Weather in September
Temperature
As August transitions into September, the average high-temperature rests at a still hot 87.4°F (30.8°C), maintaining a close resemblance to the previous month. In Schley, the September nights cool down to an average low of 67.8°F (19.9°C).Heat index
September's average heat index is calculated to be a sweltering 102.2°F (39°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 hold particular importance for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
