Weather in September
Temperature
As Arkansas City, Arkansas, steps into September, the average high-temperature is measured at a still tropical 86°F (30°C), displaying minor differences from August's 89.6°F (32°C). Arkansas City, in September, observes a steady average low-temperature of 67.3°F (19.6°C).Heat index
During September, the heat index is estimated at a sweltering 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.When referencing the heat index, its values are suitable for shady environments and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
