Weather in September
Temperature
With the advent of September, Troy's high-temperatures adjust to a still tropical 86.9°F (30.5°C), closely aligning with the preceding month. An average nighttime temperature of 67.8°F (19.9°C) is witnessed throughout September.Heat index
During September, the heat index is appraised at a sweltering 98.6°F (37°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
