The beginning of August reveals an average high-temperature of a still warm 81.5°F (27.5°C), showing minimal deviation from the previous month. Halleck's nighttime average of 58.3°F (14.6°C) during August reflects a substantial decrease from the daytime temperature.Heat index
The average heat index in August is evaluated at a tropical 87.8°F (31°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
