Weather in September

The first month of the autumn, September, is still a tropical month in Salter, Alabama, with an average temperature varying between 67.8°F (19.9°C) and 87.1°F (30.6°C).

The initiation of September sees an average high-temperature of a still tropical 87.1°F (30.6°C), showing minor variations from the previous month. Salter's temperature in September lowers to a consistent average of 67.8°F (19.9°C) during the nights.

Heat index

In September, the heat index is evaluated at a sweltering 100.4°F (38°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
