Weather in September
Temperature
As August transitions into September, Florence sees a gentle drop in the average high-temperature, transitioning from a sweltering 95.9°F (35.5°C) to a tropical 87.8°F (31°C). Florence's average low-temperature in the month of September is recorded at an agreeable 70.7°F (21.5°C).Heat index
September's average heat index is appraised at a sweltering 96.8°F (36°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
