Morganza, Louisiana begins to cool in September, indicating the initial hints of autumn. Weather conditions exhibit a perceptible change in pattern from August through to October. September reports a decline in peak temperatures to 87.8°F (31°C), marking the initial phases of thermal depletion.

Temperature

Morganza marks the start of September with an average high-temperature of a still tropical 87.8°F (31°C), hinting at a slight fluctuation from August's 91.6°F (33.1°C). Nighttime temperature dips to a mean of 69.1°F (20.6°C) during September.

Heat index

September's mean heat index is estimated at an extremely hot 105.8°F (41°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
