Weather in September
Temperature
Wall Settlement, Louisiana, observes an average high-temperature of a still tropical 88°F (31.1°C) in September, barely different from 91.4°F (33°C) in August. Wall Settlement's nights in September experience an average temperature drop to a pleasant 70.7°F (21.5°C).Heat index
The heat index in September is estimated at a blisteringly hot 104°F (40°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
