Mtsamdou experiences an average nighttime temperature of 27°C (80.6°F) in December, reflecting a minor difference from the day's peak.Heat index
December's mean heat index is evaluated at a tropical 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. 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 highly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
