Weather in August
Temperature
The ushering in of August brings an average high-temperature of a still hot 92.8°F (33.8°C), closely mirroring the 93.2°F (34°C) of July. Joan, in August, experiences a marked contrast from daytime zeniths to a steady average low-temperature of 71.1°F (21.7°C).Heat index
August's heat index is evaluated at a burning hot 116.6°F (47°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
