The average heat index in August is evaluated at 82.4°F (28°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
