Weather in September
Temperature
As August makes way for September, Antoine's average high-temperature eases from a hot 92.5°F (33.6°C) to a still tropical 86.4°F (30.2°C). Antoine's nights in September experience an average temperature drop to a refreshing 64.9°F (18.3°C).Heat index
In September, the heat index is appraised at a sweltering 96.8°F (36°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
