Weather in August
Temperature
The transition into August is marked with an average high-temperature of a still moderately hot 81.5°F (27.5°C), showing an insignificant shift from July's 83.3°F (28.5°C). During August, Valley Grove experiences an average low-temperature of 60.1°F (15.6°C) at night.Heat index
For August, the heat index is evaluated at a tropical 87.8°F (31°C). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.Note that heat index values are valued for light wind and location in the shade. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
