Weather in September
Temperature
The shift to September signals an average high-temperature of a warm 85.6°F (29.8°C), subtly varied from August's 89.8°F (32.1°C). September brings with it a nighttime average temperature of 66.4°F (19.1°C) in Shannon Tank, Arkansas.Heat index
In September, the heat index is computed to be a torrid 95°F (35°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
