Temperature

Ngoumbi indicates an average high-temperature of a still hot 31.4°C (88.5°F) in May, showing minor variation from April's 32.3°C (90.1°F). Ngoumbi's nights in May experience an average temperature drop to a warm 23.2°C (73.8°F).

Heat index

The heat index value during May is estimated at a blazing hot 45°C (113°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Heat index values are typically calculated for conditions of shade and a light breeze. 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 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

In May, the average relative humidity is 87%.

Rainfall

In Ngoumbi, in May, it is raining for 27.3 days, with typically 160mm (6.3") of accumulated precipitation. Throughout the year, there are 263 rainfall days, and 1311mm (51.61") of precipitation is accumulated.

UV index

The months with the lowest UV index are March, May through November, with an average maximum UV index of 6. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for ordinary individuals.
Note: The daily high UV index of 6 in May translates into this advice:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
