Weather in September
Temperature
As Kirkwood, South Carolina, steps into September, the average high-temperature holds at a warm 83.3°F (28.5°C), hinting at a minor fluctuation from the prior month. Kirkwood registers a consistent average low-temperature of 66.2°F (19°C) during September.Heat index
The heat index value for September is calculated to be a tropical 89.6°F (32°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
