Weather in December
Temperature
In December, South Point notes an average high-temperature of a still warm 27.8°C (82°F), hardly different from the preceding month. South Point's average temperature throughout the nights in December exhibits a minor decrease from daytime highs, stabilizing at a still moderately hot 23.9°C (75°F).Heat index
In December, the heat index is evaluated at a tropical 31°C (87.8°F). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 of high significance for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
