Weather in August
Temperature
In Killeen, August is the warmest month, with temperatures averaging a high of 96.3°F (35.7°C) and a low of 76.1°F (24.5°C).Heat index
The heat index value during August is evaluated at a life-threatening hot 113°F (45°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.Factoring in the heat index, values are geared towards shaded areas with light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
