Weather in August
Temperature
The arrival of August sees an average high-temperature of a still warm 81°F (27.2°C), hardly diverging from July's 81.9°F (27.7°C). Following the sharp contrast to daytime warmth, an average nighttime temperature of 57.7°F (14.3°C) gets registered during August.Heat index
The average heat index in August is calculated to be a tropical 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 are essentially critical for children. 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.
