Weather in September
Temperature
Shacklesville, Alabama, experiences a transition to a still tropical 87.1°F (30.6°C) in average high-temperatures with the arrival of September, not greatly differing from August's 90.7°F (32.6°C). Throughout September, Shacklesville witnesses a nighttime temperature average of 67.8°F (19.9°C).Heat index
The heat index for September is computed to be a fiery hot 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 extremely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
