December weather forecast
Kaisosi, Namibia

December, the first month of the summer in Kaisosi, is also a hot month, with an average temperature fluctuating between 21.2°C (70.2°F) and 31.2°C (88.2°F).

Temperature

The onset of December marks an average high-temperature of a still hot 31.2°C (88.2°F), hardly differing from November's 33.3°C (91.9°F). Throughout December, the nighttime temperature averages to a pleasant 21.2°C (70.2°F).

Heat index

The heat index value during December is computed to be a very hot 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
One should consider that heat index numbers are for shaded settings and 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 'real feel' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

In December, the average relative humidity is 60%.

Rainfall

In Kaisosi, during December, the rain falls for 18.6 days and regularly aggregates up to 69mm (2.72") of precipitation. In Kaisosi, during the entire year, the rain falls for 89 days and collects up to 324mm (12.76") of precipitation.

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 health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: In December, the maximum UV index of 7 translates into these guidelines:
Guard against overexposure. Protection from sun-induced harm is essential. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
