Weather in September
Temperature
The beginning of September brings a minor change in the average high-temperature, shifting from a hot 93°F (33.9°C) in August to a moderately hot 84.9°F (29.4°C). In the month of September, Cherokee witnesses a consistent average low-temperature of 66.4°F (19.1°C).Heat index
The heat index for September is evaluated at a hot 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
