Weather in September

White Hall's transition from August to September introduces an average high-temperature of a warm 85.8°F (29.9°C), marking an insignificant variation from the 90.7°F (32.6°C). Nighttime temperature in White Hall, Arkansas, experiences an average drop to a comfortable 66.2°F (19°C) in September.Heat index
September's average heat index is calculated to be a very hot 95°F (35°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.For clarity, heat index numbers account for light winds and areas under shade. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. 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. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
