Weather in September
Temperature
The initiation of September sees an average high-temperature of a still tropical 87.4°F (30.8°C), showing minor variations from the previous month. In Moncla, September nights cool down to an average of 68.5°F (20.3°C).Heat index
During September, the heat index is computed to be a torrid 102.2°F (39°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
