Weather in December
Temperature
The shift into December records an average high-temperature of a still warm 28.1°C (82.6°F), subtly varied from November's 27.8°C (82°F). Doornpoort records a steady low-temperature average of 17.1°C (62.8°F) during December.Heat index
For most parts of December, the heat index is estimated at a hot 30°C (86°F). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
