Weather in September
Temperature
With September's arrival, Archer City sees a decrease in average high-temperatures, moving from a very hot 97.3°F (36.3°C) in August to a hot 87.6°F (30.9°C). Throughout September, the average low-temperature records at a pleasant 68.7°F (20.4°C).Heat index
September's average heat index is estimated at a sweltering 95°F (35°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. 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 quite important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
