May introduces slight variations in
Singapore's weather compared to the preceding month of
April. Remarkably, the average sea temperature peaks to a warm 30.2°C (86.4°F) - the highest annual sea temperature occurs in this month. Daylight hours extend marginally, enabling residents and tourists to make the most of the daylight. While the city-state continues its cycle of warm days and mild nights, sudden thunderstorms may occur as a result of the high humidity. Retaining most of April's climatic features, May in Singapore is synonymous with consistent tropical weather conditions.
Temperature
May begins with an average high-temperature of a still tropical 31.6°C (88.9°F), reflecting close similarity to the preceding month. Throughout May, Singapore records an average temperature of 24.8°C (76.6°F) at night.
Heat index
For most parts of May, the heat index is computed to be a burning hot 45°C (113°F).
Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
Humidity
In Singapore, Singapore, the average relative humidity in May is 84.4%.
Rainfall
In May, in Singapore, the rain falls for 15 days. Throughout May, 171mm (6.73") of precipitation is accumulated. In Singapore, Singapore, during the entire year, the rain falls for 178 days and collects up to 2343mm (92.24") of precipitation.
Sea temperature
The months with the warmest seawater in Singapore are May and
June, with an average sea temperature of 30.2°C (86.4°F).
Note: Cooling down in waters with temperatures over 30°C (86°F) might not feel as satisfying.
Daylight
The average length of the day in May is 12h and 11min.
On the first day of May in Singapore, sunrise is at 06:56 and sunset at 19:06. On the last day of the month, sunrise is at 06:56 and sunset at 19:08 +08.
Sunshine
In May, the average sunshine in Singapore, Singapore, is 5.8h.
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. A UV Index value of 11, and more, symbolizes an excessive health risk from exposure to the Sun's UV radiation for the ordinary person.
Note: A maximum daily UV index of 12 during May morphs into the following directions:
Employ all critical precautions. Guarding against sun damage is essential. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. During bright days, sunglasses that offer UVA and UVB defense are recommended. Even on overcast days, apply and frequently reapply a sunscreen with SPF 30 or more, specifically after a swim or outdoor workout. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
