Weather in September

The first month of the autumn, September, is still a tropical month in Gray Point, Louisiana, with an average temperature varying between 86.5°F (30.3°C) and 69.4°F (20.8°C).

Temperature

On the advent of September, Gray Point's average high-temperature exhibits a minor adjustment to a still hot 86.5°F (30.3°C) from August's 90.7°F (32.6°C). September brings with it a nighttime average temperature of 69.4°F (20.8°C).

Heat index

In September, the average heat index is computed to be a very hot 100.4°F (38°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

The average relative humidity in September is 79%.
