Weather in December

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

Temperature

December's presence marks an average high-temperature of a still tropical 31.2°C (88.2°F), subtly varied from November's 33.3°C (91.9°F). During December, Zone observes a consistent average nighttime temperature of 21.2°C (70.2°F).

Heat index

Throughout December, the heat index is calculated to be a fiery hot 35°C (95°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

In Zone, the average relative humidity in December is 60%.

Rainfall

In Zone, Namibia, in December, during 18.6 rainfall days, 69mm (2.72") of precipitation is typically accumulated. In Zone, during the entire year, the rain falls for 89 days and collects up to 324mm (12.76") of precipitation.

Daylight

With an average of 13h and 12min of daylight, December has the longest days of the year.
On the first day of December, sunrise is at 06:02 and sunset at 19:09. On the last day of the month, sunrise is at 06:15 and sunset at 19:24 CAT.

Sunshine

The average sunshine in December is 10.2h.

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 risk from exposure to the Sun's UV radiation for average individuals.
Note: In December, the maximum UV index of 7 translates into these guidelines:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
