Weather in September
Temperature
The advent of September denotes an average high-temperature of a still hot 87.3°F (30.7°C), subtly different from August's 92.1°F (33.4°C). In the month of September, West Columbia's average low-temperature falls to a moderately hot 73.6°F (23.1°C).Heat index
The heat index value during September is computed to be a fiery hot 102.2°F (39°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
