Weather in September
Temperature
As August transitions into September, Duette records an average high-temperature of a still tropical 88.3°F (31.3°C), showing a gentle shift from the preceding month. The average low-temperature during September nights is a warm 74.8°F (23.8°C).Heat index
During September, the heat index is estimated at a scorching 105.8°F (41°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
