September, the first month of the autumn in Carlisle, is still a tropical month, with an average temperature varying between 88.2°F (31.2°C) and 67.6°F (19.8°C).

On the advent of September, Carlisle's average high-temperature exhibits a minor adjustment to a still tropical 88.2°F (31.2°C) from August's 92.1°F (33.4°C). During September, the average low-temperature is a comfortable 67.6°F (19.8°C).

Heat index data is primarily for areas with shade and subjected to light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
