Weather in September
Temperature
September implies a soft temperature shift, with average high-temperatures reducing from August's tropical 90.1°F (32.3°C) to a warm 84.6°F (29.2°C). Vilonia, during September, witnesses an average low-temperature of 64.8°F (18.2°C).Heat index
September's average heat index is evaluated at a tropical 93.2°F (34°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
