Weather in September
Temperature
The advent of September sees the average high-temperature at a still tropical 87.3°F (30.7°C), subtly shifted from August's 90.9°F (32.7°C). Carville records an average nighttime low of 70.5°F (21.4°C) in September.Heat index
In September, the average heat index is calculated to be a blistering 104°F (40°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. 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. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
