Weather in September
Temperature
In September, Shenandoah experiences a minor shift in meteorological conditions with average high-temperatures marked at a still tropical 88.3°F (31.3°C), closely mirroring the climate in August. An average nighttime temperature of 70°F (21.1°C) is observed in Shenandoah during September.Heat index
In September, the average heat index is appraised at a blisteringly hot 105.8°F (41°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
