Weather in August
Temperature
In Willis, August is identified by the highest average temperatures, reaching a peak of 95.5°F (35.3°C) and a low of 74.8°F (23.8°C).Heat index
The heat index value for August is evaluated at a life-threatening hot 123.8°F (51°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
