Weather in September
Temperature
Gunnison in September witnesses an average high-temperature of a warm 85.6°F (29.8°C), indicating a slight variation from August's 89.6°F (32°C). Throughout September nights, Gunnison registers an average low-temperature of 66.9°F (19.4°C).Heat index
September's heat index is computed to be a torrid 95°F (35°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.The metrics for the heat index are tailored for both shady environments and light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
