August's mean heat index is calculated to be 82.4°F (28°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 particularly important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
