Weather in September
Temperature
September's weather displays an average high-temperature of a still hot 86.2°F (30.1°C), slightly varied from August's 89.6°F (32°C). In Bayou Chene, an average nighttime temperature of 72.1°F (22.3°C) is expected during September.Heat index
For most parts of September, the heat index is computed to be a torrid 100.4°F (38°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun could elevate 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. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
