Ciputri, Indonesia

The first month of the summer, December, is still a hot month in Ciputri, Indonesia, with an average temperature varying between 24.5°C (76.1°F) and 30.2°C (86.4°F).

Temperature

December's weather displays an average high-temperature of a still tropical 30.2°C (86.4°F), slightly varied from November's 31°C (87.8°F). During the month of December, an average temperature of 24.5°C (76.1°F) is noted during the nights.

Heat index

For most parts of December, the heat index is computed to be a very hot 37°C (98.6°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Metrics for the heat index primarily focus on shaded spots 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 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 extremely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

The average relative humidity in December is 77%.

Note: A maximum high UV index of 7 in December translates into the following recommendations:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
