Weather in September
Temperature
The start of September comes with a small reduction in the average high-temperature, subtly receding from a very hot 95.2°F (35.1°C) in August to a tropical 87.3°F (30.7°C). Throughout the month of September, Granite Shoals observes an average nighttime temperature of 68.9°F (20.5°C).Heat index
September's average heat index is evaluated at a torrid 96.8°F (36°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
