Weather in September
Temperature
September's arrival comes with a mild decrease in the average high-temperature, moving subtly from a fiery hot 95.9°F (35.5°C) in August to a hot 88°F (31.1°C). During the month of September, Niederwald anticipates a mean low-temperature of 70.5°F (21.4°C).Heat index
The average heat index in September is calculated to be a sweltering 100.4°F (38°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
