Weather in September
Temperature
An average high-temperature of a still tropical 87.4°F (30.8°C) marks September, exhibiting a close resemblance to the conditions in August. Moss Bluff observes an average nighttime low-temperature of 71.2°F (21.8°C) during the month of September.Heat index
Throughout September, the heat index is appraised at a very hot 102.2°F (39°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
