Weather in December
Temperature
Sterkstroom's weather in December, with an average high-temperature of a still moderately hot 28.2°C (82.8°F), subtly shifts from November's 26°C (78.8°F). Despite a significant deviation from daily highs, December sees an average nighttime temperature of 14.7°C (58.5°F).Heat index
In December, the average heat index is calculated to be 28°C (82.4°F). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.

Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
