Weather in September

The first month of the autumn, September, is still a tropical month in Arcola, Alabama, with an average temperature varying between 67.1°F (19.5°C) and 87.6°F (30.9°C).

With the advent of September, Arcola experiences an average high-temperature of a still hot 87.6°F (30.9°C), mirroring a close resemblance to the previous month. The mean low-temperature during September nights is a comfortable 67.1°F (19.5°C).

Heat index

For most parts of September, the heat index is evaluated at a very hot 100.4°F (38°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. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
