Weather in August
Temperature
The onset of August brings an average high-temperature of a still moderately hot 81.9°F (27.7°C), nearly matching the July temperature. Harriett, during the month of August, experiences an average low-temperature of 62.4°F (16.9°C).Heat index
The average heat index in August is calculated to be a hot 87.8°F (31°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Heat index determinations are made taking into account the shade and light air movements. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
