Weather in August
Temperature
The shift into August records an average high-temperature of a still tropical 87.4°F (30.8°C), subtly varied from July's 90.3°F (32.4°C). August nights experience a consistent temperature drop to a comfortable 66.2°F (19°C).Heat index
August's mean heat index is evaluated at a fiery hot 100.4°F (38°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
