Weather in September
Temperature
With September's arrival, Sieper notes an average high-temperature of a still hot 87.4°F (30.8°C), closely following the trend of the preceding month. During September, Sieper experiences an average low-temperature of 68.4°F (20.2°C) at night.Heat index
During September, the heat index is estimated at a torrid 102.2°F (39°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
