Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a hot 87.8°F (31°C) in August to a moderately hot 81.9°F (27.7°C). In September, the temperature in Bumpus Mills drops to an average of 61.9°F (16.6°C) at night.Heat index
Throughout September, the heat index is estimated at a tropical 87.8°F (31°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
