Weather in September
Temperature
As August transitions into September, Bon Ami sees a gentle drop in the average high-temperature, transitioning from 93.6°F (34.2°C) to a still tropical 88.2°F (31.2°C). Bon Ami records an average temperature drop to a pleasant 69.1°F (20.6°C) in September.Heat index
For September, the heat index is computed to be a blistering 104°F (40°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. 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 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
