Weather in September
Temperature
New Chapel Hill observes a small decrease in the average high-temperature with the arrival of September, falling from August's very hot 95°F (35°C) to a hot 88.5°F (31.4°C). During September nights, New Chapel Hill witnesses a consistent average temperature of 67.6°F (19.8°C).Heat index
September's heat index is appraised at a sweltering 100.4°F (38°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
