Weather in September
Temperature
Coupland, Texas, observes a small decrease in the average high-temperature with the arrival of September, falling from August's very hot 96.4°F (35.8°C) to a tropical 88.7°F (31.5°C). Coupland in September anticipates an average nighttime temperature of 70.7°F (21.5°C).Heat index
In September, the average heat index is computed to be a fiery hot 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
