Weather in September

September in Shreveport marks the gradual end of the intense summer heat. The month sees a decrease in average temperatures, providing a gallant reprieve from the relentless summer. It's a transition period, where the city starts to bid farewell to the summer and slowly ushers in the crispy fall weather. Despite the dip in temperatures, the weather remains warm enough for outdoor activities. Step by step, the warm summer gives way to a slightly cooler October.

Temperature

A moderate decline in average high-temperatures is noted in September, moving from a fiery hot 95.5°F (35.3°C) in August to a hot 89.1°F (31.7°C). Nightly temperatures in Shreveport drop to an average low of 68.4°F (20.2°C) in September.

Heat index

During September, the heat index is computed to be a fiery hot 102.2°F (39°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
