Weather in September
Temperature
The arrival of September corresponds with a minor reduction in the average high-temperature, down from August's torrid 95.9°F (35.5°C) to a tropical 89.4°F (31.9°C). September's nights in Shepherd observe an average temperature of 69.4°F (20.8°C).Heat index
September's heat index is calculated to be an extremely hot 107.6°F (42°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
