December weather forecast
Uvungu-vungu, Namibia

December, the first month of the summer in Uvungu-vungu, is also a hot month, with temperature in the range of an average high of 31.2°C (88.2°F) and an average low of 21.2°C (70.2°F).

Temperature

The beginning of December records an average high-temperature of a still hot 31.2°C (88.2°F), almost echoing the conditions of the previous month. During the nights in December, the temperature averages to a pleasant 21.2°C (70.2°F).

Heat index

December's heat index is appraised at a fiery hot 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

In December, the average relative humidity is 60%.

Rainfall

In Uvungu-vungu, during December, the rain falls for 18.6 days and regularly aggregates up to 69mm (2.72") of precipitation. Throughout the year, there are 89 rainfall days, and 324mm (12.76") of precipitation is accumulated.

UV index

September, October and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the ordinary person.
Note: An average maximum UV index of 7 in December leads to these recommendations:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
