Weather in September
Temperature
Greenwood Springs's weather subtly changes with the onset of September, barely falling from a tropical 90.5°F (32.5°C) in August to a moderately hot 85.1°F (29.5°C). Throughout September, an average low-temperature of 65.3°F (18.5°C) is experienced in Greenwood Springs.Heat index
September's mean heat index is evaluated at a very hot 95°F (35°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
