SINGAPORE — The second half of July is set to sizzle, with the Meteorological Service Singapore (MSS) forecasting fewer rainy days and more warm, humid nights. Daily maximum temperatures are expected to climb above 34°C on several days, especially in southern and eastern regions.
While the skies will be mostly fair, residents should still brace for short-duration thundery showers in the late mornings and afternoons. Sumatra squalls may also sweep in with gusty winds before dawn on one or two days.
Humidity remains high, especially in southern and eastern areas, with nighttime lows around 28°C.
The first half of July saw frequent showers due to southwest monsoon winds. On 9 July, Sentosa recorded a whopping 87.6mm of rainfall, the highest for the fortnight. Pulau Ubin hit a high of 34.2°C on 6 July, while Clementi saw rainfall 102 per cent above average.
Nighttime temperatures have hovered around 28°C, with warm and sticky conditions persisting across the island. MSS advises residents to stay hydrated and monitor weather updates via the MSS website, NEA website, or the myENV app.
Singapore, located just north of the equator, experiences a tropical rainforest climate characterised by consistent warmth, high humidity, and abundant rainfall throughout the year. The nation's climate is influenced by its maritime exposure and equatorial location, leading to minimal temperature variation across months.
Singapore's climate is defined by two primary monsoon seasons, each bringing distinct weather patterns:
Northeast Monsoon (December to early March)
Early Phase (December to January): Characterised by monsoon surges, leading to widespread moderate to heavy rainfall and occasional wind speeds of 25–35 km/h.
Late Phase (February to early March): Typically drier and windier, with reduced rainfall.
Southwest Monsoon (June to September):
Dominated by southeasterly to southerly winds.
Frequent "Sumatra squalls" occur during the pre-dawn and morning hours, bringing gusty winds and short-duration thundery showers.
Between these monsoons are inter-monsoon periods (April to May and October to November), marked by light and variable winds, intense afternoon thunderstorms, and higher temperatures.
Rainfall in Singapore is abundant and well-distributed throughout the year, with no distinct dry season. The average annual rainfall is approximately 2,340 mm. However, rainfall can vary regionally; the western parts often receive more rain than the eastern areas due to the rain shadow effect.
Temperatures in Singapore are consistently warm:
Daytime highs: Typically range between 31°C and 33°C.
Nighttime lows: Generally fall between 24°C and 26°C.
Record highs: The highest recorded temperature is 37.0°C, observed in April 1983 and May 2023.
Record lows: The lowest recorded temperature is 19.4°C, noted in January 1934.
Relative humidity in Singapore is high year-round, often exceeding 90 per cent in the early morning and dropping to around 60 per cent in the mid-afternoon on dry days. During periods of rain, humidity can reach 100 per cent.
Singapore receives an average of 1,800 to 2,000 hours of sunshine annually. Despite its tropical location, the country experiences significant cloud cover, especially during the monsoon seasons, which can limit sunshine duration.
