Weather in August
Temperature
The transition from July to August sees an average high-temperature of a still tropical 90.3°F (32.4°C), indicating a minor variance from the prior month. Nightly temperatures drop to an average low of 69.8°F (21°C) in August.Heat index
During August, the heat index is evaluated at a scorching 109.4°F (43°C). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.
