Weather in September
Temperature
The arrival of September corresponds with a light shift in temperature, down from a hot 88.7°F (31.5°C) in August to a moderately hot 83.3°F (28.5°C). Throughout the September nights, Piedmont encounters a low-temperature of 63.1°F (17.3°C).Heat index
September's mean heat index is computed to be a hot 89.6°F (32°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.When referencing the heat index, its values are suitable for shady environments 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 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
