Weather in August
Temperature
The arrival of August coincides with an average high-temperature of a moderately hot 85.8°F (29.9°C), indicating a minimal shift from July's 88°F (31.1°C). In Carter, the average temperature during the nights of August marks a significant drop from the daily high, settling at an enjoyable 63.9°F (17.7°C).Heat index
In August, the average heat index is evaluated at a hot 89.6°F (32°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light 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 'feels like' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
