Weather in September
Temperature
The average high-temperature slightly decreases in September, shifting from a sweltering 97.3°F (36.3°C) in August to a tropical 90.9°F (32.7°C). Bentonville, in the month of September, anticipates a consistent average low-temperature of 75.2°F (24°C).Heat index
The average heat index in September is appraised at a blisteringly hot 107.6°F (42°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. 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. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
