Weather in August
Temperature
The arrival of August records an average high-temperature of a still hot 87.4°F (30.8°C), closely related to the 88.3°F (31.3°C) observed in July. During the nights in August, Couchville observes an average low-temperature of 68.5°F (20.3°C).Heat index
For most parts of August, the heat index is calculated to be a fiery hot 100.4°F (38°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.For clarity, heat index numbers account for light winds and areas under shade. 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', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
