December weather forecast
Mulung, Indonesia

December, the first month of the summer in Mulung, is still a hot month, with an average temperature fluctuating between 31.1°C (88°F) and 24.2°C (75.6°F).

Temperature

As December takes hold, the average high-temperature is a still tropical 31.1°C (88°F), nearly mirroring that of the previous month. An average low-temperature of 24.2°C (75.6°F) is expected during December.

Heat index

Throughout December, the heat index is computed to be a blistering 42°C (107.6°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

The average relative humidity in December is 82%.

UV index

February through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for average individuals.
Note: In December, a daily UV index of 7 turns into the following recommendations:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
