Weather in September
Temperature
As Atmore transitions into September, the average high-temperature stands at a still tropical 87.4°F (30.8°C), offering little variation from the preceding month. September generally records an average low-temperature of 68.4°F (20.2°C).Heat index
In September, the average heat index is computed to be a fiery hot 102.2°F (39°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
