Temperature

Dexter's August average high-temperature settles at a still hot 90.7°F (32.6°C), showing a near match with the preceding month. August witnesses an average low-temperature hovering around an agreeable 72°F (22.2°C).

Heat index

August's average heat index is evaluated at a blistering 109.4°F (43°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
