The arrival of August brings an average high-temperature of a still tropical 86.5°F (30.3°C), nearly identical to July's 88°F (31.1°C). Throughout the month of August, the average temperature dips to a comfortable 67.8°F (19.9°C) at night.

It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
