Weather in September
Temperature
Barclaysville, North Carolina, experiences an average high-temperature of a warm 81.9°F (27.7°C) with the onset of September, subtly varied from August's 86.7°F (30.4°C). Barclaysville's nights in September experience an average temperature drop to a comfortable 64.8°F (18.2°C).Heat index
The heat index in September is calculated to be a hot 87.8°F (31°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. 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. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
