The transition into September involves a small decrease in the average high-temperature, dipping slightly from a hot 87.3°F (30.7°C) in August to a warm 81.5°F (27.5°C). Aurora in September experiences a low-temperature average of 62.1°F (16.7°C).Heat index
During September, the heat index is evaluated at a hot 86°F (30°C). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children.
