Weather in December
Temperature
During December, the average high-temperature is a still moderately hot 27.9°C (82.2°F), maintaining a close resemblance to that of the preceding month. Vaalpark's average low-temperature for the month of December records at a comfortable 16.4°C (61.5°F).Heat index
In December, the heat index is evaluated at 29°C (84.2°F). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
