Weather in September
Temperature
The onset of September notes an average high-temperature of a still tropical 88°F (31.1°C), subtly shifted from August's 90°F (32.2°C). In Gordonville, the average low-temperature during the month of September is a warm 73.6°F (23.1°C).Heat index
In September, the average heat index is estimated at a blisteringly hot 105.8°F (41°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
