Weather in September
Temperature
Wellman's transition from August to September introduces an average high-temperature of a still hot 86.7°F (30.4°C), marking an insignificant variation from the 90.7°F (32.6°C). In Wellman, the average nighttime temperature during September is a comfortable 67.8°F (19.9°C).Heat index
September's average heat index is computed to be a fiery hot 100.4°F (38°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Heat index determinations are made taking into account the shade and light air movements. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Always opt for UVA and UVB-resistant sunglasses on radiant days. Take heed! Reflection from the snow can almost amplify the Sun's UV radiation by double.
