Weather in September
Temperature
A subtle change in temperatures is noted as August gives way to September, with average highs reducing from a tropical 91.9°F (33.3°C) to a warm 83.7°F (28.7°C). Attica's temperature in September lowers to a consistent average of 64.9°F (18.3°C) during the nights.Heat index
September's average heat index is estimated at a hot 87.8°F (31°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
