Weather in August
Temperature
August's onset brings an average high-temperature of a still tropical 86.7°F (30.4°C), showing a minute difference from July's 87.3°F (30.7°C). A sharp contrast between day and night is prevalent in August with an average nighttime temperature of 64.8°F (18.2°C).Heat index
August's heat index is calculated to be a fiery hot 98.6°F (37°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
