If you are planning to visit Singapore, it is important to know about the climatic characteristics of the city-state.

In this section, we will discuss the temperature and humidity, monsoon seasons, and Sumatra squalls that affect the climate of Singapore.

Temperature and Humidity

Singapore has a warm and humid climate throughout the year. The average temperature ranges from 23.3°C (73.9°F) to 31.7°C (89.1°F), with high levels of humidity. The humidity levels remain high due to the city-state’s proximity to the equator and its location in a maritime tropical air mass.

Monsoon Seasons

Singapore experiences two monsoon seasons – the Northeast Monsoon and the Southwest Monsoon. The Northeast Monsoon season occurs from December to early March, while the Southwest Monsoon season occurs from June to September. During the monsoon seasons, Singapore experiences heavy rainfall, which can lead to flooding in some areas. The monsoon rainband affects Singapore’s climate and brings in heavy rainfall during these seasons.

Sumatra Squalls

Sumatra squalls are another weather phenomenon that affects Singapore’s climate. These squalls are thunderstorms that develop over the South China Sea and move towards Singapore. They can bring in heavy rain, strong winds, and lightning. Sumatra squalls usually occur during the inter-monsoon periods, which are the transition periods between the monsoon seasons.

Overall, Singapore’s climate is affected by various factors such as La Nina, sea surface temperature, and climate change. However, the climatic characteristics discussed in this section are the most prominent factors that affect the weather in Singapore.

Thundery Showers and Thunderstorms

Thundery showers are a common occurrence in Singapore, particularly during the inter-monsoon periods of April to May and October to November. These showers are usually short-lived and occur in the late afternoon or early evening. Thunderstorms, on the other hand, are less frequent but can be more severe. They are usually associated with low pressure systems and can result in strong winds, lightning, and heavy rain.

Flash Floods and Rainy Days

Singapore experiences occasional flash floods during periods of heavy rain, particularly in low-lying areas. The Meteorological Service Singapore issues flash flood warnings to alert the public to potential flooding. Rainy days, defined as days with more than 0.2mm of rainfall, occur on average about 167 days per year in Singapore. The Changi Climate Station recorded the highest rainfall in a single day on 2 June 2010, with a total of 243.4mm of rainfall.
