Temperature

December brings an average high-temperature of a still tropical 30.2°C (86.4°F), showing a slight difference from November's 30.9°C (87.6°F). Nighttime temperatures in Karyamulya, Indonesia, hover around an average low of 25.2°C (77.4°F) in December, a slight descent from daytime highs.

Heat index

For most parts of December, the heat index is computed to be a fiery hot 37°C (98.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Research indicates the heat index considers values in shaded locales and with light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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 has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
