Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a torrid 95°F (35°C) in August to a hot 88.9°F (31.6°C). South Mansfield's nights in September experience an average temperature drop to a comfortable 67.6°F (19.8°C).Heat index
September's average heat index is calculated to be an extremely hot 104°F (40°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Heat index determinations are made taking into account the shade and light air movements. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. 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. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
