Weather in August
Temperature
The initiation of August sees an average high-temperature of a still tropical 92.1°F (33.4°C), showing minor variations from the previous month. August's average low-temperature reading settles at a pleasant 72.3°F (22.4°C).Heat index
During August, the heat index is estimated at a blazing hot 114.8°F (46°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Observations indicate that the heat index values are for shady locations with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
