The first month of the summer, December, is also a hot month in Mupini, Namibia, with an average temperature ranging between min 21.2°C (70.2°F) and max 31.2°C (88.2°F).

Temperature

December notes an average high-temperature of a still hot 31.2°C (88.2°F), subtly differing from November's 33.3°C (91.9°F). Throughout December, an average low-temperature of 21.2°C (70.2°F) is expected.

Heat index

December's heat index is calculated to be a sweltering 35°C (95°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Know that the heat index computations account for shaded terrains and slight winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

The average relative humidity in December is 60%.

UV index

The months with the highest UV index are September, October and December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the average person.
Note: The maximum UV index, 7 during December, leads to the following recommendations:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
