The first month of the autumn, September, is still a tropical month in Creston, Louisiana, with an average temperature fluctuating between 68°F (20°C) and 88.9°F (31.6°C).

Temperature

The advent of September brings a subtle shift in temperature, with the average high moving from 94.3°F (34.6°C) in August to a still tropical 88.9°F (31.6°C). Throughout September, Creston's nights cool down to an average of 68°F (20°C).

Heat index

September's mean heat index is calculated to be an extremely hot 104°F (40°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.
Understanding the heat index involves considering values for shaded locales with light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
