Temperature

Arrow indicates an average high-temperature of a still tropical 86.5°F (30.3°C) in August, showing minor variation from July's 87.4°F (30.8°C). In the month of August, an average of 67.3°F (19.6°C) marks the low-temperature.

Heat index

The average heat index in August is computed to be a very hot 98.6°F (37°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light 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', gives a temperature feeling by integrating air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one'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 extremely vital to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. 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. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
