Weather in September
Temperature
With the commencement of September, Buckner records a moderate temperature decline, with the average high easing from August's 93.7°F (34.3°C) to a still hot 87.1°F (30.6°C). Buckner, during the month of September, experiences an average low-temperature of 65.8°F (18.8°C).Heat index
In September, the heat index is estimated at a torrid 98.6°F (37°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
