Weather in September
Temperature
As August makes way for September, Cumnock's average high-temperature eases from a tropical 88°F (31.1°C) to a warm 82.6°F (28.1°C). During September, Cumnock observes a consistent average nighttime temperature of 64°F (17.8°C).Heat index
September's average heat index is computed to be a tropical 89.6°F (32°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 are of high significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
