Weather in September
Temperature
September indicates a minor shift in the average high-temperature, from August's torrid 97.3°F (36.3°C) to a tropical 90.1°F (32.3°C). During September, Yancey experiences an average low-temperature of 72.1°F (22.3°C) at night.Heat index
September's heat index is computed to be a blisteringly hot 104°F (40°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Realize that the values for the heat index are set for shaded places and light winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
