Weather in August
Temperature
Entering August, the average high-temperature is recorded at a still tropical 86.5°F (30.3°C), exhibiting a minimal shift from July's 88.2°F (31.2°C). August's nights observe an average temperature of 67.3°F (19.6°C).Heat index
Throughout August, the heat index is appraised at a fiery hot 98.6°F (37°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. 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. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
