Weather in September
Temperature
Harrells's average high-temperature in September is a warm 82.6°F (28.1°C), marking an insignificant difference from the 87.4°F (30.8°C) of August. An average low-temperature of 66.4°F (19.1°C) is noted during the nights in September.Heat index
The heat index value during September is evaluated at a hot 89.6°F (32°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
