Weather in September
Temperature
In September, the average high-temperature in Shreveport, Louisiana, marginally decreases from a very hot 95.5°F (35.3°C) in August to a tropical 89.1°F (31.7°C). Shreveport's nights in September experience an average temperature drop to an agreeable 68.4°F (20.2°C).Heat index
During September, the heat index is evaluated at a fiery hot 102.2°F (39°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
