Temperature

Boma, Democratic Republic of Congo, notes the coldest temperatures in December, with a high average of 30.2°C (86.4°F) and a low of 22.8°C (73°F).

Heat index

The heat index value during December is calculated to be an extremely hot 40°C (104°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

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

Note: The UV index of 6 during December leads to these advisories:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
