Weather in September
September greets Benton with a refreshing change as the city comes down from its summer highs. The temperatures see a remarkable dip from August, indicating the onset of fall. Skip the summer heat, September sees a significant decline to just 1.89" (48mm) of rainfall throughout the month. With less humidity and comfortable temperatures, it makes for pleasant weather, ideal for a swirl of outdoor activities. September is the perfect month to bid farewell to summer and welcome the autumn season.Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a moderately hot 85.3°F (29.6°C) from August's tropical 91.6°F (33.1°C). During September, Benton's temperature falls to a steady low-temperature average of 64.8°F (18.2°C).Heat index
September's heat index is computed to be a torrid 95°F (35°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
