Weather in December
Temperature
January and December bring Buna's highest average temperatures, reaching a high of 30.1°C (86.2°F).Heat index
December's mean heat index is computed to be a sweltering 37°C (98.6°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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 body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
Humidity
The average relative humidity in December is 78%.Rainfall
In Buna, during December, the rain falls for 29.9 days and regularly aggregates up to 239mm (9.41") of precipitation. Throughout the year, there are 330.7 rainfall days, and 2168mm (85.35") of precipitation is accumulated.Snowfall

Sunshine
In Buna, the average sunshine in December is 10.3h.UV index
The months with the lowest UV index in Buna are February through October and December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: During December, 6 as the daily maximum UV index converts into the following advice:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
