Weather in May

May, the last month of the spring in Singapore, is another tropical month, with an average temperature varying between 31.6°C (88.9°F) and 24.8°C (76.6°F).

Temperature

In May, the average high-temperature is relatively the same as in April - a still tropical 31.6°C (88.9°F). In Singapore, the average low-temperature is 24.8°C (76.6°F).

Heat index

The average heat index in May is evaluated at a blazing hot 45°C (113°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like', 'real feel', 'apparent temperature', or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is individual, with diverse people perceiving weather differently for numerous reasons (pregnancy, differences in body mass, height, and shape, clothing), and activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Humidity

The average relative humidity in May is 84.4%.

Rainfall

In May, the rain falls for 15 days. Throughout May, 171mm (6.73") of precipitation is accumulated. In Singapore, during the entire year, the rain falls for 178 days and collects up to 2343mm (92.24") of precipitation.

Sea temperature

May and June, with an average sea temperature of 30.2°C (86.4°F), are months with the warmest seawater.
Note: The water temperature above 30°C (86°F) is arguably regarded as unpleasant. The primary purpose of entering the water - cooling down from sunshine and high temperatures - is lost.

Daylight

In Singapore, the average length of the day in May is 12h and 11min.
On the first day of the month, sunrise is at 06:56 and sunset at 19:06. On the last day of May, in Singapore, sunrise is at 06:56 and sunset at 19:08 +08.

UV index

The months with the highest UV index in Singapore are January through May, August through December, with an average maximum UV index of 12. A UV Index value of 11, and more, symbolizes an ultimate health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: The daily maximum UV index of 12 in May interpret into the following advice:
Practice all-important precautions. Light skin people may get burned in less than 5 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
