December weather forecast
Maridi, South Sudan

As the year ends, December concludes the weather cycle in Maridi with a significant shift towards drier conditions. The weather becomes much cooler compared to the preceding months, with lower humidity levels and an increased amount of sunlight. The gentle wind blowing at an average speed of 7.6km/h (4.7mph) complements these conditions, adding a chilly edge to the weather. Important to note, temperatures during this period register between 21.6°C (70.9°F) and 33.7°C (92.7°F). Eventually, with accumulated rainfall measuring a mere 9mm (0.35"), December witnesses the driest conditions in the calendar year.

Temperature

The advent of December sees the average high-temperature at a still hot 33.7°C (92.7°F), subtly shifted from November's 31°C (87.8°F). Despite considerable daily temperature swings, a steady low-temperature average of 21.6°C (70.9°F) is noted throughout December.

Heat index

For most parts of December, the heat index is estimated at a fiery hot 35°C (95°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Note: In December, the average maximum UV index of 7 translates into the following recommendations:
Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Boost your sun resistance with garments that are densely woven yet spacious.
