As July transitions into August, the average high-temperature rests at a still moderately hot 82.9°F (28.3°C), maintaining a close resemblance to the previous month. Weyers Cave records a consistent low-temperature average of 60.6°F (15.9°C) during August, indicating a significant difference from the daytime heat.Heat index
For most parts of August, the heat index is evaluated at a tropical 89.6°F (32°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 essentially critical for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
