Weather in September
Temperature
The arrival of September in Foley, Alabama, sees an average high-temperature of a still hot 86°F (30°C), hardly diverging from August's 89.1°F (31.7°C). In Foley, the average temperature during the nights of September drops to a warm 74.5°F (23.6°C).Heat index
Throughout September, the heat index is estimated at a very hot 96.8°F (36°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
