Temperature

May ushers in an average high-temperature of a very hot 38.3°C (100.9°F), aligning closely with the preceding month. In May, Rijau's temperature tends to fall to an average low of 27.9°C (82.2°F) during the night.

Heat index

May's heat index is computed to be a burning hot 48°C (118.4°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Note: The daily high UV index of 8 during May translates into the following recommendations:
Be sure to take precautions. Without protection, skin might suffer damage quickly. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
