December weather forecast
Boma, Democratic Republic of Congo

December rounds off the year in Boma, keeping the wet weather pattern consistent. It stands out with the most precipitation, a significant 194mm (7.64"), marking its peak in the annual rainfall pattern. Despite the surge in rainfall, the temperature and weather conditions don't differ significantly from November. As the rainy days rise, the city looks cloudy with lower visibility. The atmospheric pressure is back to the levels observed in the year's start, bringing the climatic cycle full circle.

Temperature

December is the month when Boma sees the lowest average temperatures, with a high of 30.2°C (86.4°F) and a low of 22.8°C (73°F).

Heat index

During December, the heat index is estimated at a scorching 40°C (104°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Humidity

April and December, with an average relative humidity of 85%, are the most humid months in Boma.

UV index

The months with the lowest UV index are February, June through August, October and December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: A maximum high daily UV index of 6 during December translates into the following directions:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
