Weather in December
Temperature
The transition from November to December sees average high-temperatures adjusting to a moderately hot 29.6°C (85.3°F), from a not significantly different 31°C (87.8°F). During the month of December, Mongombi experiences a steady low-temperature average of 20.5°C (68.9°F).Heat index
During December, the heat index is computed to be a hot 31°C (87.8°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
