Weather in August
Temperature
August's presence records an average high-temperature of a still tropical 92.5°F (33.6°C), closely mirroring July's climate. Nighttime temperatures in Heavener exhibit a substantial dip from daytime highs during August, averaging at an agreeable 69.4°F (20.8°C).Heat index
The heat index value during August is calculated to be a life-threatening hot 113°F (45°C). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.Heat index data is primarily for areas with shade and subjected to light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
