September, the first month of the autumn in South Bend, is still a tropical month, with temperature in the range of an average low of 68.5°F (20.3°C) and an average high of 87.4°F (30.8°C).

Temperature

Onset of September comes with a temperature decline, the average high falling from a very hot 96.8°F (36°C) in August to a hot 87.4°F (30.8°C). In the month of September, an average of 68.5°F (20.3°C) marks the low-temperature.

Heat index

For most parts of September, the heat index is appraised at a sweltering 95°F (35°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
