Weather in August
Temperature
The onset of August brings an average high-temperature of a still moderately hot 82.2°F (27.9°C), nearly matching the July temperature. In Hallie, the August nights descend to a significantly cooler average of 59.5°F (15.3°C) compared to daytime highs.Heat index
August's mean heat index is appraised at a tropical 89.6°F (32°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
