For most parts of August, the heat index is computed to be 84.2°F (29°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.

A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity.
