Weather in September

The first month of the autumn, September, is still a tropical month in Linville, Louisiana, with an average temperature varying between 67.1°F (19.5°C) and 87.8°F (31°C).

Temperature

A minor decrease in the average high-temperature is observed during September, shifting from a tropical 93.7°F (34.3°C) in August to a still hot 87.8°F (31°C). In Linville, an average nighttime temperature of 67.1°F (19.5°C) is expected during September.

Heat index

September's mean heat index is computed to be a very hot 100.4°F (38°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
