Weather in September
Temperature
The advent of September brings an average high-temperature of a still hot 87.4°F (30.8°C), almost identical to the preceding month. Cheraw, in the month of September, anticipates a consistent average low-temperature of 68.2°F (20.1°C).Heat index
The heat index value during September is appraised at a fiery hot 102.2°F (39°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
