December weather forecastSachona, Namibia

Weather in December

December, the first month of the summer in Sachona, is still a tropical month, with an average temperature varying between 31.6°C (88.9°F) and 21.3°C (70.3°F).

Temperature

December's presence marks an average high-temperature of a still hot 31.6°C (88.9°F), subtly varied from November's 34.2°C (93.6°F). In Sachona, the average low-temperature during the month of December is an agreeable 21.3°C (70.3°F).

Heat index

The heat index value during December is computed to be a torrid 37°C (98.6°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. 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 especially crucial for 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 is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In December, the average relative humidity in Sachona is 63%.

Rainfall

In Sachona, in December, during 23.9 rainfall days, 124mm (4.88") of precipitation is typically accumulated. In Sachona, during the entire year, the rain falls for 121.1 days and collects up to 537mm (21.14") of precipitation.

UV index

In Sachona, the average daily maximum UV index in December is 6. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for the average person.
Note: In December, a daily maximum UV index of 6 leads to the following instructions:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Stay sun-safe with clothing that is both closely woven and worn loosely.
