Temperature

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

Heat index

In May, the average heat index is calculated to an extremely hot 44.7°C (112.5°F). Beware - heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature', 'feels like', 'felt air temperature', or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (metabolic differences, clothing, differences in body mass, height, and shape). Be aware that direct exposure to sunlight increases heat impact, and may raise the heat index additionally, by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.

Humidity

In May, the average relative humidity in Singapore is 84.4%.

Rainfall

In Singapore, during 15 rainfall days, 171.3mm (6.74") of precipitation is typically accumulated. In Singapore, during the entire year, the rain falls for 178 days and collects up to 2342.5mm (92.22") 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

Months with the longest days are May through August, with an average of 12.2h of daylight.

Sunshine

The average sunshine in 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. A UV Index value of 11, and more, symbolizes an extreme health hazard from the exposure to the Sun's UV radiation for ordinary individuals.
Note: The daily maximum UV index of 12 interpret into the following advice:
Take all required precautions, as unprotected skin and eyes can burn in minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. 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.
