Weather in September
Temperature
With the onset of September, the average high-temperature subtly recedes from August's hot 87.4°F (30.8°C) to a warm 80.6°F (27°C). September witnesses an average nighttime temperature of 59.2°F (15.1°C).Heat index
The heat index value for September is calculated to be 84.2°F (29°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
