August is the warmest month, with an average high-temperature of 93.9°F (34.4°C) and an average low-temperature of 72.1°F (22.3°C).Heat index
The heat index value during August is evaluated at a blazing hot 116.6°F (47°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
