Weather in September
Temperature
Ravenel, South Carolina, marks the onset of September with an average high-temperature of a warm 84.9°F (29.4°C), a subtle shift from August's 88.7°F (31.5°C). During the September nights, an average temperature of 71.8°F (22.1°C) is observed in Ravenel, South Carolina.Heat index
September's mean heat index is computed to be a very hot 95°F (35°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
