Weather in September

The first month of the autumn, September, is still a tropical month in Fountain, Alabama, with an average temperature varying between 68°F (20°C) and 88°F (31.1°C).

Temperature

During September, Fountain observes a subtle ascent to a still hot 88°F (31.1°C) from August's 91.9°F (33.3°C) in the average high-temperature. Throughout the month of September, Fountain witnesses an average low-temperature of 68°F (20°C).

Heat index

September's heat index is evaluated at a sweltering 102.2°F (39°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
