September's onset sees an average high-temperature of a still tropical 86.9°F (30.5°C), exhibiting a slight fluctuation from the previous month. In the month of September, Mount Nebo witnesses a consistent average low-temperature of 66.6°F (19.2°C).

Heat index

The heat index value during September is appraised at a fiery hot 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. 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.
