Weather in September
Temperature
With September's advent, Salter, Alabama, sees an average high-temperature of a still tropical 87.1°F (30.6°C), subtly shifted from August's 90.7°F (32.6°C). During the month of September, Salter's nighttime temperature lowers to an average of 67.8°F (19.9°C).Heat index
September's mean heat index is estimated at a sweltering 100.4°F (38°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
