Temperature

Heat index

The average heat index in May is evaluated at a torrid 38.9°C (102°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
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', 'real feel', 'feels like', or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is individual, with diverse people perceiving weather differently for numerous reasons (metabolic differences, differences in body mass, height, and shape, pregnancy), 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 especially crucial for babies and toddlers. 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. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In May, the average relative humidity is 77%.

Rainfall

In Tarakan, during May, the rain falls for 28.1 days and regularly aggregates up to 205mm (8.07") of precipitation. In Tarakan, during the entire year, the rain falls for 329.3 days and collects up to 2189mm (86.18") of precipitation.

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.

Months with the lowest UV index in Tarakan are January through December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to the UV radiation for average individuals.
Note: The daily maximum UV index of 7 interpret into the following advice:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 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. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
