Weather in August
Temperature
August registers an average high-temperature of a still hot 86.7°F (30.4°C), slightly varied from July's 87.6°F (30.9°C). In August, in Castle Hayne, the average low-temperature is a warm 74.7°F (23.7°C).Heat index
The heat index value during August is appraised at a sweltering 100.4°F (38°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
