December in Mambasa brings a significant transformation in the fashion of mild and pleasant weather. Notably, the city receives only 75mm (2.95") of rainfall in December, closing out the wet phase. Comparatively cooler nights are experienced due to a considerable drop in the night-time temperature. The weather in December suggests the arrival of the winter season, replacing the humidity and heat of the previous months. The city, therefore, gears up to welcome the festivities amidst the colder climate.

Temperature

December's average high-temperature is a tropical 30.4°C (86.7°F), maintaining a close comparison with November's 28.9°C (84°F). Despite drastic daily temperature oscillations, Mambasa cools down to an average low-temperature of 17.8°C (64°F) in December.

Heat index

The average heat index in December is computed to be a very hot 37°C (98.6°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

In December, the average relative humidity is 72%.

Shield from overexposure. Defense against sun-related harm is required. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
