Weather in September
Temperature
As September begins, there is a minor decrease in the average high-temperature, softly falling from a hot 93.2°F (34°C) in August to a still tropical 86.9°F (30.5°C). In September, the nighttime temperature in Cheatham lowers to an average of 65.5°F (18.6°C).Heat index
September's average heat index is evaluated at a very hot 96.8°F (36°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
