December weather forecast
Mongolo, Congo

December, the first month of the summer in Mongolo, is still a tropical month, with temperature in the range of an average high of 31.3°C (88.3°F) and an average low of 21.9°C (71.4°F).

Temperature

December's onset sees an average high-temperature of a still tropical 31.3°C (88.3°F), exhibiting a slight fluctuation from the previous month. During December, Mongolo observes a consistent average nighttime temperature of 21.9°C (71.4°F).

Heat index

December's mean heat index is computed to be a scorching 41°C (105.8°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

In December, the average relative humidity is 77%.

Rainfall

In December, the rain falls for 28 days. Throughout December, 113mm (4.45") of precipitation is accumulated. Throughout the year, there are 277.8 rainfall days, and 1195mm (47.05") of precipitation is accumulated.

On the first day of the month, sunrise is at 05:37 and sunset at 17:52. On the last day of December, in Mongolo, sunrise is at 05:50 and sunset at 18:06 WAT.

Sunshine

The average sunshine in December is 9.5h.

UV index

January through August, October through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for average individuals.
Note: A maximum high daily UV index of 7 during December translates into the following directions:
Ward off overexposure. Defence against solar harm is crucial. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
