Grand Prix when Singapore’s attractions are most vibrant, though prices may be higher due to the demand.

Environmental Factors Affecting Weather

Singapore’s tropical climate is significantly influenced by a combination of geographical characteristics and regional environmental factors. These elements play pivotal roles in determining the weather patterns, temperature fluctuations, and levels of humidity experienced across the city-state.

Effects of Geography and Urbanisation on Climate

Singapore is an island located at the southern tip of the Malay Peninsula, which exposes it to both maritime influences and the urban heat island effect. Being just one degree north of the equator means it experiences high temperatures year-round, with an annual mean temperature between 26°C and 28°C. The city’s extensive development has led to increased air-conditioning usage, contributing to the urban heat island phenomenon where the city experiences higher temperatures than its surrounding areas.

  • Geography: The island’s geography leads to consistent temperatures and high humidity levels.
  • Urbanisation: Extensive urban development has transformed natural landscapes into a city, where concrete structures absorb and re-radiate heat, elevating local temperatures.

Regional Environmental Influences

Regional environmental conditions also exert a profound effect on Singapore’s climate. The monsoon seasons, lasting from December to early March and from June to September, bring heavy rainfall, sometimes resulting in flash floods. Forest fires in neighbouring regions can cause smoke to drift to Singapore, worsening air quality and visibility. While Singapore is generally sheltered from typhoons, it is still subject to regional sea temperature changes, which can affect local weather conditions and contribute to the intensity of the dry and monsoon periods.

  • Monsoon Seasons: They contribute to significant variations in rainfall.
  • Smoke from Forest Fires: Occasionally affects air quality.
  • Sea Temperature: Alters local weather patterns, especially during monsoon seasons.


Singapore’s Climate

Singapore is situated near the equator, which results in a tropical climate characterised by high humidity and warm temperatures. The city-state experiences consistent climate conditions throughout the year.

Temperature Trends

Observations indicate that average temperatures are rising, both annually and monthly. Warmer nights have become more common, with minimum temperatures following an increasing trend.

Factors Influencing Weather Patterns

Singapore’s geography plays a significant role in its weather phenomena. The urban landscape contributes to higher temperatures during the day. The regional body of water, especially the Singapore Strait to the south, affects local climate conditions.

Climate Projections

Research suggests that increased temperatures and heat events will likely continue due to climate change. This may lead to more pronounced hot periods, particularly during the inter-monsoon times.

Monthly Temperature Range Relative Humidity Range
23 °C to 33 °C 60% to 90%


In summary, Singapore’s climate is consistently tropical and humid, with rising temperatures and an increasing number of hot nights. These conditions are expected to endure and potentially intensify due to ongoing climatic shifts.
