Weather in September

The initiation of September sees an average high-temperature of a still tropical 87.8°F (31°C), showing minor variations from the previous month. In September, Dukes encounters an average low-temperature of 71.6°F (22°C) during the night.Heat index
September's heat index is evaluated at an extremely hot 104°F (40°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. 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 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
