Weather in August
Temperature
Nunnelly observes an average high-temperature of a still hot 87.1°F (30.6°C) in August, barely different from 87.6°F (30.9°C) in July. In August, the recorded average low-temperature is a comfortable 67.1°F (19.5°C).Heat index
August's heat index is estimated at a torrid 102.2°F (39°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
