As
November sets in,
Singapore experiences a distinct shift in weather, marking the onset of the Northeast Monsoon. The highest relative humidity of the year is recorded at 86.4%, while the rainfall increases to a significant 257mm (10.12"). Such meteorological changes underscore the movement towards wetter and more humid conditions compared to preceding months. Despite the damp conditions, the city continues to bask in warmth, creating an authentic tropical rainforest-like atmosphere. These weather dynamics continue to provide a distinct charm to this cosmopolitan city-state.
Temperature
At the onset of November, Singapore records an average high-temperature of a still tropical 30.6°C (87.1°F), showing little deviation from the preceding month. Singapore cools down to an average low-temperature of 23.7°C (74.7°F) throughout the month of November.
Heat index
In November, the heat index is computed to be a blisteringly hot 42°C (107.6°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
Humidity
In November, the average relative humidity is 86.4%.
Rainfall
In Singapore, during November, the rain falls for 19 days and regularly aggregates up to 257mm (10.12") of precipitation. Throughout the year, in Singapore, there are 178 rainfall days, and 2343mm (92.24") of precipitation is accumulated.
Sea temperature
In November, the average sea temperature in Singapore is 29.8°C (85.6°F).
Note: Temperatures between 25°C (77°F) and 29°C (84.2°F) are ideal for swimming, diving, and similar water activities, ensuring pleasure and comfort for extended periods without feeling uneasy.

Sunshine
November and
December, with an average of 4.3h of sunshine, are months with the least sunshine in Singapore.
UV index
January through
May,
August through December, with an average maximum UV index of 12, are months with the highest UV index in Singapore, Singapore. A UV Index estimate of 11, and higher, represents an extreme threat to health from unsafe exposure to UV radiation for ordinary individuals.
Note: The maximum UV index of 12 during November leads to these instructions:
Employ every precaution of importance, unprotected skin and eyes could burn within moments. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key. After a swim or an outdoor workout, generously apply and regularly reapply a sunscreen with at least SPF 30, even if the day is cloudy. Note! The Sun's UV radiation gets intensified with the reflection from sand and water.
