Weather in September
Temperature
Copperas Cove's progression into September involves a gentle drop in the average high-temperature, from a very hot 95.5°F (35.3°C) in August to a tropical 87.6°F (30.9°C). In September, Copperas Cove records an average nighttime temperature of 70.7°F (21.5°C).Heat index
September's mean heat index is estimated at a fiery hot 96.8°F (36°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
