Rainfall and Precipitation

Singapore’s climate, characterised by high humidity, witnesses frequent rainfall. Understanding the nuances of these rain showers and heavier rain events is essential for those living in or visiting the region.

Understanding Rain Showers

Singapore experiences a broad variety of rain showers, ranging from light rain to steady light rain throughout the year. Showers can occur at any time but are often brief. Rain showers can begin suddenly and may be intense, yet they might not last long. On some occasions, scattered showers manifest, affecting different parts of the city unevenly.

Heavy Rain Events

The occurrence of heavy rain events is associated significantly with monsoon surges. These periods of intensive rain can lead to substantial precipitation over a short time. While showers early or showers late in the day are typical during certain months, these heavier events are less predictable and can cause disruptions due to their intensity.

Temperature Trends

Singapore’s climate is characterised by uniform temperatures, however, notable fluctuations are present. Daily highs can show slight variations, influenced predominantly by seasonal changes rather than drastic shifts. Consistent heat combined with high humidity defines the atmospheric moisture content, impacting the perceived temperature.

Daily Highs and Lows

Singapore experiences minimal variation in daily high and low temperatures. The temperature typically ranges from 25°C (77°F) at night to around 31°C (88°F) during the day. Slight deviations occur with cooler nights in December and January, while the period from March to June brings slightly warmer temperatures.

Humidity and Heat

The heat in Singapore is accentuated by high humidity levels, which can range from 70% to 80% during the day. This persistent humid climate often results in a sensation of steady, oppressive heat and may lead to scattered showers, contributing to the general warmth.

  • Average Daytime Humidity: 80%
  • Average Nighttime Humidity: 70%

The moisture in the air often traps the heat, giving rise to a consistent hot environment, frequently described as a steady light blanket enveloping the city-state.

UV Index Insights

In Singapore, the UV Index serves as a critical indicator of ultraviolet radiation levels, which can have significant health implications.

Peak UV Times

The UV Index in Singapore tends to reach the highest points between 11 am and 3 pm. During this period, especially on days with clear skies, the levels often climb to ‘Very High’ or ‘Extreme’. These peak UV levels are a regular occurrence and call for heightened sun protection measures. It is reported that the UV Index can be close to zero at night and varies according to weather conditions, such as rain or cloud cover.


Protection Strategies

When the UV Index forecasts ‘High’ to ‘Extreme’ levels, Singaporeans are advised to adopt several protection strategies. These include:

  • Wearing protective clothing: Long-sleeved shirts, trousers, and broad-brimmed hats can shield the skin.
  • Utilising sunscreen: A sunscreen with a high SPF should be applied regularly, especially during peak UV times.
  • Seeking shade: It is advisable to stay indoors or under cover during midday hours when the UV rays are strongest.
  • Using sunglasses: Eyewear that blocks UV rays helps protect eyes from potential damage.

Understanding the UV Index and practising these strategies can help mitigate the harmful effects of UV radiation in Singapore.

Storms and Thunderstorms

Singapore is susceptible to thunderstorms due to its tropical climate. Thunderstorms in the region are common and can bring about heavy rainfall, lightning, and at times gusty winds.

Thunderstorms Forecasting

Scattered Thunderstorms and Thunderstorms Likely are terms often used in weather forecasts for Singapore. These forecasts indicate that storms could appear sporadically or are anticipated with a high degree of certainty. Meteorological Service Singapore provides lightning alerts, signifying the presence of cloud-to-cloud and cloud-to-ground lightning, which is commonly associated with thunderstorms. The forecast for thundery showers connotes an impending risk of lightning, usually striking within 6km of a location.

Safety Measures During Storms

During thunderstorms, safety measures are vital. It is advised to seek shelter immediately when you hear thunder to avoid the risk of lightning strike. Here is a simple list of precautions to take:
