Weather in August
Temperature
The beginning of August reveals an average high-temperature of a warm 85.6°F (29.8°C), showing minimal deviation from the previous month. Throughout the nights in August, West McLean experiences an average low-temperature of 67.6°F (19.8°C).Heat index
August's average heat index is calculated to be a sweltering 95°F (35°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
