Weather in September
Temperature
Eagle's shift from August to September is accompanied by an average high-temperature of a still warm 80.8°F (27.1°C), a slight deviation from 85.6°F (29.8°C). During the month of September, the temperature falls to an average of 60.4°F (15.8°C).Heat index
September's mean heat index is computed to be 84.2°F (29°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
