Weather in August
Temperature
With the onset of August, a modest change to a still tropical 87.3°F (30.7°C) from July's 87.8°F (31°C) is noted in high-temperature. An average minimum temperature of 68.9°F (20.5°C) is recorded during the month of August.Heat index
August's heat index is computed to be a sweltering 102.2°F (39°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 are particularly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
