Weather in August
Temperature
The advent of August denotes an average high-temperature of a warm 84.9°F (29.4°C), subtly different from July's 86.2°F (30.1°C). In Gibsonia, the average nighttime temperature during August is a refreshing 66.2°F (19°C).Heat index
In August, the heat index is estimated at a sweltering 95°F (35°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

A UV Index estimate of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for average individuals.Note: A maximum UV index of 6 in August translates into the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
