Weather in August
Temperature
August ushers in an average high-temperature of a still tropical 92.3°F (33.5°C), aligning closely with the preceding month. Williams notes a substantial temperature decline from the daytime peaks throughout August, with an average nighttime temperature of 69.4°F (20.8°C).Heat index
The average heat index in August is computed to be a blazing hot 113°F (45°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
