Weather in September
Temperature
Oswald Place, South Carolina, records an average high-temperature of a moderately hot 82.6°F (28.1°C) as September arrives, nearly mirroring the previous month's climate. In September, a low-temperature average of 74.3°F (23.5°C) is characteristic of Oswald Place, marking a minor shift from daytime temperatures.Heat index
The average heat index in September is computed to be a hot 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. 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.
