August's mean heat index is calculated to be a hot 86°F (30°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are essentially critical for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
